A nutrition companion for endurance athletes
Hey HN! 6 Months ago I soft launched https://mavr.app/, an IOS companion app for any endurance athletes nutrition. Over the 6 month period we valid some of our key features: 1) Gut training during training your training block, making sure you can handle the carbs during your race 2) Performance focused meal planning. Making sure you can get everything our of your key sessions and recovery optimal 3) Race aware fueling plans. Making sure your fueling plan is efficient and planned specifically for your race course with our 1k+ race course library. We've been aiming for a slow…
What it does
In the maker’s words, at launch
Hey HN! 6 Months ago I soft launched https://mavr.app/, an IOS companion app for any endurance athletes nutrition. Over the 6 month period we valid some of our key features: 1) Gut training during training your training block, making sure you can handle the carbs during your race 2) Performance focused meal planning. Making sure you can get everything our of your key sessions and recovery optimal 3) Race aware fueling plans. Making sure your fueling plan is efficient and planned specifically for your race course with our 1k+ race course library. We've been aiming for a slow takeoff, so we still had room to tweak the app together with some top athletes in their sport. In the meantime 30+ athletes completed a race with Mavr. All reporting a 20-30% performance gain during their training block and around an 8-15% gain during their race. Happy to chat more about nutrition and endurance sports! Let me know if you have any questions, ideas or feature requests!

Im a triathlete and the data for my training lives in 6 apps: Garmin, Strava, WHOOP, Intervals.icu, Wahoo, Withings, Apple Health, sometimes Hevy. Every morning Id eyeball a few of them and make a call on whether to do the planned session. For the past month I have been building a thing that does this for me, and got it to the point where I use it myself every day. It OAuths into whatever platforms you connect, reconciles the activities (tbh harder than it sounds — same ride shows up in Strava, Garmin, and Wahoo with different timestamps and rounding), computes daily load and readiness, and…

i built a heart rate zone training app for runners. ios + apple watch. custom zones, real-time haptics, post-run graphs. all the “smart” stuff you’d expect. but i never talked to a single runner before building it. not even myself lol. started as a thesis → kept building → added features → added a paywall (€4/month!) → launched it → and yeah… no one cared. zero feedback. zero users. just code in the void. i recently made the whole thing free. not trying to “sell” anything now — just seeing if it’s actually useful, and listening this time. curious how others handle this. ever build…
- IBI Built a Lightweight Nutrition Tracker for the iPhone2024 · apps.apple.com · ▲8
Hey HN, I was overweight in college and started my weight loss journey using an app called MyFitnessPal. Tracking calories not only helped me lose weight but also taught me a lot about nutrition and helped establish healthy eating habits that continue to benefit me. However, I’ve always been frustrated by the existing nutrition tracking apps. Many are slow and bloated, lack accurate nutrition data, or don’t respect user privacy. I wanted to build something that I’d love using myself. A few things that make FitBee stand out: * Fast, lightweight and to the point - The app is just about…

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.
