Stimulus: Gym & Training

Stimulus is a beautifully simple workout tracker for lifters who care about progress, not clutter. Log every set the moment you finish it, then watch your strength climb week over week.

Built for the gym floor — fast to log, easy to read, and quietly powerful.

WHAT YOU CAN DO
• Log workouts in seconds — weight, reps, and full drop sets
• Track bodyweight exercises and added-load sets
• Build your own exercise library with custom tags and muscle groups
• See estimated 1RM, total volume, and rep counts on every exercise
• Review your full workout history on a clean calendar
• Chart your progress over time and spot your PRs
• Track and graph your body weight, with backdated entries
• Switch freely between kilograms and pounds

DESIGNED TO GET OUT OF YOUR WAY
No ads. No clutter. No endless setup. Just open the app, start a workout, and log. Stimulus uses password-less sign-in — we email you a one-time code, so there's no password to remember.

YOUR DATA, YOURS
Your workouts sync securely to your account so they're safe and available. You can edit recent workouts, and delete your account and all your data at any time, right from the app.

Whether you're running a structured program or just chasing your next personal best, Stimulus helps you train with intention and watch yourself get stronger.

Track every set, rep, and drop. Watch yourself get stronger.
