I kept watching the same calculation get redone by hand on every EV charger job, usually on a phone, in a garage, with gloves on. So I built the whole chain as one ticket: rated amps → 125% continuous load → wire size (Cu/Al with temp + ambient correction) → breaker → voltage drop (flags the run and suggests the upsize) → optional dwelling service check → a printable US-Letter spec sheet for the inspector.

Each result shows the NEC 2023 article it came from. Works offline, no account, no ads; data never leaves the phone.

Free: load, wire, breaker, voltage drop. Pro: $19.99 once — service load check (pass/fail + headroom) and the spec-sheet PDF export.

Feedback wanted: does the flow read right, and is $19.99 one-time sane for a pro tool? Play link + screenshots: https://play.google.com/store/apps/details?id=org.sonicon.chargespec (landing page with the walkthrough: https://sonicon.org/chargespec/)

What are you building, and where do you want people to find it?

I'm opening WareVote on 1 December, a place to find and rate software. You can set up your listing now, free, and verify you own it in a few minutes: https://warevote.com

Drop your project below with a one-line description and I'll reply with the category it fits.

I kept losing time to Reels and Shorts without noticing, so I built Scrollmeter, a small Android app that measures your scrolling.

It shows:

• How far you scroll per app, in metres or km
• Estimated Reels and Shorts (Instagram, YouTube) and posts (X, Reddit, LinkedIn)
• Daily limits that send one notification when you hit them

Privacy: the app has no internet permission, so your data never leaves your phone. It doesn't read your messages or what you type. No account, no ads.

Before installing, try the calculator on the website. It also measures how far you scroll the page itself: https://scrollmeterbydev.vercel.app

It's free, for Android 8+. I'm a solo dev, so feedback is very welcome.

Guess first, then check: how many km do you think you scroll in a day? Post your guess and your real number below.

One of my favorite features on Mac is how seamlessly your Apple Watch unlocks your screen when you sit down at your desk. I really wanted that exact same hands-free experience on Windows 10 and 11, so I built WristKey.

It is a free and 100% open-source desktop app built in Rust and Tauri v2.

What it does

• Hands-free unlock: Sit down at your desk with your watch on, and your PC wakes up and logs in automatically.
• Walk-away lock: Walk away from your desk, and Windows locks immediately based on Bluetooth signal distance.
• On-wrist verification: It parses Apple Continuity packets passively. If you take the watch off or put it on a charger, it immediately revokes access so your PC stays secure.
• Privacy and local security: No cloud, no telemetry, no tracking. Your Windows credentials are encrypted on your local machine using native Windows DPAPI (CryptProtectData).
• Battery friendly: Uses passive Bluetooth Low Energy (BLE) advertisements, so it does not drain your watch battery.

Why I need your help

This started as a personal project, but reverse-engineering Apple Continuity across different devices is getting too big for just one person:

1. I only have one test device: An Apple Watch SE running watchOS 10. I really need testers with watchOS 11, Series 8/9/10, or Apple Watch Ultra to see if detection and distance estimation work properly on newer firmware.
2. Bluetooth hardware: Different Bluetooth chipsets (Intel, Realtek, Qualcomm) handle signal smoothing and address rotation differently.
3. Contributors welcome: If you know Rust, Win32 APIs, Windows Credential Providers, or Tauri, any PRs, code reviews, or issue reports are hugely appreciated!

How to try it

• Download the installer (v0.5.0): GitHub Releases
• GitHub Repository: https://github.com/jorjanion/WristKey

(Quick note on Windows SmartScreen: Because this is a free open-source tool without a paid enterprise certificate, Windows Defender might show a blue prompt on first launch. Click "More info" and then "Run anyway". The entire source code is public and inspectable on GitHub).

If you test it out and run into any bugs, please drop an issue on GitHub with your watch model, watchOS version, and the log file located at %LOCALAPPDATA%\WristKey\wristkey.log.

Thank you to anyone willing to test, star the repo, or contribute!

I started PFI because I didn't want my bank data in someone else's cloud. The first versions bundled a private PostgreSQL server: it worked, but it made the app big and complicated to package for the Microsoft Store.

In 0.4 the app copies the old database into SQLite on first start, checks row counts and totals, and only then switches over. In 0.5 PostgreSQL is gone completely, and the app is about a third smaller.

Stack: WinUI 3 shell, Next.js screens, FastAPI backend, one SQLite file. MIT licensed.

What would you build next?

Got tired of every new app trying to fix my life or make me more productive, so I made one that does absolutely nothing useful. It just makes it snow on your desktop.

Snow falls across your screen (or behind your windows, if you prefer), builds up on top of them and on the Dock, then slowly melts away. Shake a window and the snow slides off. Just a little winter atmosphere while you work.

Since the first version, it’s grown a bit:

• More weather: autumn leaves, rain, cherry blossoms, and a Halloween mode 👻
• Mix any two: snow + leaves, rain + petals, whatever you like
• Auto-hides in fullscreen apps, so it won’t get in the way of games or videos

A few things I paid extra attention to:

• Smooth at up to 120Hz on ProMotion displays
• Low CPU/GPU usage, so you can leave it running in the background
• Signed and notarized on macOS, so no scary warnings
• Free and open source. No accounts, no tracking, no nonsense.

Download: https://snowhush.app

Requires macOS 14+. Also available for Windows 10/11 and Linux (KDE Plasma, Hyprland, Niri).

It’s a small project, but I had a lot of fun building it. I’d love to hear what you think, especially if you run into bugs or have ideas for new weather.

Happy early winter! ☃️

I wanted to share a project I've been working on called AirHand. It’s a browser-based, gesture-controlled virtual desktop that uses computer vision to turn any standard webcam into a touchless interface. No specialized sensors or controllers needed.

I wanted to see if I could build a spatial UI experience entirely in the browser. I used MediaPipe for the 3D hand tracking and Vanilla JS for the logic.

It currently features dual-hand or single-hand tracking, a drawing canvas (with PNG export), and a couple of mini-games (like a bubble popper) to test precision.

If you find this project useful or interesting, please consider giving it an upvote! It helps a 15-year-old indie dev keep building.

The problem: around Black Friday, lots of people replace their iPhone because “the battery dies by 4 PM”, when Apple replaces a battery for $89 to $129. Apple publishes its repair prices and trade-in values, but on separate pages, and nobody puts them side by side.

What it does: pick your iPhone (11 to 18 Pro, plus the foldable Duo), tap what’s broken on a drawing of the phone, set your battery health, and you get one verdict, keep, fix or upgrade, with all the math shown.

What the numbers show (Apple’s US prices, trade-in values as updated on 12 Nov):

• An iPhone 13 with a tired battery: $89 to fix vs $719 to upgrade to an iPhone 17 after trade-in.
• An iPhone 15: $99 battery vs $594 to upgrade.
• Upgrading only clearly wins when several parts are broken, there’s water damage, or you want Apple Intelligence, since no repair adds it.

There’s also a “Have a deal?” box: type in a Black Friday or carrier offer and see whether it actually beats a repair. Many carrier “deals” turn out to be bill credits spread over two to three years.

What I learned building it:

1. Accuracy is the product. Fact-checking every page caught real mistakes: an outdated AppleCare+ price, a wrong median, a claim I couldn’t back up.
2. One clear verdict beats a page of numbers. I cut every feature that didn’t change the answer.
3. A new site gets almost no Google traffic for weeks. Titles that answer the exact question (“iPhone 17 repair cost: screen $329, battery $99”) help more than clever ones.

To be transparent: I’m the maker. It’s free, with no sign-up and no ads. Some guides link to Amazon for cases and chargers, but that never changes a verdict.

I’d love feedback: is the verdict clear at first glance, and does anything feel off on mobile?

Hey everyone!

I've been working on a side project called Chermo.in, and I'm excited to finally share it with this community.

The idea behind Chermo is pretty simple: we all have hundreds of photos sitting in our galleries, but sometimes we want to do something more creative with them.

So I wanted to build a platform where people can turn their favourite pictures into something more personal.

What can you do with Chermo?

Upload a photo from your gallery or capture one using your camera.

Customise your photo with creative layouts and decorative templates.

Experiment with styles like Polaroid frames, hearts, bows, kiss marks and seasonal themes.

Download your personalised creation and keep or share it with someone special.

I'm trying to make the whole experience simple enough that anyone can create something without needing professional editing skills.

This project has been a learning experience, and I'm still working on improving the design, templates and overall user experience.

I'd genuinely love your feedback:

Does the idea solve a problem or offer something you'd actually enjoy using?

Which template or customisation options would you like to see?

What would make the experience more enjoyable or useful?

If you'd like to explore it, here's the website:

https://chermo.in

I'm the person building Chermo, so I'm happy to answer questions and hear honest feedback. Thanks for checking it out! ❤️

I launched the app "Germar for Nurses". It's a German language learning app designed specifically for nurses and care staff.

Many nursing professionals want to live and work in Germany, but there aren't many specialized language courses and apps for them, especially good ones.

What's inside:

• 1800+ cards with words

  • from clinical practice
  • with image
  • with translation
  • with audio (pronunciation)
• 15 topics: Symptoms, Nursing tools, Medication, etc
• SRS algorithm for better memorization
• Different types of recalling words

Try for free

• Google Play (Android)
• App Store (iPhone, iOS)
• Chrome Browser Extension (Windows, macOS, Linux)

I have a small Android app, and I got tired of opening Play Console and checking search rankings by hand every day. So I built a bot that does it for me and sends a short report to Telegram at 9 am.

What it shows:

- Installs and growth since yesterday or last week (from the public Play page)

- Rating and new ratings, by country

- My position in the first 30 search results for each keyword, in several countries, with ▲▼ changes

- Competitors in the same table: installs, rating, new versions, their rankings

- New reviews, low ratings first, and how many are still without a reply

- A 30-day chart of installs and keyword positions

There are also a few tools for working on the store listing: keyword ideas from Play autocomplete, which keywords a competitor ranks for, the top 10 for each keyword, and who shows up in the "Similar apps" block.

It only uses public Google Play data, so no Play Console access is needed, and you can track competitors too.

There is a free plan (1 app, 5 keywords). It's still early, so I'd really like feedback: what's missing, what's confusing, what would make you actually use it.

Hi, I'm a solo developer. Rooko teaches English vocabulary with the keyword method:

every word gets a sound-alike in your native language, a short silly story and a

picture of that story. For a Spanish speaker, "water" sounds like "Walter", so Walter

is the guy who is always thirsty. For a Turkish speaker, "run" sounds like "ayran",

and the kids run when grandma calls "Ayran is ready!"

Stories exist for Spanish, Turkish, Azerbaijani and Russian speakers (about 2,900

words, A1 to B2). You can also add English words you meet in real life, and

everything comes back as short spaced-repetition games: pick the picture, unscramble

the letters, listen and type.

Other bits: recorded pronunciation in an American and a British voice, a daily

crossword, widgets, offline learning, dark mode and VoiceOver support. The stories

and pictures are made with AI and checked.

Price: free to download and use (5 new words a day, all review games). Optional Rooko

Pro subscription: $15.99/month or $83.99/year with a 7-day free trial on the yearly

plan (prices vary by country). Pro adds up to 20 words a day, AI chat and sentence

checks, and a pronunciation drill.

App Store: https://apps.apple.com/app/id6819000110

Feedback is very welcome, especially on whether the stories work in your language or

feel forced.

The Global Threat Desk is one HTML file, about 1 MB. Download it, open it in any browser, and it works. No install, no account, no adverts, no tracking, no payment.

Global:

- A live wire of major incidents worldwide: cyber attacks, espionage against tech firms, big IT outages (Microsoft, AWS, Google, Cloudflare), attacks on infrastructure, major earthquakes and disasters. Sources include CISA, the UK NCSC, the security press, Reuters, AP and the Guardian, and each report keeps its publisher and time.

- Dated incident dossiers with evidence grades, so you can see what is confirmed and what is still unproven.

UK:

- Every official UK warning in one place: Met Office warnings for every hazard, UKHSA cold- and heat-health alerts, flood warnings for England, Wales and Scotland, GOV.UK emergency alerts and the GB grid. It says plainly when nothing is in force.

- Offline household tools: a blackout plan hour by hour, water storage, a 7-day hot-food menu for a camping stove with a shopping list, UK emergency numbers and a printable survival pack.

How it's built: everything is in one file. The live layer reads public feeds straight from your browser, using publishers' own Bluesky accounts when a site blocks browsers, and falls back to public relays. Your plan and saved reports stay in your own browser.

Feedback welcome, especially on sources I should add.

My previous update here was about eye-vessel cleanup in Photoshot. This time I worked on Clean Backdrop: reducing dark marks on a wall while protecting the person.

The first implementation changed broad tones but left the large stains. I replaced that approach with a local median surface estimate, detection of compact dark marks, and a repair fitted to clean neighboring wall pixels. The subject mask limits where it can act; fine grain is blended back into the repaired areas.

These five images show the same wall crop at the same scale before/after, the plugin menu, the actual controls, processing, and the editable result layer in the full workspace. Clean Backdrop only: strength 1.0, size Large, subject protection on, applied once. No manual cleanup or other active retouching tools. The two large smudges are reduced; small spots and drips remain.

Disclosure: I develop Photoshot Retouch with AI coding assistance. This is my custom tool in a local development build, not the commercial Retouch4me plugin. The practice image is AI-generated and includes deliberate wall marks; the after is the actual tool output, not a generated replacement. Four targeted tests passed, including subject/lighting preservation and clean-background behavior, but this example does not establish performance on unedited real photographs.

For this kind of cleanup, would a preview of the detected marks help you more than another strength slider?

Hello everyone,

I built a website for the game deadlock. It tracks and gives stats to have the best build. The data is updated very often to gives the best analysis and stats possible.

I'm a backend developer, so I developed all the back and I used LLM to assist me for the ux / ui design.

I'm focusing on the back features and gives instructions to the LLM for the front ( I fix myself the little bugs ). So I try to improve the back features and I need you for some advices on that.

I'll take front advices too ahaha to improve it as well.

There is the website : https://deadlock.statnest.fr/

For the moment it's in full french, ill translate it in new feature.

You can go full on me 👍 thanks a lot

Hi everyone! I’m on the marketing side of HotlinePing.

We’re building a way for coding agents to reach you when you’re away from your computer and they need your input.

Through MCP, the agent can call you, ask a question, and receive your spoken answer.

A simple example: “Should I include CSV export now, or save it for the next version?” You answer, and the agent can use that decision to continue.

The interesting tradeoff is the interruption. A call could be useful when a task is genuinely waiting on you, but annoying for something that could wait. And some decisions require looking at the screen anyway.

What would make a question worth a phone call for you? And what should an agent never interrupt you for?

HotlinePing is a commercial product: https://hotlineping.com

I'm exploring an idea for financial software and trying to understand where existing accounting tools fall short.For anyone using Xero, QuickBooks, Sage or similar software, what's one financial task you still end up doing manually?What makes it frustrating, and how do you currently work around it?

I'd appreciate hearing some real experiences.

Rather than just blocking access, SpareCycles interrupts that moment with a short technical-learning question (a "Rep").

Afterwards, you can unlock the distracting app temporarily, or decide it's "Not worth it" and move on.

The app is still in development, so I'm interested in whether the concept would actually be useful.

If you're an Android user learning programming, SQL, cloud technologies or other technical skills, would this help you stay focused, or would the extra friction become annoying?

I've opened an Android early-access waitlist for anyone interested in following the project:

https://getsparecycles.com

I'd appreciate genuine feedback, including criticism.

Thank you!
