Stronk

Stronk is a free, open-source weightlifting tracker built as an installable web app. It keeps the focus on the essentials of lifting: logging workouts as you train, recording sets, reps and weights for each exercise, and reviewing how your performance changes over weeks and months. Because it is a progressive web app, you can install it straight from the browser onto your phone or desktop, and it behaves like a native app once on your home screen.

Privacy is built into how Stronk works. There are no accounts to create, no subscriptions to pay, and no third-party tracking — every workout you log is stored locally on your own device. The project is committed to staying free, and cloud backup for cross-device sync is under development for users who want an extra layer of safety for their training history.

Stronk is a good fit for lifters and home-gym users who find commercial training apps bloated or paywalled. If you want a straightforward, private way to track your lifting — without the ads, upsells, or data harvesting of apps like Hevy, Strong, or MyFitnessPal — Stronk is worth a look. The source code is available on GitHub under the GPL-2.0 license, and the project welcomes feature requests and pull requests.
