GymTemper

GymTemper is a workout tracker built for lifters who want simplicity, precision, and complete privacy. No account. No cloud. No subscription. Your data stays on your device, always.

🏋️ LOG YOUR SETS

Two exercise types: strength (weight + reps) and timed (duration in seconds — for Plank, Wall Sit, L-Sit, and similar). Every set shows your last session's values right below the input fields. The target rep range is shown in the exercise subtitle so you always know what you are aiming for. Add multiline notes to any workout and they save instantly. Tap the checkmark when a set is done — a green indicator confirms it and the screen scrolls automatically to the next set.

⏱️ AUTOMATIC REST TIMER

A rest timer fires automatically the moment you complete a set. It keeps counting in the background as a persistent notification with a live countdown you can see from the lock screen. Pause, resume, add 15 seconds, or skip the rest at any time — without reopening the app.

📋 ROUTINE TEMPLATES

Save any finished workout as a routine template and start your next session from it with a single tap. Add, remove, or reorder exercises and adjust target sets. Your routines live entirely on your device — no account or sync needed. Routines support multi-day programs, for example a PPL split.

📅 WEEKLY TRAINING PLANS

Assign any routine to any day of the week. The home screen shows today's planned workout with a one-tap Start or Resume button. Missed a session? The app carries it forward and marks skipped days on the calendar so you can track your consistency. Set an optional start and end date to schedule a training block.

🗓️ WORKOUT HISTORY

Every session is saved with its duration, total volume, and a full set breakdown per exercise. Open any past workout to review your numbers, save it as a new routine, or share a plain-text summary to any messaging or notes app.

📈 EXERCISE PROGRESSION

Tap any exercise in a past workout to open its progression screen. Strength exercises show a line chart of estimated 1RM over time using the Epley formula with RIR weighting for higher accuracy, plus stat cards for your top weight and current e1RM. Timed exercises show a chart of your best session duration over time. A list of your most recent sessions is always shown at the bottom. Know exactly whether you are getting stronger.

🚀 GET STARTED IN SECONDS

New to GymTemper? The Starter Pack walks you through building your first routines in under a minute. Pick your training focus (Full Body, Upper Body, or Legs & Glutes) and how many days per week you want to train. The app generates ready-to-use routine templates from a curated exercise library — you can customize the exercises before saving.

🗂️ EXERCISE LIBRARY

Browse a built-in library of strength and timed exercises. Filter by category (Barbell, Dumbbell, Machine, Cable, Bodyweight, Other) or by muscle group (Chest, Back, Shoulders, Arms, Core, Legs, Glutes, and more). Can't find what you need? Create your own custom exercises.

⚙️ BUILT FOR YOUR WORKFLOW

Switch between kg and lb at any time without losing data. Set your default rest duration anywhere from 30 seconds to 5 minutes. Choose light, dark, or system theme. Switch the app language between English and Spanish.

🔒 YOUR DATA STAYS WITH YOU

GymTemper works 100% offline. There is no user account, no cloud sync, no ads, and no social feed. The only data sent automatically are anonymous crash reports to help fix bugs — nothing personal, nothing identifiable. Your entire workout history never leaves your phone.

Works on Android 8.0 and above, on phones and tablets.
