Stack - Gym Tracker

Lifting log, distraction-free

Free · Designed for iPad. Not verified for macOS.

A focused, local-first lifting log. Plate math for bars and machines, muscle coverage, big-three trends, Live Activity, and custom themes. No accounts required. Stack - Gym Tracker Stack is a focused, local-first lifting log for people who actually lift. No bloated feeds, no streak-shaming, no nag screens. Just a fast, beautiful way to plan your sessions, log every set, and see real progress over time. WHY STACK • Built for the rack, not the couch. Big-tap targets, a custom numeric keypad, and quick-swipe weight/rep adjustments mean you can log a set in seconds without breaking flow between rests. • Local-first by default. Your data lives on your device. Optional iCloud sync via CloudKit keeps it across iPhones. No third-party servers, no analytics farms. • Quiet by design. No ads, no upsell modals, no notifications you didn't ask for. LOG SMARTER • Splits and routines: build your own (Push / Pull / Lower, full-body, classic 4-day, whatever you want) or start from sensible defaults. • Exercise library: 100+ curated movements with primary/secondary muscle mapping, plus your own custom exercises. • Per-set richness: weight, reps, warmup tags, time, cardio (distance, incline, zone), bodyweight, machine pin position, lb or kg. • Live Activity: an in-progress workout pins to your Lock Screen and Dynamic Island so you can see the set you're on without unlocking. PLATE MATH WITHOUT THE MATH The plate calculator handles real-world racks: Olympic, Women's, EZ, and now No Bar for plate-loaded machines. Type a target and Stack solves the per-side distribution against your available plates, or tap plates manually for a specific layout. The new Initial Resistance field captures the built-in load on Hammer Strength and similar machines so your typed weight still maps to a clean plate count. SEE THE WORK • Muscle coverage per session: which regions you actually trained, and which you didn't. • Big-three trends: bench, squat, deadlift trajectories with one-rep-max estimates. • Per-exercise charts, weekly volume, and progressive-overload prescriptions for your next session. PERSONAL TASTE A built-in design system gives you full theme control: light, dark, or system; five accent palettes (Forest, Navy, Maroon, Walnut, Stone) plus customizable colors. Pick the look that disappears for you mid-set. PRIVACY AND OWNERSHIP • Your data is yours. Export the whole history to JSON anytime, import it back on a new device. • Apple Sign-In and iCloud are optional, never required. • No ad SDKs, no tracking. Questions or feature ideas?

History got a full calendar. Tap any day to see what you did in place, no popup. Personal records from normal sessions now show up on the day you set them. Days with a 1RM test get a star on the calendar, and the result card shows whether you hit your goal. The home screen is tighter: Today and This Week in one section, color-coded frequency bars, and a cleaner pre-workout screen on the Train tab.
