ContextFolder
Context-aware home screen folder for Android
What it does
A while back there was an app called Contextual App Folder (C.A.F.) that did exactly this - a home screen folder whose contents changed based on context. It got pulled from the Play Store in 2023. ContextFolder is a modern take: each app icon carries its own rule - show, hide, or promote based on Bluetooth, day or time, or driving detection - plus a manual profile layer you can switch by hand. Free tier with limits; one-time purchase unlocks more, no subscription.

- WRWalkbase, room-level context for your apps.2011 · ▲11
Hi guys! Our team of HN lurkers been hard at work for what feels like an eternity now and today we're proud to present our first public product: The Walkbase library for Android. You can get it at www.walkbase.com With Walkbase, app developers can push location-specific room-level context (e.g. in-game content, coupons, mobile ads) to various smartphone apps. The idea is to give you a logical context (e.g Starbucks, SOMA) rather than an approximate GPS position for your users and we hope devs will be able to build a bunch of cool stuff on top of this. We hope you like it and find it useful.…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
