Trunk: Gym & Workout Tracker

Free forever, no subscription. Your workout history stays yours. And if you plan your lifts with ChatGPT, Gemini, or Claude, Trunk connects to your real growth.

Trunk is a FREE workout tracker built for people who actually go to the gym. No subscriptions, and it stays that way forever.

Most fitness apps lure you in with a free trial and then lock your own data behind a monthly fee. Trunk was built to be different. Your workout history, your progress graphs, your analytics — all of it is yours from day one, with nothing held back.

CONNECT YOUR OWN AI Already use ChatGPT or Claude to plan your training? Trunk connects straight to it. Your real logged numbers go out, a program comes back, and you import it in two taps — so your next block is built on what you actually lifted instead of a guess. It's a one-time unlock, and like everything else in Trunk, there's no subscription. Ask ANY Ai:

"What is my program lacking?" "What lift of mine has the highest likely hood of injury?" "What percentile am I for Squats compared to the rest of the world?" "Make a detailed visual chart displaying how I've improved over the past 3 months."

TRACK YOUR LIFTS Log your sets, reps, and weight with a fast, intuitive interface designed for use between sets. Tap, log, done. No clutter, no unnecessary screens. Trunk gets out of the way and lets you focus on your workout.

SEE YOUR PROGRESS Every exercise builds a visual history over time. Watch your volume, strength, and consistency grow through interactive graphs and a unique "trunk" progress visualization. Trunk compares your most recent session to your previous one automatically, so you always know if you are improving.

STAY ON TRACK A built-in rest timer keeps your pacing tight. Get notified when your rest period is up with push notifications, haptic feedback, or even a flashlight alert. A Live Activity widget sits on your lock screen during workouts so you never have to unlock your phone to check your timer.

ORGANIZE YOUR WAY Create unlimited profiles, sessions, and exercises. Structure your training however you want — push/pull/legs, upper/lower, full body, or your own custom split. Rename, reorder, and manage everything with simple swipe controls.

WORKS OFFLINE Trunk syncs your data to the cloud when you are connected, but works perfectly without internet. Your workouts are cached locally so you never lose a set, even in a basement gym with no signal.

YOUR DATA IS YOURS Sign in with Apple or Google. Your workout data is stored securely. Delete your account and all associated data at any time from Settings — no emails, no hoops, no waiting period.

BUILT BY A LIFTER Trunk is not backed by a venture capital fund trying to monetize your habits (ew). It is an independent app built by someone who got tired of paying monthly fees just to log a **** bench press. Every design decision is made from the perspective of someone who actually uses this app in the gym, every day.
