Exponential: Strength Tracker

Get a little stronger every session. exponential is a calm, fast training journal for lifters. Pick your program (Push / Pull / Legs or Upper / Lower), start an exercise, and log what you actually lifted. Every rep adds up, and you can watch it compound. LOG IN SECONDS • Swipe a set to mark it done; swipe again to undo. • Press Log once to save. Hold and slide to rate the session Easy or Hard. • An instant confirmation with Undo, right above the tab bar. • Tap any set that isn’t done yet to fine-tune weight and reps on a wheel. • See your last session and your best set right above today’s target. • Optionally start each new session 2.5 kg (about 5.5 lb) heavier than the last. REST WITHOUT THINKING • Built-in rest timer: tap to start or pause, swipe up or down to adjust, long-press to reset. • Set a default rest, and a different rest for any exercise. • Start it automatically when you complete a set, if you like. • A notification when rest is over, and a live countdown on your Lock Screen and in the Dynamic Island. SEE YOUR PROGRESS • Personal records and an estimated one-rep max for every exercise, with a progress chart. • Weekly volume chart for your total and each split, compared with the week before. • Your rhythm: the last 14 days at a glance, color-coded by split. • A monthly calendar of every session, and a full history for each exercise. • Home Screen and Lock Screen widgets for your week, your rhythm and what’s next. MADE FOR YOUR ROUTINE • Push / Pull / Legs or Upper / Lower, each split with its own exercises. Add, remove and reorder them. • Kilograms or pounds, 1–12 default sets, Monday or Sunday week start. • Haptics and reduced motion you control. • Optionally save each session to Apple Health as a strength training workout. PRIVATE BY DESIGN • No account needed. Create a local profile with your name and an optional photo, or continue as a guest. • Your journal stays on your iPhone, or in your private iCloud if you turn on sync. Nothing is collected, tracked or sent to us. • Export a JSON backup whenever you want, and import it to restore. • Delete your profile or reset the app at any time, and it’s gone. Small steps. Exponential progress.
