Frequently asked questions
What does RepChime do?
RepChime is an iPhone fitness utility with two main modes: a configurable HIIT timer for interval sessions and a goal-based counter that can track supported repetitions using device sensors or the front camera.
Which exercises can RepChime count?
The current App Store listing names push-ups, sit-ups, pull-ups, and squats. Available detection modes vary by exercise; front-camera counting is available for push-ups.
Can RepChime count repetitions automatically?
Yes. Counter mode offers motion, rotation, automatic, and front-camera detection options. Accuracy depends on the exercise, device placement, movement range, lighting, and selected sensitivity.
Can I save my own workouts?
Yes. You can save Timer and Counter presets and quickly return to favorite configurations. RepChime Pro adds more preset capacity and the full editing workflow.
Does RepChime keep running in the background?
No. iOS may pause RepChime when it is not active. With Pro, RepChime recalculates the timed phase from elapsed time when you return, and scheduled iOS notifications can alert you to phase changes.
Does RepChime require an account?
No account is required. Workout presets and settings are designed to stay on your device. Apple handles App Store purchases and entitlement status.
Train responsibly. RepChime is a fitness utility, not a medical device, coach, or substitute for professional advice. Use proper form and stop exercising if you feel pain, dizziness, or discomfort.
