Gym Book

Gym Book is a simple, fully offline member manager for small gyms and fitness studios. No account, no sign-up, and no internet connection required — open the app and start adding your members.

Keep every member organized with their plan, fee, and expiry. The Members list shows at a glance who is Active, Expiring soon, or Expired with a clear color-coded status. Recording a payment takes seconds and automatically extends the member's plan by the plan length, so renewals just work. The Attendance tab lets you mark daily check-ins with a single tap and shows today's count up top — pick any past date to review who attended. The Reports tab turns it all into the numbers that matter: active vs expired members, revenue collected this month, a six-month revenue chart, a seven-day check-in trend, and a breakdown of members by plan.

Everything is stored privately on your device. Gym Book collects no data, shows no ads, and requires no permissions.
