A front desk and member app built around the way B-Strong runs its studio

B-Strong is a fitness studio in Serbia. We built the desk app staff use to check members in, the phone app members carry as their membership card, and the server that keeps them in sync.

At the front desk

  • Check-in by codeThe member shows the code on their phone and the desk camera scans it. A large green panel shows the member’s name and today’s session and trainer, or a red panel shows why check-in failed.
  • Renewal remindersWhen a membership ends within three days, the desk tells staff to remind the member.
  • Manual check-inBy name or phone number, for when a member forgets their phone.
  • Today’s sessionsWith who has already arrived.
  • Bookings for membersStaff can book any member into any session, or cancel a session and give everyone their credit back.
  • Works through outagesCheck-in, member records and payments keep working without internet and sync once it’s back.
  • Windows and MacThe Windows app updates itself.

In the member app

  • The membership cardA QR code that changes every 30 seconds. The phone creates it, so it works without signal, and a code can’t be used twice.
  • Booking sessionsMembers book individual, semi-private and group sessions for the current week. Every session has a set number of places, and next week’s sessions open on Sunday morning.
  • Fair cancellationsCancel at least 12 hours ahead and the credit comes back. Later than that, the place is freed for someone else.
  • ActivityVisits, a day streak, and upcoming sessions.
  • A reminderIn the app a week before the membership ends.
  • iPhone and AndroidThe app is on the App Store, and Android members download it directly from B-Strong.

For the owner

  • Plans, memberships and session packagesWith a history of every credit used or returned.
  • Payments recordedBy cash, card or bank transfer. Members pay at the studio; the app keeps the record.
  • An overviewOf members, today’s check-ins, active memberships, this month’s income, renewals, memberships about to expire, and members without one.

What changed

Members check in by showing their phone, book their own sessions and see their visits and membership dates. Staff see who’s coming to which session, and the owner sees memberships, payments and renewals on one screen.
