PUMPD AI Coach
Your personal trainer, in your pocket
What it does
PUMPD is a personal strength-training app that plans your workouts, guides every session, and adapts what comes next. It builds a complete multi-week program around your goals, experience, schedule, equipment, and preferred workout length. Informed by current exercise science, PUMPD uses the reps and effort you log to adjust weights, reps, sets, recovery, and deloads. Its AI Coach knows your training history, explains changes, answers questions, and helps adjust your plan.
PUMPD gives you exact weights and reps for every workout, then adjusts as you get stronger.
PUMPD builds your training block, prepares every workout, and adapts the work as you get stronger. Your goal, schedule, and equipment shape the block. Every workout arrives ready. The reps and effort you log set the next target. Goal, schedule, session length, and equipment become a complete multi-week block. Your exercises, sets, weights, and reps are already planned. Follow the target, then record the reps and effort you actually did. PUMPD adjusts as you improve and gives you a plain-language reason for every change. Real records and strength trends, built from the sets you actually logged. No inflated wins. Ask why a target moved, stayed, or dropped and get a plain answer from your own…from getpumpd.com

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.
