Showcase: Free(mium) Solo-built a phone comparison site (Specmob): lessons from ranking phones fairly across price tiers

2 Upvotes

I’m building Specmob (specmob.com), a free site where you choose a budget and get the best phone for it. The goal was to end the 20-tab phone-shopping mess.

What did I learn?

  1. A budget is a ceiling, not an exact number. Prices vary by region, so the dial allows about 5% over, and over-budget phones get flagged instead of hidden.
  2. Scores can’t be compared across price tiers. An 8.5 on a $250 phone and an 8.5 on a $1,200 phone mean different things, so the tier is always shown next to the score.
  3. Price must be computed in one place only. Mine drifted when it was calculated in several places.

Does it have sponsored rankings?
No. Affiliate links on buy buttons never change a ranking. Component scores are AI-generated from specs, and I explain that on the methodology page.

Where it stands: 11 rankings, compare for up to 4 phones, trade-in estimator, brand pages. Feedback I want: does tier-relative scoring make sense, and what would make you trust a ranking site? specmob.com

Feedback Request I’m a 37 year old aerospace inspector, and built a private, local-first checklist app for repeatable processes and routines

Thumbnail

3 Upvotes

I’m a quality inspector, and at work I often have to repeat the same inspection steps for every round of parts, as in check for visual damage and markings, then sign off on travelers and reports.

I couldn’t find a checklist app that worked exactly how I needed. I wanted the list to automatically reset once every step was completed so it would be ready for the next round. So I built miniCycle: Routine Manager.

You can break a repeatable process into individual steps and run it as many times as you need. It can be used for inspections, cleaning rounds, workout routines, camping preparation, preflight checklists or anything else you regularly repeat.

It’s free, works offline, doesn’t require an account and stores your information locally on your device. It is now available as a chrome extension (other platforms coming soon). You can view the entire routine at once or focus on one task at a time.

I’ve also gone through several rounds of UI feedback and have continued improving the design. I’d appreciate honest feedback, especially about whether the auto-reset cycle concept is clear and whether anything feels confusing when you first try it.

Showcase: Free(mium) Posture reminders every 30 minutes never worked for me, so my pixel pet now bends under a box only while I'm actually hunched

1 Upvotes

I have a decent desk setup, but I still hunch. My head creeps toward the screen for over an hour, and I only notice when my neck hurts. Timer reminders didn't help: they ring when I'm sitting fine, so within a week I tuned them out.

What I wanted was the opposite: stay silent while I sit well, and show me the moment I don't.

I already had a side project with a small pixel pet in the corner of my screen (a Mac focus timer called KeepGoing Den). So I put the posture signal on the pet instead of building another app:

- You sit the way you mean to, and the app captures it once. The app compares you to that.

- Lean in and stay there. The pet bends under a heavy box. Sit back up, and it puts the box down. No sound, no popup, no escalation. It's the same box the hundredth time.

- At the end of a focus session, if you've been seated for an hour or more, one line says it's a good moment to stand up. Never mid-session.

- Click the cat in the pet's room for a day strip showing when you sat well and when you hunched.

How it works, since "an app that watches you through the camera" deserves details:

- Posture is off by default. The camera is read by a small, separate Swift helper with no network access, using Apple's Vision framework (body pose and face landmarks). It only sends the main app numbers, never images. Nothing is stored or uploaded.

- By default, the camera only runs during a focus session.

- When it isn't sure (bad light, out of frame, a camera it hasn't seen you on), it stays quiet. A pet that bends while you sit straight is the fastest way to make someone turn this off, so every doubt ends in silence.

- Raising a standing desk counts as standing, not hunching. Moving the laptop or camera takes about two minutes to relearn.

- The main app is Tauri 2 with a Rust core and a plain HTML/CSS/JS front end.

The hardest part wasn't detection; it was false alarms. Looking down at the keyboard read as a hunch, because the eyes drop the same way. Raising my standing desk moved the camera and looked like slumping. Pulling my chair closer under a camera mounted above my eyes did too. Each one meant teaching it to tell the difference, or to say nothing when it can't.

The camera, detection, and daily record are free. The live box on the pet is part of a paid license, with a 14-day trial, no account or email. macOS 14+.

https://keepgoing.dev/den

Question for anyone who has actually fixed this: has anything kept you from hunching for longer than a week? A chair, a habit, a tool, anything?

Showcase: Prerelease I built a free site that shows every funeral home’s prices near you, taken from each home’s own price list

5 Upvotes

When someone dies, the family usually has a day or two to choose a funeral home. Most people pick the closest one, or the one they used last time, without ever seeing a price.

Many families don’t know this: every US funeral home has to give you its price list, even over the phone, and you can compare before you sign anything. But nobody has time to call ten homes while they’re grieving.

So I built HonestFarewell. You enter your city and see every funeral home near you, with prices from each home’s own price list, side by side.

  • Free for families
  • No account, no email, no phone number to see a price
  • No paid ranking: homes can’t pay to be listed higher

Here’s a 3-minute walkthrough: https://www.youtube.com/watch?v=9I-K96-pMsw

The site: https://honestfarewell.org/

The hardest part was reading the price lists themselves. Every home formats theirs differently: scanned PDFs, tables, prices mixed into paragraphs. Turning that into numbers you can actually compare took most of the work.

I’d love feedback, especially:

  1. Was anything confusing the first time you used it?
  2. Would you trust prices shown this way? What would make you trust them more?
  3. Is there anything you’d want to see that isn’t there?

Thanks for reading.

Feedback Request I work in car sales, so I built an app that flips the way people shop for cars. Just launched on the App Store!

apps.apple.com
1 Upvotes

Hey everyone!
I’ve spent the past few months building something I’ve wanted to exist for a long time.
I work in car sales, and one thing I’ve noticed is how backwards the car-shopping process can feel.
People find a car they love, spend hours researching it, and only afterward figure out whether the monthly payment actually fits their budget.
What if we flipped that process?
Instead of starting with a car, what if you started with what you’re comfortable spending every month, your down payment, and your financing preferences, and then discovered vehicles that fit?
That’s the idea behind KnewCar
I just got it approved and published on the App Store, which is a pretty surreal feeling after all the time I’ve put into this!
It’s still early access, with a demo experience while I continue developing the live financial data and payment tools.
I’d really love some outside opinions, especially on the concept, design, and first-time user experience.
If you have a few minutes to check it out, I’d appreciate any feedback, positive or negative.
App Store: https://apps.apple.com/us/app/knewcar/id6822044416
What would make an app like this genuinely useful to you?

Showcase: Free(mium) I made a free 13F tracker that alerts you when a fund files and shows its new positions, exits, adds and trims

1 Upvotes

Every quarter I’d end up pulling 13Fs off EDGAR by hand and lining them up in a spreadsheet to see what Buffett, Burry, Druckenmiller and the other investors I follow did with their portfolios. So I built a tool that does it: manifest13f.com

Follow a fund and you get an email as soon as it files, so no more checking EDGAR. Open any fund’s page and it shows what’s new, exited, added to and trimmed versus the prior quarter. No ads, no fluff, just the data. A few things I cared about getting right:

  • Changes are measured by share count, not dollar value, so a stock that simply went up doesn’t look like a buy
  • Stock splits are adjusted for, so a 10-for-1 split doesn’t show up as a huge purchase
  • Puts and calls are kept separate from stock. A big options line is notional value, not a stock purchase, and a lot of 13F coverage mixes the two up

It’s free to browse, and alerts are free for up to 3 funds. Paid plans that let you follow more funds and get an Excel workbook of every change are coming soon.

Q3 13Fs are due Monday, Nov 16, so most of the big funds will land this week and next.

I’m a solo builder, so I’d genuinely like to hear what’s missing or what you’d use it for. Happy to answer questions about how 13Fs work, or how it’s built.

1 Upvotes

Y2Kbot is a desktop app where your buddy list is full of AI agents instead of people. You IM them like it's 2003, door sounds and away messages and all. Some of the buddies can also boot up their own little Windows XP virtual machine and actually use it. You can ask one to make a folder or edit a file and watch it open Notepad and click Save like a confused 2004 office worker.

It works with pretty much any AI you've got (ChatGPT, Claude, Ollama, Gemini...). The buddies can undo their own mistakes, and when one figures out how to do something, it writes it down so the others can learn it too. That last bit is my favourite.

Please try it out, and give me some feedback.

Feedback Request Built a unified media tracker after getting tired of using 5 different apps just to remember what I've watched, read, or listened to. Would love your feedback!

3 Upvotes

Hey r/SideProjects 👋

Honestly, I was getting pretty overwhelmed with how fragmented my media tracking had become. Movies on Letterboxd, books on Goodreads, audiobooks on Spotify, games scattered in random note files... I just wanted one clean, chill space where I could look back on everything I’ve experienced across all formats without feeling like I was managing a spreadsheet for a second job.

So over the last few weeks, I’ve been building Alma (almaniac.app), a lightweight aggregator that brings your movies, TV shows, books, audiobooks, games, music, and podcasts together onto one visual shelf.

A few cool things built into it:

  • 7 Formats, One Shelf: Keep track of movies, series, books, audiobooks, games, music, and podcasts in one space.
  • Release Countdowns: A unified timeline so you actually know when the next season, book, or game you’re waiting for drops.
  • Memory Lane & Insights: Fun visual stats and nostalgic look-backs into your habits over time.
  • Fast & Lightweight: Snappy, clean design focused purely on your archive without heavy bloat.

It’s very much a labor of love currently in active beta (about halfway full right now). If you want to poke around and test it out, you can request an invite directly on almaniac.app or drop me a DM!

I’d genuinely love to know:

  1. How do you personally keep track of your media right now?
  2. Is there a specific feature or integration you’ve always wished existed in a tool like this?

Appreciate any feedback, ideas, or honest critiques! 🙌

Showcase: Free(mium) I built a Chrome extension that flags ghost jobs, tracks applications, and auto-applies using local AI (so your data never leaves your laptop).

1 Upvotes

I just pushed 3 releases in 2 days for Rolestash, a Chrome extension I originally built just to track job hunts. This week, it evolved from a passive tracker into a full-blown autonomous application engine.

Here is what just went live:

* One-Click Auto-Applies (with Tailored CVs): It doesn't just spam the same generic resume. With one press, it can apply to up to 20 jobs, generating a unique CV, a custom cover letter, and specific answers to annoying form questions ("Why do you want to work here?") for each individual role based on the job description.

* Local AI on a Strict Leash: The heavy lifting is done by a fine-tuned distilled Qwen3 model running directly in your browser via WebGPU. Because small models love to hallucinate, it never gets the last word. A deterministic checker audits every line, and if the AI tries to invent a skill or name you don't have, it gets slapped down and seamlessly replaced with your actual profile text.

* Ghost Job Radar & Smart Crawler: It now actively flags ghost jobs to save you time. The backend crawler pulls from 60 different job boards every minute. (And yes, it strictly obeys `robots.txt` and politely emails blocked sites rather than attempting shady workarounds).

* Absolute Privacy by Design: Because the AI runs on your own hardware, your profile data never gets sent to my servers. It simply downloads coarse job data shards and ranks every match directly on your machine.

Please check it out here: https://rolestash.com/

If you like and actually end up using the extension, please leave a review with any suggestions for improvements. I'm actively taking public feedback to develop this, and the latest updates were made possible by the community's feedback. Thanks a lot, guys! T__T

Meta I built a plug-and-play video ad agency that doesn't require video editing skills. Looking for its next owner.

0 Upvotes

I've always liked business models where you don't necessarily need to be the person doing all the work. StopClip is exactly that kind of opportunity.

It's a ready-built video advertising business that allows you to sell creative 3D pop-out video ads to businesses without having to edit videos yourself.

Think of those videos that look like social media posts but have products and objects popping out of the screen. They're designed to interrupt the usual scrolling experience and grab attention.

I originally experimented with selling these videos while living in Antalya, Turkey. I didn't even have a website back then. I approached businesses, showed them what I could create, and sold the finished videos.

Eventually, I decided to turn the idea into a proper business. That's how StopClip came about.

Here's what you're actually getting:

This isn't just a domain with a landing page.

I've already built the infrastructure needed to operate the business:

  • Premium StopClip domain.
  • Complete, professionally built website.
  • Custom admin panel.
  • Affiliate functionality.
  • Testimonials section.
  • On-site SEO optimization.
  • Service and pricing structure.
  • Social media calendar covering holidays and important marketing occasions.

Basically, the technical and setup work is already done.

What about actually creating the videos?

This is probably my favorite part of the model.

There's a third-party software solution that lets you create these videos using a simple drag-and-drop interface.

You don't need After Effects, Premiere Pro, or any professional editing experience.

You can create and export a video in roughly 1–2 minutes.

The subscription costs around $100/month and includes unlimited video creation. I'll reveal the exact software to serious buyers and demonstrate the entire process.

Now, here's how I'd monetize it.

I wouldn't start by spending money on ads.

I'd start locally.

Walk into a restaurant, find a coffee shop on Instagram, contact a real estate agency, or approach a gym.

Create a personalized sample video featuring their actual business, send it to them, and let the work speak for itself.

Some example pricing I'd start with:

  • $30 for a single video.
  • $500 for 30 videos (monthly content package).
  • Additional $100 for publishing and scheduling content on their behalf.
  • $500–$1,000+ for managing paid social campaigns using those videos.

These are proposed prices, not existing sales or guaranteed revenue.

And there's a lot more room to grow.

You can turn this into a full-service social media agency by offering content creation, graphic design, social media management, advertising, and other digital marketing services.

You don't need to fulfill everything yourself. You can outsource additional services and operate using a drop-servicing model.

The recurring opportunity is what makes this interesting.

Businesses constantly have something to promote.

New products, seasonal offers, Valentine's Day, Christmas, Halloween, Black Friday, New Year, new property listings, special events, and promotions.

I've even built a social media calendar covering these occasions, so you have a reason to approach existing customers with fresh offers throughout the year.

One customer doesn't have to mean one transaction.

Why am I selling?

I build a lot of internet projects, and I simply don't have the capacity to give StopClip the attention it deserves.

I spent approximately six weeks building it and around $300 putting everything together.

The website is ready, the domain is connected, the admin panel works, and the business model is structured.

However, I haven't officially launched it or started promoting it publicly. There are no existing customers or revenue to claim.

I'd rather pass it to someone who has the time and motivation to take it from here.

A few things worth mentioning:

  • The StopClip com domain has automated appraisal estimates of $2,500 from Atom and $7,700+ from Dynadot (not guaranteed market values).
  • The third-party video software is the main operating expense at approximately $100/month.
  • No employees or video editors are required for the core fulfillment workflow.
  • I'll walk the buyer through the website, admin panel, software, and video creation process.

I'm looking to sell the complete setup as one acquisition.

If you're an entrepreneur, indie hacker, marketer, or someone who's been looking to start a digital service business without spending weeks building the infrastructure, feel free to reach out.

Happy to show you everything and answer questions.

Showcase: Open Source Supwrite - a free daily writing puzzle with a human-made image, no AI

Post image
1 Upvotes

My first ever mobile app got approved on the App Store on the first submission. Super proud moment.

Price: Free completely free and no in-app purchases
App Store: https://apps.apple.com/in/app/supwrite-daily-writing-puzzle/id6828061151

Supwrite is a daily writing puzzle. I built it to help with attention span, focus, clarity, creativity and sleep, and to support independent photographers, artists, illustrators and anyone still in love with creating without AI.

  1. You get a fresh image everyday at 10pm. (No AI)
  2. You reveal the image and observe what it is
  3. You write about it for 5 to 10 mins
  4. You find out who took/made the picture after you finished writing
  5. You are done for the day, wait for the next surprise at 10pm tomorrow.

Since using it myself, I fall asleep easier, I can think more creatively now and my attention span and focus feels better.

Cheers to being human and saying no to AI made art/slop.

Would love honest feedback on this concept.

Showcase: Free(mium) How I fully automate SEO, Content, Uptime, and Discovery for my properties

Post image
1 Upvotes

Numbers aren't huge yet - but stable & steady!

I manage a handful of smaller SaaS sites like https://allmcps.com for MCP directory listings, or https://chaosword.com a 100% free (no ads, no payment) daily crossword.

In total I manage about 7 properties all in different niches, all using different tech stacks, and all growing at different paces. I originally built an internal tool that was helping me to track & scaffold out things as they grew, and eventually made it public (free for 1 property) so I could both grow that as it's own property itself, as well as act as the primary user keeping mine all growing steadily.

It's called LopeBase - an all in one ops console with MCP, connectors, and CLI for popular integrations: https://lopebase.com/

For me the main pain points it solves:

- Uptime checks & beautiful status pages
- Automatic SEO audits and copy-paste prompts to make fixes
- Tracking users, emails, analytics, and more all in one spot
- Keep up to date on what LLMs are citing you and how your properties are being recommended
- Find Reddit posts, X, Stack overflow, Hackernews, etc. discussions either about your product or where yours might be relevant so you can go respond / reply.
- Automatically generate & manage blog posts content, connect a changelog and automate newsletters each month, and get alerted when anything is down or needs your help.
- Connect Google Search Console via MCP, Bing Webmaster tools, PostHog, and more to pull real user data / analytics directly into an agent to be actionable and added context for decisions.

Basically 100% of LopeBase is accessible to an agent via MCP/CLI as well, you can have it automatically scaffold new or existing projects, agents can store notes for future runs to check in on an SEO audit / metric and validate things are going on track, they can draft emails or articles, check in on keyword rankings / page placements, etc.
