iPhone · Workout logger + coaching intelligence

The training system that trains you back.

Log a set in three taps. Run programs that actually progress. Every session feeds an engine that tells you what to do next — and when to back off.

Free to try · Pro unlocks the full program library and coaching intelligence.
What it does

Built for the set you're about to do

No spreadsheets, no scrolling through menus mid-set. The logger is designed to disappear so you can train.

01

Three-tap logging

Weight → reps → RPE on a purpose-built keypad. Your last numbers ghost in so you only type what changed.

02

Coaching intelligence

A Training Score and per-lift progression targets computed from your own history. It tells you when to add load and when to hold.

03

Real programs

Twenty-plus periodized programs across bodybuilding, tactical, legends and FORGED — weeks, sessions and progressions already written.

04

Advanced protocols

Clusters, myo-reps, rest-pause, supersets, circuits, AMRAP and EMOM — with timers that run the round for you.

05

PRs and history

Estimated 1RM tracking, PR alerts mid-session, strength trends per lift, and a calendar of everything you've done.

06

Apple Health

Resting heart rate and sleep feed readiness flags, so the plan bends on the days your body says so.

Program library

Pick a plan. Press start.

Every program lands on your calendar with its sessions built — you open the app and the day's workout is waiting. Tap a collection, then a program, to see week one.
