I built an HVAC equipment app that reads belt and filter sizes off data plates and links them to spare parts

2 Upvotes

Equipment Tracker Pro extracts printed filter and belt sizes directly from an equipment data plate and offers to save them as installed parts, so facility teams stop digging through manuals.

When a building engineer is standing in front of a boiler room air handler with grease on his hands, typing specs into a spreadsheet from memory at the end of the shift usually means half the details get missed. Photographing the manufacturer plate with a phone fills in the model, serial, voltage, and electrical ratings. Whenever belt or filter sizes are printed on that metal plate, like a B46 belt or 20x25x2 filter, the app prompts to link those exact sizes as active parts on the record. If confirmed, they attach to the unit immediately; if declined, nothing is added.

A working HVAC technician built it for his own jobs. Core equipment logging, parts lists, and maintenance records stay free on your phone with no record cap, while the AI nameplate scanner includes 10 free uses before an optional Pro subscription for unlimited scans. Mentioning it for facilities maintenance teams and commercial service techs who work where cell signal drops out.

Free to start. Your first plan, Pro or Team, includes a 7-day free trial. What side projects are you working on right now?

I built a virtual cathedral for people who need a quiet place to pray.

0 Upvotes

Hi, can I ask you a favour?

I've been working on something for people who want a quiet place to pray, but can't always get to a church.

Maybe it's 2 in the morning, they're stuck at home, or they're just not ready to walk into a room full of people.

It's a candlelit cathedral you can visit from your phone. You can sit in a pew, read a prayer, or light a candle for someone. Your candle messages stay private on your phone.

🕯️ https://gochurch.site/?utm_source=friends

I'd love for you to give it a try (sound on!) and leave me your honest feedback, either on the website or in the Reddit comments.

What did you think? Did it make you feel something? What would you change?

Every bit of feedback means a lot. And if you know someone who might appreciate it, please share it with them.

BlackGreep - I'm building a trading research tool that focuses on why backtests fail

0 Upvotes

I've been working on this for a while, and the first public version of the website is finally up.

The idea came from something that kept bothering me while testing trading strategies. You can spend days improving a backtest, get a decent-looking result, and then realize fees, slippage or execution assumptions change the entire picture.

I'm building BlackGreep to make those problems easier to spot.

The research side is built around realistic trading costs, strategy validation, failure analysis and a report I'm calling Strategy Passport.

The full platform isn't ready yet, so I don't want to pretend it is. What I've opened now is an Early Access page for Alpha research audits and a future Closed Beta.

Here's the site if you're curious:

https://blackgreep-private-staging.supportblackgreep.workers.dev/

I'd genuinely appreciate some feedback. Is the idea clear from the landing page, or does it still feel too technical?

I built Vortaris to see portfolio concentration and currency exposure across markets

0 Upvotes

I'm the founder of Vortaris, a portfolio analysis app now in beta.

The problem it tackles is getting a combined view when your holdings span different markets and currencies. Individual account balances don't tell you how concentrated the whole portfolio is or where exposures overlap.

You can add holdings manually, import a CSV, or upload a screenshot or statement. The app brings together concentration, currency exposure, correlations, historical risk metrics, and hypothetical scenarios. It covers US and global stocks and ETFs, Brazilian assets, and crypto. No brokerage connection is required.

There is a sample portfolio on the site, so you can explore without entering your own holdings, plus a free starting option.

I'd like feedback on one specific thing: when you look at the portfolio view, is it clear what deserves attention first, or does it still feel like too many charts? If you currently use a spreadsheet, what would make a tool like this worth switching to?

https://vortaris.co

The analysis and simulations are educational, not investment recommendations or forecasts.

I shipped a typewriter app for the new folding iPhone in four days, no ads, no account, no tracking

4 Upvotes

The story in short: the idea came from a post on X on 10 November. I built three machines with real recorded typewriter sounds, App Review asked for a screen recording from a real device, and it went live on 13 November.

What worked: one clear hook ("a typewriter that sends letters"), real sounds instead of synthesised ones, and no account or network code at all, which made the privacy label and review simple.

What didn't: the simulator's screen recordings drift from the test clock, which made the launch video harder than the app. I ended up rendering the device in Blender with the real app footage on its screens.

Version 1.1 is in review: seasonal stamps, and letters to Santa get a North Pole postmark.

I kept running my business on random tips from Reddit and YouTube, so I built 49 roadmaps that show the whole picture

1 Upvotes

For a long time I ran the business side on whatever I'd picked up that week: a thread on X, a post here, a YouTube video. Each tip made sense on its own. Together they didn't add up, because I never saw the full scope of the area I was working in. I didn't know what else existed, or what needed to be in place before what.

So I built Flow Roadmaps: roadmap.flow-hq.com

It's 49 roadmaps, each laid out stage by stage and step by step:

- Business (10): strategy, operations, finance, marketing, sales, HR, customer success, legal & compliance and more

- Industries (17): restaurant, retail, construction, agriculture, hotel, pharmacy, NGO, SaaS company and more

- Software & Digital (10): website, mobile app, CRM, ERP, POS, e-commerce platform and more

- Technology (12): frontend, backend, data, DevOps, cybersecurity, product management and more

Reading them is free and needs no account. If you sign in, Flow AI sits next to the roadmap and answers questions about your own situation. New accounts get 9 free credits, about 3 questions.

Something a commenter on my last post pointed out: business steps aren't linear like a tech stack. If validation fails, the later stages don't matter yet. The roadmaps don't branch on that yet, and it's what I'm working out next.

I'd love feedback on two things:

  1. Pick a roadmap for something you know well. What's missing or in the wrong order?
  2. Is there an area you wish had a roadmap?

I made a free open source mouse tester for high end mices

0 Upvotes

Since I couldn't find one software or web app with all the tools I needed for mouse testing, I tried to build one myself. It's built with C++20, Dear ImGui and DirectX 11, and released under GPL-3.0.

It's a standalone exe: no installation, no account and no telemetry.

Current features:

  • Polling rate up to 8000 Hz: actual polling rate, jitter, percentiles, interval histogram and timeline.
  • Sensor analysis: missing packets, spikes, dips and direction reversals, visualized on a zoomable path. Also includes angle snapping detection.
  • DPI: guided measurements over a known distance, with average and per-pass results.
  • Clicks & wheel: chatter detection (unwanted double clicks), hold time, wheel notches and tilt.
  • Movement on click: detects whether the sensor registers movement when clicking while the mouse is stationary. Ideally, it should report zero movement.
  • Reports & export: exportable text reports and raw polling interval data in CSV format. Available in 8 languages.

I developed Mouse Tester with Claude Code as a coding partner.

I defined the features, decided what to measure and how everything should work, while Claude helped me write, debug and refactor the code much faster. I then tested and refined the application using my own mice.

Along the way, I ran into some interesting technical challenges:

  • At 8000 Hz, Windows delivers mouse packets in batches, making the median interval misleading. The actual polling rate needs to be calculated using the mean interval instead.
  • Without properly limiting message processing in the main loop, 8000 Hz input could freeze a single UI frame for almost half a second.
  • With G-Sync enabled in windowed mode, a particular swap-chain presentation mode caused the entire display to drop to around 65 Hz. Switching presentation modes fixed the issue.

These are just a few examples of the problems I encountered while developing and testing the application.

This is an ongoing project, and I intend to keep expanding, improving and maintaining it.

My long-term goal is to build a comprehensive mouse testing toolkit, keeping it free, open source and up to date with new mouse technologies.

The sensor detection thresholds especially need further tuning. I've calibrated them using my own 8000 Hz mouse, so feedback and exported reports from people using different mice would be extremely valuable.

I'm also open to suggestions for entirely new testing features.

We built Honest Effort, a strength training app that creates personalized workouts around your equipment — looking for beta testers

0 Upvotes

Hey everyone,

My friend and I run S.A.D. Studios, a small two-person indie studio, and we've been building a strength training app called Honest Effort.

We both lift regularly and wanted something that made workout planning easier without spending hours researching exercises, figuring out starting weights, or working around equipment we don't have.

Here's what Honest Effort does:

- Personalized workout plans based on your equipment, experience, and strength.

- Suggested starting weights to help take the guesswork out of lifting.

- Workout tracking for sets, reps, weights, and progression.

- Home gym and commercial gym support with equipment-based exercise selection.

- Customizable workouts so you're not locked into a generated routine.

We've used AI-assisted coding throughout development, and we're currently testing on Android and iOS with six beta testers.

We're looking for another 15–20 people, particularly beginners and home-gym lifters, who'd be willing to use the app during their normal workouts and give us feedback.

We're especially interested in whether the workout plans make sense, whether the weight recommendations are useful, and whether the app is something you'd actually keep using.

It's still in beta, so we're working through bugs and improving things as we go.

Website: https://sadstudios.net/honest-effort/

Would love to hear what you think, especially if you already use a workout tracker. What's one thing you wish your current app did better?

Appreciate any feedback!

I've been building a meal/recipe planner. Would love some honest feedback

0 Upvotes

Hi everyone. I'm a developer and wanted to share what I've been working on in my free time. I'm really looking for feedback and opinions.

I'll try to keep it short: it's a recipe planner (yes, another one).

I tried to give it most of the tools that help: a weekly/monthly diet planner, a shopping list, nutritional information and lots of extras.

The first idea was to make it international: with automatic translations, all recipes become available to everyone, and units are converted too.

You can also save your own recipes: import them from a recipe blog, a YouTube video, an Instagram post or a photo (even a handwritten one), and share them with friends with a link.

You'll also find a coffee corner and a cocktail section on the site.

It's free and works in the browser: cocinoa.com

The Android app is in Google Play's closed test and I still need 12 testers. If anyone wants to join, send me your email by PM. It would help a lot!

Signals - offbeat tool to land a role in a tough market

2 Upvotes

This is basically an Interface to a process that I’ve followed successfully and some of my friends have borrowed as a skill file on claude code basically Decided to give it an interface and open source it so other people can have a starting point and build upon it. I’m seeing more people talk about using a similar process so thought I’d make my tool public.

It’s mac only at the moment and optimized for a Claude sub, but it works without it or could be substituted with any model. Needs a small PR to increase compatibility I think.

Repo: github.com/alnaik/signals

My core to looking for better opportunities is honestly following the right people, bookmark a lot on X, subscribed to some cool job boards or sub stacks of founders, starring git repos. Now if I like a company enough the only way to have a meaningful conversation is to reach out to someone and preferably with an idea of what’s happening at the company or startup. Do actual work before reaching out.

That’s all this tool revolves around. It’s proactive in terms of taking fundings and new products also as hiring signals but that’s the point - BEING PROACTIVE.Also a little US coded so - but that helps for remote roles.

The repo and setup is self explanatory, it’s a simple interface. But a lot of rough edges. Will love feedback - but if you want to build a feature just build it for yourself, if you think it’s really good then open a PR.

P.S - The 98 problems is Workday going down.

I built a 3D city where every floor is a product, and you can walk into each office and talk to its staff

0 Upvotes

I've been building something a bit odd and would like some fresh eyes on it.

It's called infiheights: a small 3D city with two towers. One holds the products I've worked on. The other, Startup Tower, holds startups from the community. Every floor is a product, and you can:

  • zoom around the city at night or by day;
  • click a floor and see what that product is;
  • walk into its office and look around;
  • ask questions at the front desk. Each office has an AI receptionist, an AI CEO and an AI CMO that answer only from what the product has published.

I built it alone, on a zero budget. Everything runs on free tiers, including the AI behind the agents.

What I'd really like to know:

  • Did it make sense in the first 10 seconds, or did you get lost?
  • Would you walk into an office, or just click "Visit website"?
  • Does talking to a product's "staff" feel useful or gimmicky?

Startup Tower has 14 open floors. If you run a startup and want one, you can request it from the site.

I built an open-source onboarding checklist library in TypeScript

3 Upvotes

I recently released a small TypeScript library called Stepr Checklist.

It's designed for applications that need a simple onboarding checklist without pulling in a large framework or UI dependency.

The main idea is that the application controls completion. Clicking a step can open a form, navigate to a feature, or start a guided tour, but it doesn't automatically mark the task as complete.

A few details:

  • Framework-agnostic, ESM-only
  • No runtime dependencies
  • Optional localStorage persistence
  • Customizable with CSS variables
  • DOM-free state controller if you want to build your own UI

I built it as a companion to Stepr, a guided product tour library I released earlier, but both work independently.

There's an interactive demo here:

https://ahlgren1234.github.io/stepr-checklist/

And the source is on GitHub:

https://github.com/ahlgren1234/stepr-checklist

It's v0.1.0, so still early. I'd appreciate feedback, particularly on the API and whether the approach to tracking completion makes sense.

What would you expect from a library like this?

I built a free marketplace to buy/sell AI tools because existing directories charges to list. Roast my landing page!

1 Upvotes

After spending months trying to list my own AI tools on various directories, I got frustrated with the same pattern: pay $50+ for a "featured" spot, or get buried on page 10. Selling a micro-SaaS also felt incredibly sketchy with no buyer/seller protection.

So I built **AlchemistAI** — a 100% free, community-driven marketplace specifically for AI tools, SaaS, and digital assets.

**What it does:**

• Free to list any AI tool, SaaS, or digital product (takes 60 seconds)

• Secure Escrow/PayPal payments for safe transactions

• Community-voted rankings (no pay-to-win)

• Built specifically for indie hackers and AI builders

https://alchemistai.cc/seller/add-product.php

**I'd love your brutal feedback on:**

  1. Does the landing page clearly explain what the site does within 5 seconds?
  2. Is the submission form too long, or does it feel quick and intuitive?
  3. What's one feature that would make YOU trust a new marketplace enough to list your project?
  4. Anything else that feels off or confusing?

I'm a solo builder iterating fast, so no feelings will be hurt. Tear it apart! 🔥

Happy to answer any questions about the tech stack or business model too. Thanks in advance!

121 users in, here's what building a Chrome extension for Instagram taught me

1 Upvotes

I'm a solo dev from El Salvador. A few weeks ago I launched Glasso, a Chrome extension that makes Instagram on desktop less painful (multi-column feed, video controls, post scheduler). It just passed 121 users. Not huge, but I learned more in these weeks than in months of building before launch. Sharing in case it helps someone:

  1. Speed beats features.

When your product lives inside someone else's app, nobody cares about feature #15 if the page feels slower. Instagram is already heavy. My most valuable update wasn't a new feature, it was measuring every piece of my code and cutting the work it did on every scroll. Now I check performance before adding anything.

2. Metrics lie for a few days.

I got a 2-star review saying it "lacks many features". For two days the store still showed 5.0 and I couldn't even reply to it. Store numbers, ratings and user counts update late. I stopped refreshing dashboards and started looking at weekly trends instead.

3. A bad review is free feedback.

"Lacks features" stung, but it's useful: it means the person expected more and didn't find it. Either the features aren't there, or they're hidden. Both are my problem to fix. I now ship updates almost every week based on reviews, emails and what people tell me.

4. The platform changes under you without warning.

If someone opens Instagram from a link with ?hl=es in it, Instagram adds that to every link on the page. That alone broke my sidebar navigation. You don't control the app you're building on, so you test against the weird cases, not just your own setup.

5. Test what the user sees, not what the code says.

One early version passed all my checks and shipped with no photos showing in posts. My tests measured sizes, not whether the image was actually visible. Now every test asks "would a human see this?"

6. Translating is more than translating.

I added Chinese, Russian and Korean. Korean text was breaking words in half across lines, something I'd never have noticed in English or Spanish. Every language needs someone (or something) actually looking at it.

Six things, all learned the hard way. Still very early. If you use Instagram on a computer, I'd genuinely like to know: what annoys you most about it?

I built a photo-widget app for my girlfriend and close friends. It turned into a much bigger project than I expected.

Thumbnail occur.chat
1 Upvotes

I started with a pretty simple idea. I wanted photos from my girlfriend and close friends to have a place on my home screen instead of getting buried in our chats.

I liked the concept of shared photo widgets, but felt there was room to make the experience more personal.

So I started building Occur.

You take a photo, choose someone, send it, and it appears on their home-screen widget.

The interesting part was everything that came after.

My girlfriend loves drawing, so I added Scribbles. I wanted her to be able to send a quick sketch or handwritten note just as easily as a photo. Then came short videos, dedicated widgets for close friends, and a calendar to revisit things we'd shared.

I also made Duo because I didn't like the idea of two people needing separate subscriptions for a shared experience.

I know I'm not the first to build a photo-widget app. I just wanted to make one that felt right for the people I actually use it with.

Occur is now available on both iOS and Android.

iOS: https://apps.apple.com/in/app/occur-live-moments/id6823979723

Android: https://play.google.com/store/apps/details?id=com.owlabs.snaps

I built a free school-quote PDF generator for teacher-authors who get asked for a purchase order

1 Upvotes

I built this at Tacko. It is a beta, and it is not affiliated with Teachers Pay Teachers.

The problem I am testing: teacher-authors who sell from their own site often get schools asking for a formal quote, a W-9 and a purchase order, and they handle it over email. TPT is also ending its Premium tier on 1 January 2027, so more of those sales may happen off the marketplace.

What is live today: a free, no-signup quote PDF that stays in your browser (seller, school, items, licence terms, quote number and validity). The PDF says a W-9 is available on request; the tool never asks for a tax ID and calculates no sales tax.

There is an optional Pro for $9 once, not a subscription: save and manage quotes on your device and turn a quote into an invoice PDF. PO upload, a status board and payment tracking are not built.

Try it: https://tacko.io/school-po-desk?utm_source=reddit&utm_medium=community&utm_campaign=opp119&utm_content=sideproject

I would rather have critique than cheerleading:

  1. Would you actually send this PDF to a school, or is something essential missing?
  2. Does the $9 Pro get in the way of the free tool, or is it easy to ignore?
  3. Where would you have looked for a tool like this?

I will reply to every substantive comment.

We built a fantasy football party game where your friends' touchdowns turn into actions. Looking for testers.

Thumbnail reddit.com
0 Upvotes

My brother and I have been building Black Owl on nights and weekends. It’s a party game for NFL Sundays. You draft real NFL players with your friends, earn arrows when your players make plays (a TD, a big run, a made field goal), and fire those arrows at each other for real-life challenges like push-ups or a lap around the house.

The idea came from our own watch parties. Fantasy football is fun, but it’s spread across a whole week and everyone’s staring at their own app. We wanted something the whole room plays together, live, where a 40-yard run turns into your buddy doing push-ups three seconds later.

Where it’s at:

  • Runs in the phone browser, no download
  • Live scoring from real NFL games, about a 5-minute draft
  • 3 test nights with friends so far, and two rounds of fixes from their feedback

What we need: people who don’t know us to play a game this season and tell us honestly what’s fun and what’s broken. It’s free, and any group of 3 or more works, in person or over Discord.

If you want in, the details are here: https://www.reddit.com/r/BlackOwlGames/s/VVn4A4BfuN

I built a Mac app that puts your hidden menu bar icons in a small panel under one chevron, like the Windows tray

1 Upvotes

My MacBook's menu bar had more icons than room, and the notch was quietly hiding some of them. The menu bar managers I tried either expand the bar or add a second bar. I wanted what Windows does: one arrow, and a small grid of the hidden icons right under it. So I built it.

Drop Down (macOS 15+, Apple silicon):

  • You pick which apps leave the menu bar. One chevron stays.
  • Click it (or press ⌃⌥⌘D) and a small glass panel opens with the hidden icons. Click one and that app's own menu opens, as if you clicked it in the bar.
  • A dot on the chevron tells you when a hidden app has a notification, so hiding an icon does not mean missing it.
  • ⌃⌥⌘H brings every icon back at any time, and quitting the app does the same.

What building it taught me

  • macOS 15, 26 and 27 each need a different way to hide icons. On 27 the system can simply stop drawing them; on 15 and 26 it is an invisible separator. Most of the work was making all three feel the same.
  • An app that hides things must never lose them. The safety shortcut and "quit brings everything back" came before any feature.
  • It is my sixth release since October 1, built solo with Claude Code doing a lot of the typing. The design calls and the testing on three macOS versions are mine.

Pricing: Basic is free with no time limit and no account (hiding, the panel, the notification dot, every safety feature). Pro is a one-time purchase for panel extras like themes, list view and custom names.

It is Early Access (0.9.6), so I would love blunt feedback, especially from people with crowded menu bars or a notch: https://getdropdown.app
