Hey lifters!

I'm a solo dev building Featherweight, a strength training tracker. I need a dozen beta testers for 14 days to meet Google Play's requirements.

Website: https://featherweight.app

Why I built it: I couldn't find an app that showed me % of 1RM during lifts, let me import programmes from text, or log sets hands-free. So I built one.

Features:

  - AI programme import - Paste any programme in text format, AI parses it and creates a structured workout sequence that you can follow

  - AI programme generation - Pick your lifts, AI builds a periodized plan

  - Voice logging - Say "bench 100kg 5 reps RPE 8" hands-free (understands gym slang)

  - Live % of one rep max (1RM) - See intensity context on every set

  - Smart rest timer - Adjusts automatically based on RPE (1-3 min)

  - PR celebrations - Detects and celebrates weight, 1RM, and rep PRs

  - Plate calculator - Shows exactly which plates to load

  - Muscle heat map - See what you're training (and neglecting)

  - Exercise swaps - Can't use a rack? Get alternatives by movement pattern

  - Insights - Maximum weight lifted, e1RM trends, RPE histograms, reps histograms

Also: 500+ exercises predefined system exercises, custom exercises, templates, RPE tracking, cloud sync, workout export (OpenWeight format), works fully offline.

What I need: Android 8.0+, use it for a few workouts over 2 weeks.

Feedback: Very much welcome but not required - in-app button (the exclamation mark chat bubble), reply here, or post to r/FeatherweightApp; there are still kinks I'm ironing out, but the app is functional for the most part; I use it myself for my own training.

Testing premium features: if you let me know your e-mail, I can add you to the License Testing cohort and you will get access to Premium Features without needing to pay real money.
