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.

Ratings & Reviews
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.
