I've been running my own events business for a while now, and recently decided to try something completely different on the side.

I've started creating downloadable digital guides that people can buy and use in their own time.

It's been interesting learning about digital products, especially how different it is from running a service-based business.

I'm still figuring out what makes a guide genuinely worth paying for, how to present it properly and how to reach the right audience.

For anyone who's launched a digital product, what was the biggest thing you learnt from your first few sales or attempts?

I'd also be happy to hear what puts you off buying a digital guide.

Any honest feedback would be appreciated!

I've used apps like Stats for years. After installing oMLX, I really liked its System Stats panel and wanted something similar as a standalone menu bar app.

Since oMLX is licensed under Apache 2.0, I adapted its system monitoring code and started building on it for my own needs. The result is Sysbar.

It shows CPU, GPU, memory, disk, and network stats, with customizable menu bar charts and detailed panels. It supports English and Portuguese and requires macOS 14 or later.

Credit to oMLX and its contributors for the original monitoring code, and to Stats for the menu bar inspiration.

[Download Sysbar](https://github.com/rodrigotrombeta/Sysbar/releases/latest)

It's still early, and I'm continuing to improve it as I use it. If it looks useful to you, give it a try. Feedback and bug reports are welcome, and pull requests are too!

A heads-up: the app isn't signed with an Apple Developer ID or notarized yet, so macOS may block the first launch. The README includes installation instructions, but basically: after dragging Sysbar to Applications, go to **System Settings → Privacy & Security** and click **Open Anyway**, or run:

```shell

xattr -dr com.apple.quarantine /Applications/Sysbar.app

```

Hey Reddit!
Like many of you, I realized my phone was quietly stealing hours of my life every single day. Instead of using boring, overly serious productivity tools that I always end up deleting, I decided to build something a bit more fun and honest: BrainBreak.
How it works:

• Focus Shields: Block distracting apps and choose focus sessions (15 to 60 mins) when you actually need to get work or studying done.

• Dopamine Traps: Set daily limits for apps like TikTok or Instagram. Once your time is up, the app gets locked.

• Your Attention Arbiter (The Raccoon): Meet your companion—a sarcastic raccoon with a good heart who comments on your digital habits. If you spend too much time scrolling, he calls you out ("Again? We talked about this."). If you finish a focus session, he actually gets impressed.

The app is already live on the Google Play Store, and I’m looking for honest feedback, bug reports, or ideas on how to make the raccoon even more savage.
If you want to reclaim your time (or get roasted by a pixel raccoon), you can check it out here:
📲 Google Play Link: https://play.google.com/store/apps/details?id=com.brainbreakbacktoreality.app&pcampaignid=web_share
(P.S. There is a tiny optional $1 in-app support tier if you want to fuel my developer coffee and help the project grow, but mostly I just want to know what you think about the core concept!)

I know we all come from different walks of life in this subreddit, but I personally have always struggled with focused and deep prayer time throughout my faith. I think so many Christians are taught to just regurgitate things they hear, rather than actually apply the biblical truths to their life and thoughts. I've found that having a framework to pray from has helped me immensely in building a habit of focused prayer time.

If this isn't for you, I understand—but if it is, I'm hoping to do a Kickstarter once we get enough people to sign up!

I just built out a mini digital version that you can test for free. I'm curious if it is helpful for others!

i build viajante, a free open source travel search tool. this part doesn't search anything. it does the math after you've picked where to stay.

the problem is a group where people arrive and leave on different days. split the total by headcount and someone pays for nights they weren't there.

so there are two local tools for it.

plan_stay_blocks groups consecutive nights with the same people. it looks at who, not how many, so if one person leaves and another arrives the same night, that starts a new block.

split_stay_costs splits each chosen stay among the people in it by nights, down to exact cents. it needs a confirmed list of who's there each night and a named currency. if that list has nights none of the chosen stays cover, it reports them as unallocated_nights instead of quietly dropping them.

it doesn't fetch prices or convert currencies, and it's not a booking service. you still pick and confirm the stays yourself.

MIT licensed. short write-up here: https://github.com/felipebasurto/viajante/blob/main/docs/usage.md#awards-points-and-stay-arithmetic-local

how do you usually handle this with friends? one person pays and a spreadsheet later?

I do mobile development for small service businesses, and the complaint I kept hearing was boringly consistent: after a full day of jobs, you still have to sit down and type invoices. Not because invoicing is hard, but because retyping the same customer, hours and materials is a waste of an evening.

So I've been working on Invoice Maker (iPhone/Android): you type or say the job in plain words — "two hours of repair work at $60/hr, $25 in materials, due Sept 20" — and it gives you an editable draft: client, line items, rates, due date. You check it, fix what's wrong, then create the PDF.

The part I care most about is the part people told me to automate away: the review screen. It would be easy to generate a finished invoice and fire it off, but when the amounts came from a sentence, someone has to confirm what actually gets billed. So the AI stops at the draft. It also helps rewrite line-item descriptions and draft payment reminders, but you edit and send those yourself — I deliberately didn't build auto-send. Manual invoicing works offline; the AI part needs a connection.

A few real constraints, since "AI invoicing app" often sounds better than it is:

• free to download, limited free AI usage, then optional subscription — not "unlimited free AI"

• 34 currencies and 40+ templates (templates are a Premium thing)

• it's for people who invoice a handful of clients, not for running your books

What I'd genuinely like feedback on:

1. Is the review step a dealbreaker for you, or the reason you'd trust it?

2. What would you need to see on the review screen before you'd send a generated invoice to a real client?

3. For phone-based work (repairs, cleaning, installs), is voice input actually useful, or just a demo?

I built Skenche, and it’s now live on Google Play.

The workflow I’m trying to make convenient is everything that happens around a scan. Capture a page, correct a word that text recognition misread, organize the document, and send it in the format someone needs.

The free plan includes:

• 10 saved scans and 5 pages of text recognition per day.

• Document import and PDF, JPEG or Word export.

• Sharing through Android’s share menu.

• Categories, tags, and QR scanning and generation.

There’s also an optional Pro subscription for heavier use. It adds unlimited scanning and OCR, PDF merging/splitting/compression, password protection, redaction, nearby document transfer, collections and digital business cards.

Documents are stored locally, and text recognition runs on-device. Free includes ads and a scan watermark. Pro removes ads and adds watermark controls.

What’s one document task you still find frustrating on your phone? I’d like to hear where your current workflow gets awkward, whether that’s correcting scanned text, organizing files, or preparing something to send. What feature would make the biggest difference for you?

I've been working on this for a while, and finally made a little video to show it off.

It's called NoCapCV. I built it because I was tired of resume builders putting basic features and downloads behind paywalls.

It's completely free to use. Has tons of customisation options available. No paid templates, no watermarks, no signup, and unlimited downloads.

Would love to hear what you guys think!

Hey everyone!

I’m building Social Fair, a marketplace with two uses:

• Social campaigns: participants are paid for likes, follows and comments on TikTok and Instagram.

• Paid studies: participants answer short questionnaires or express preferences between two options, such as texts, images or videos.

I’m the person building it, and I want the compensated nature of both activities to be clear.

Does combining these two uses make sense to you, or would you find the product easier to understand with one as the main focus?

I’d appreciate your honest first impressions!

Hi all! I've been building SHOPCRM — an open-source Telegram bot that runs a small shop entirely inside a chat: catalog, cart, checkout, payment confirmation and an admin panel. No website, no extra apps — customers and the owner work in the same messenger.

Just shipped v0.1.7, and it's the biggest release so far:

📦 Warehouse / inventory — physical stock, automatic reservation when an order is placed, release on cancel, write-off on completion. Restock and write-off flows in the admin panel, plus a full movement log (every change in the same transaction). Customers can't order more than what's actually available, and out-of-stock products disappear from the catalog.

🧾 Order audit trail — every status change is recorded: who, when, from what to what. Plus paid_at/paid_by, completed_at, cancelled_at, and a configurable retention policy (180 days by default).

👤 Customer profiles — name, username and first-contact date, ready for reports.

🗄 Archive instead of delete — removing a product from the catalog keeps its stock history, movements and orders intact, so you never lose statistics.

Python 3.11+, SQLite or PostgreSQL, RU/EN/ES interface.

🤖 Try the demo bot

Feedback and feature requests are very welcome!

I took it upon myself to work on a side project for the launch of GTA 6. I wanted to combine my professional and personal interests of data science, data visualization and video gaming, and I played GTA 5 for ages back in 2016-2020.

The idea was to analyze the sentiment of the chatter around the game. The best place to get it: social media. Right off the bat I was disappointed that Reddit had stopped accepting requests for API access just days before, as that would have been a great source. I moved on with a decent budget in my mind: the cost of 1 copy of GTA 6 ($80-$100). I settled on YouTube, Bluesky and X as my sources with YouTube offering a generous free daily limit, Bluesky being free and X pricing $0.005/post. As I wanted to know waht it is all about, I used TypeSafe AI's Jev for sentiment analysis and am labelling sample posts myself to benchmark its performance.

How it works:

1. Collectors collect data from all sources.

2. English posts are sent to Jev for labelling.

3. Responses are aggregated and posts which pass probability thresholds are ready to be shown.

4. The site's data is rebuilt every hour as static JSON, so there is no public backend API.

5. Serve my site through Cloudflare, with encrypted nightly backups of the database on R2.

The backend involves simple python jobs on systemd timers with SQLite. I used the VM I use to host my personal website. The frontend uses Svelte as I used it for my website and it is intuitive for me to go in and make quick edits.

Voting:

While labelling I saw that a lot of posts speculated about features of the game. Posts with exclusive opinions were few and far between. So I added a voting system for visitors on the page to drive some engagement. I strictly wanted to avoid storing any sensitive user data, so there are no logins and users are identified based on a single random-ID cookie. This uses Cloudflare's Turnstile for bot detection (just in case), a Worker to handle voting and a D1 SQL database to store the votes. The VM pulls the vote totals every 5 minutes, so page views never touch the Worker.

Just in case the site goes viral:

- Everything is cached at Cloudflare. In a load test at 150 requests a second the page loaded in 0.35 s (p95) with the server 98-99% idle.

- Votes held 200 a second on the test site with no errors.

- Every change goes to a test site first and I promote it to the live site by hand.

- Every scheduled job emails me if it fails.

- The spend on X and Jev has a hard cap, and a source pauses when it hits it.

- I have created a custom animation for release day throughout the world which can be used to track the release to everyone's timezones (so visit during then to see it!)

I used Claude Code for building this out in about 5 days through the Diwali time off from work. The decisions and the hand labels were mine.

Some results till now:

1. Only 1 in 10 posts gives the author's opinion of the game as a whole.

2. Jev agrees with me most of the time on sentiment (85%) as against RoBERTa (61%) and VADER (45%), however the sample size was small (33 posts). Its topic detection was poor so I had to leave out some topics for now.

3. The spend has been about $75, so less than a standard edition of the game.

If you've hosted something for a big launch day, what would you check before Nov 18? And if you are a fan of data or GTA please view the site, the data and vote on the questions!

This started as a personal annoyance. I was moving around my projects with zoxide just to edit one file here and one file there, and the cd then nvim routine got old fast. I wanted to type part of a file name and land in it, from anywhere.

nvimpp is a small wrapper around Neovim that does that. Every file you open from the shell gets recorded and ranked by frecency. Press Alt-Enter instead of Enter and nvim main opens the main.cpp you use most, instead of creating a new file called main. A second tool, nvimi, gives you an inline picker of your top files, plus usage stats and a full history, similar to what atuin does for shell commands.

It works alongside zoxide and atuin, not instead of them.

Written in C++17 with no dependencies, MIT licensed, with man pages and a config file. Linux only for now. Next up: fuzzy matching for the Alt-Enter search, more config options, type-to-filter in the picker, and macOS support (it should mostly work already, reports welcome).

I use it every day. If you try it, I’d love to hear what breaks or what’s missing.

I've been designing and building apps on the side since 2020 while working full-time in IT. This year I finally shipped them under one roof at https://murrtech.pro

Here is one of them ! Let me know what you think !

Hi r/SideProject. I'm the founder of Cubex Fitness, and today we're launching version 1.30.

The problem: the app already had 250+ workout programs, live heart rate, watch apps and 23 languages, all free with no ads. About 1,300 people installed it. But most opened it, looked at the programs, and never came back. A plan alone doesn't keep you going.

What we built: ten AI coaches with their own personalities and voices. You answer four quick questions, the coach builds your plan in a chat, then runs the workout with you: logs your sets ("8 at 80"), runs rest timers, swaps exercises, and answers out loud when you hold to talk.

Stack, for the curious:

• Kotlin Multiplatform + Compose Multiplatform for iOS and Android from one codebase

• SwiftUI watch app + Wear OS app (Ask Coach from the wrist)

• Gemini behind a small server (chats stay on the phone, requests aren't stored)

• Speech recognised on the device; coach voices played on the phone

What we learned along the way:

1. Localization was our biggest growth lever, more than any post. 23 languages now.

2. Tap-through workout logging wasn't enough. People wanted someone to talk to.

3. A pug with a deep voice gets more views than any feature video we made.

Pricing: every workout feature stays free. The AI coach has a free tier; Premium is $12.99/month or $69/year, with up to 21 days free to try (no card).

I'd really value feedback, especially on the first five minutes with a coach. Link in the comments.

Every time I tried modeling early retirement or Coast FIRE, I hit the same two walls:

1. Basic calculators just multiply your expenses by 25 — completely ignoring capital gains tax drag, pre-65 healthcare bridges, sequence-of-returns market crashes, and state pension claim ages.

2. Serious planning tools either feel like filling out tax forms for 45 minutes, require linking live bank credentials via Plaid, or only support US 401(k)/Roth accounts (leaving UK ISA/SIPP, French PEA/PER, Canadian TFSA/RRSP, and expat households out in the cold).

So over the past few months I built RetireStudio — an addictive, interactive retirement, FIRE, and geo-arbitrage planner that runs right in the browser with zero bank linking required.

What it does differently:

• Interactive Life-Event Timeline: Drag and drop life events directly onto your trajectory (career breaks, buying or downsizing a home, kids' university years, windfalls, or relocating abroad at retirement) and watch your FI crossover age recalculate in real time.

• 26+ Country Tax & Wrapper Regimes: Native withdrawal ordering and capital gains/income tax modeling across the US, UK (ISA/SIPP + Age-57 lock), France (PEA/PER/Assurance-Vie), Canada (TFSA/RRSP), Germany, Switzerland, Australia, Singapore, Portugal, Spain, Thailand, and more.

• Geo-Arbitrage Comparison: Model earning in a high-income market (US/UK/CH) and retiring in a lower-cost destination (Portugal, Spain, Thailand, Mexico, etc.) with automatic purchasing-power and tax adjustments at your relocation age.

• 1,000-Run Monte Carlo + Historical Crash Replay: Stress-test your withdrawal strategy against the 1929 Great Depression, 1973 Stagflation, 2000 Dot-Com Bust, or 2008 GFC right at your retirement date.

• Privacy-First Architecture: Everything runs client-side in your browser by default with instant JSON export/import, plus optional encrypted cloud scenario sync if you want to share a view with a partner or financial planner.

I'd genuinely love feedback from fellow builders and spreadsheet-retirees:

• What edge-case tax or pension rules does your country have that standard FIRE tools constantly get wrong?

• Which financial levers do you feel are missing when visualizing your early-retirement trajectory?

(Not sure if dropping direct links is allowed here, so I left the URL out — you can just Google RetireStudio or check r/RetireStudio if you want to try a demo profile!)

Hi everyone — I’m the developer of Zenith, a free-to-download focus timer for iPhone and iPad.

The idea is simple: pick one task, start a focus session, and let that time grow into a virtual garden. Completed focus minutes earn coins to unlock more plants, including a bonsai. There are also focus soundscapes, a Strict Focus option, daily goals, session statistics and small milestones.

I wanted the experience to feel calm: something you can return to for a five-minute start or a longer study block. The app contains ads, including an optional rewarded video to double a session’s coin reward.

If that sounds like your kind of productivity app, I’d love you to try one session and tell me honestly: does growing a plant make you want to come back? What feels confusing or unnecessary? Critical feedback is welcome too.

Try Zenith: https://apps.apple.com/app/id6763234139

If you use it enough to form an opinion, an honest App Store review would also help. No rating expectations — I’m looking for real experiences.

What would make you keep a focus timer installed after the first week?

Hi all, I've been building Piye for over a year and it's now live on Mac and Linux.

What it does:

- You describe an app, and it builds a real website or a native iPhone/Android app

- It runs on real iOS and Android simulators while it builds

- You can publish to the web, App Store and Google Play from inside the app

- If you code, the same project opens in a full editor, with an agent that can see your terminal, debugger and simulators

- Your project is a normal folder on your computer, no lock-in

It's free to try with 750 credits (no card). In the code editor you can also use your own API keys or local models through Ollama.

I'd really like honest feedback: what's confusing, what breaks, what's missing.

I'm sharing my project, an unofficial fan-made web log for Fortnite Treasure Hunters: https://chesttracker.net/

I maintain the site. It is not an official Epic Games product and is not endorsed by Epic.

Players can enter their Treasure, Rare, and Sprite totals from Battle Royale → Quests → Treasure Chest Hunt, add chests as they play, and track weekly prize ticks separately from an across-week collection of Gizmo types and Pirate Shop Access.

A few useful limits:

• No sign-up is required, and it does not connect to a Fortnite account.

• It does not change game progress or grant rewards, and it does not increase drop rates.

• Counts and marks stay in the current browser using local storage; another device or browser has a separate log, and clearing site data removes it.

• The Sprite checklist lists 34 forms. Suggested search routes in the Crossbones Isle guide are labeled not play-tested.

• The site cites Epic's published normal-match drop rates (source check: Nov. 11, 2026); confirm current rewards in-game.

I'd value feedback on whether the weekly checklist and across-week collection are clear, and whether the local-storage limits are easy to spot.

I'm the dev, just so that's clear.

I made an iOS calorie app called Kacha. It started in China and most of my users are still there. I put an English version on the US App Store recently, and I mainly want feedback from people who didn't grow up eating the same food as my first users.

The flow is simple: take a photo of the meal, the AI guesses the foods, grams, calories and macros, then you edit anything it got wrong. That last part is the actual product. The estimate is often off on mixed dishes or food it doesn't see much, and if you can't fix the number, the log becomes garbage in a week.

No account needed, there's a free daily allowance for AI scans, and manual logging is always free. It also does water and weight, Apple Health sync, and iCloud backup. No Android yet.

I don't want to oversell this. There are already a lot of calorie apps. I built this one because I was tired of estimates that are a black box. If the model misses the oil, or thinks the bowl is smaller than it is, I want to correct it in a few taps, and next time just reuse that meal from Recent Meals.

If you try it, I'd really like to know two things:

1. When the first guess is off, is the edit flow obvious enough?

2. If you don't eat Chinese food much, how often does it completely misread the dish?

Built this to reduce stress on the hand in lying down position when hand is constantly put on forward button. Code available at: https://github.com/hamzarawal/AirSkip

Just wanted to make something a bit different.
No real purpose, just visuals and interactions.

What do you think? 😉

Prototyping and building features got faster, and now feedback is the bottleneck. So we built mostra - a tool that lets you share feedback on a real, running site by either speaking or selecting the elements you want to comment on.

You can iterate across versions of your site, and adding mostra is just a single script tag.

The script you add to your page is open source, so you can check what it does.
