Stark Gym: Workout Tracker

Stark is your gym logbook: plan your routines, log every set in a second and see your lifts climb week after week. Everything is free, with no limits and no subscription. The app's interface is in Spanish.

ONE SET, ONE GESTURE
Open your workout and the set you're on fills the screen: the weight, the reps and the bar drawn with its plates. Drag to adjust the weight, set the reps and swipe up to log it. The next set opens on the numbers you just lifted.

EVERY PR, THE MOMENT YOU HIT IT
When a set beats your best estimated 1RM, Stark stamps it as a personal record on the spot. When you finish, each session becomes a poster with your volume, your sets and your records, ready to share with a QR code that leads to Stark.

YOUR REST, ALWAYS IN VIEW
Logging a set starts your rest. Follow it in the Dynamic Island and on the Lock Screen, add 15 seconds or log the next set without opening the app. Stark remembers how long you rest on each exercise.

ROUTINES AND PROGRAMS
Build routines by training day, start from any program in the library, or let the onboarding questions build one for you. Share routines as .stark files.

BRING YOUR HISTORY
Import your workouts from the CSV file other workout apps export. Before importing you see how many workouts and sets come in and which Stark exercise each one maps to.

MORE THAN 1,000 EXERCISES
Videos and instructions, favorites and muscle-group filters. Add your own exercises, with a photo, to match your equipment.

WIDGETS AND CONTROL CENTER
The "Tu semana" widget shows this week's workouts against your goal and your streak; "Tu entrenamiento" shows your next training day with a button to start it. On iOS 18 or later, a Control Center control logs your next set.

YOUR DATA STAYS ON YOUR IPHONE
No account, no ads and no tracking. Your workouts are stored on your device.

ALL OF STARK, FREE
Everything is free: unlimited logging, your full history, records and posters, your routines and every program in the library. Also:
• Suggested weights: Stark suggests the weight for every set from your history and progression profile, and tells you why.
• Progress and stats: a chart for every exercise and, in the Cuerpo tab, the muscle map and your recovery.
• Coach: a note after every workout and an export of your data to analyze it with AI. On supported iPhones running iOS 26 with Apple Intelligence turned on, the coach runs on the device.
