LeuBox: the offline-first training log for powerlifters
LeuBox builds a four-week strength block from your Training Max values for
bench press, squat and deadlift, then records every session - sets, reps,
weight, RPE, fatigue, pain and notes - with no internet connection needed.
Working weights calculated from a Training Max factor you control.
Sessions stored on the device, so a workout survives an app restart.
Progress view with completed sessions, total volume and average RPE.
Optional account for cloud sync, leaderboards and Trainer chat.
Available for Android, iOS and the browser, in English, Spanish, French,
German and Romanian.
