Everything your gym needs.
We built every feature gym owners have asked us for. Nothing is bolted on, nothing is a plugin.
WhatsApp automation
Reminders, renewals, birthdays — fully automated on the platform members already use.
Staff & trainers
Assign trainers, track shifts, split commissions automatically.
Reports & analytics
Revenue, retention, class utilization — exportable, always up to date.
POS & inventory
Sell supplements, apparel, and add-ons at the front desk. Stock auto-updates.
Multi-branch
One rollup dashboard across all branches, separate controls per location.
Role-based access
Owners, managers, trainers, and front-desk — each sees only what they should.
Know your numbers.
Revenue, retention, class fill-rate, trainer performance — live, on one screen. Built for owners who actually run the spreadsheet.
Gym owners don't go back.
We built Kasratbook with gym owners, not for them. Here's what they say.
"Collections went from a weekly headache to fully automated. We recovered ₹2.1L in missed renewals in the first month."
"The member app is the best thing that happened to our retention. Attendance is up 40% since we shipped workouts through it."
"We run four branches. Kasratbook gives each branch manager the data they need without us losing central control."
Simple pricing. Fair for every gym size.
