x100 — the app that counts. x100 helps you keep track of your reps during workouts. No need to count reps in your head anymore, let us do it for you. Relax, enjoy your workout music, watch the news or listen to an audiobook while x100 does the counting. We are not here to motivate you, inspire you or improve your form. We just help you by taking care of one simple task, making your workout easier and more fun.
