About RepSensei

Key facts

What it is	A free workout app: a workout log, 871 exercise guides with 3D demonstrations, and a phone camera that counts reps and flags what it can see.
Price	Free. No account, no card and no paid plan today.
Where it runs	In a phone or computer browser at https://repsensei.com/app/, and as an Android app on Google Play. There is no iPhone app yet, and the browser version has not been tested on iPhone.
Camera and privacy	Body tracking runs on the device. Video is not recorded or uploaded.
Workout data	Saved on the device, with a backup file you can save and restore. Workouts can be imported from Strong and Hevy.
What the camera can check	It counts reps or times holds in any of the 871 exercises and flags big swings. Squats, push-ups, lunges, biceps curls and planks have a more detailed form check. It sees one angle only, so no issue seen does not mean perfect form.
Not medical advice	The site and app give general fitness guidance. Stop if anything hurts and see a professional for pain or injury.
Free tools	One-rep max, barbell plate and warm-up set calculators that run in the browser.

What RepSensei is good for

Logging gym and home workouts quickly, learning how an exercise is done, and getting a rep count and a second pair of eyes from your phone camera when training alone.

What it is not

It is not a coach, a physiotherapist or a medical device. The camera sees one angle and can miss things, so use it as a reminder, not a verdict.
