Every push-up becomes an attack in a camera-counted RPG game
A fitness RPG where your real pushups and squats, counted live by the camera, fell monsters and level up your hero. On-device pose detection, no tapping.
In plain words
Pushup RPG is a fitness game for iOS and Android that turns real exercises into monster-fighting action. Players prop up their phone and perform pushups and squats, which the device's camera counts in real time using on-device pose detection to deal damage to enemies. The game features 48 monsters across 8 biomes and offers live multiplayer duels, with progression tied solely to completing actual reps rather than tapping or idle timers.

Prop up your phone and drop down. Every real rep, counted live by the camera, strikes a blow against the dark. Pushup RPG is a free iOS and Android fitness game whose front camera counts your reps on-device. Pushups and squats are the ones that fight: 48 monsters, or a live duel against a friend. No tap-to-progress, no idle timers. The only way forward is real reps. On-device pose detection counts your pushups in real time. No manual tapping and no wearables: a rep has to be seen to count. Each rep deals damage. Fell 48 hand-crafted foes across 8 biomes, from timid slimes to Aurelion, the Astral Eye. Drops from Common to Mythic. Equip, upgrade, reforge and salvage gear.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

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.
