  1. 1.in brief

    a gym log for iPhone that never talks to a server

  2. 2.in general

    Sets, estimated best lifts and total volume, with nobody to sync them to.

  3. 3.in particular

    An offline workout logger built on the phone’s own database. No account, no subscription, no waiting.


note

Logs weight × reps per set with estimated 1RM inline, and charts 1RM and total volume per exercise over time, all on-device. WatermelonDB4’s native SQLite bindings (Objective-C/C++, compiled with Xcode and sideloaded, since they can’t run in Expo Go) give zero-latency offline queries, with an auto-seeded Push/Pull/Legs preset, a custom routine builder, and imperial/metric respected everywhere.

note

Records weight and repetitions for each set with your estimated best single lift shown inline, and charts strength and total volume per exercise over time, entirely on the phone. It uses the phone’s own database directly, which means queries return instantly and work with no signal, but also means it has to be built and installed the long way rather than through the usual quick preview tool. It arrives with a push, pull and legs plan already set up, a builder for your own, and both imperial and metric respected everywhere.
