Stronk
Open-source weightlifting tracker — log workouts, sets, and reps with data stored locally. Free, privacy-respecting alternative to Hevy and Strong.
Open source alternative to:
Stronk is a free, open-source weightlifting tracker built as an installable web app. It provides a focused interface for logging workouts, recording sets and repetitions, and reviewing how performance changes over time. All data is stored locally on the user's device, with no accounts, subscriptions, or third-party tracking.
The project is intentionally minimal — built around the core task of logging lifts and reviewing historical progress without the subscription fees, upsells, or feature bloat of commercial fitness apps. Cloud backup support is in development for users who want cross-device sync.
Stronk is a strong fit for lifters and home-gym users who want a simple, private alternative to apps like Hevy, Strong, or MyFitnessPal — without sharing their training data with a third party.
