Gojira BJJ is the all-in-one membership app for your Brazilian Jiu-Jitsu gym ā built for students and instructors who want check-ins, schedules, and billing in one place instead of a clipboard and a spreadsheet. FOR STUDENTS ⢠Check in with a single QR scan at the front desk ā no waiting at a counter. ⢠See your belt, stripes, and attendance history at a glance. ⢠Browse the weekly class schedule and know exactly when your groups train. ⢠Get a heads-up before your membership or class allowance runs out, with a one-tap renewal. ⢠Buy or renew your plan right from your phone, including bank-transfer payments for gyms that don't take cards yet. ⢠Available in English, Georgian, and Russian. FOR GYM MANAGERS ⢠One shared QR code handles check-ins for every member ā the app flags expired, inactive, or over-limit visits automatically so nothing slips through. ⢠A week-at-a-glance check-in view shows who trained today, with a full calendar for history. ⢠Manage your full roster: add members, edit belts and plans, verify new sign-ups, and track who's about to expire. ⢠Build and edit your class schedule, with attendance automatically attributed to the right session. ⢠Offer public membership plans to everyone or private, personalized pricing to specific members ā sibling discounts, loyalty rates, one-off deals. ⢠Confirm or reject pending bank-transfer payments from a dedicated queue. ⢠Dashboard statistics for attendance trends and revenue at a glance. Gojira BJJ replaces paper sign-in sheets, group chats for schedule changes, and manual billing tracking with one app your whole gym actually uses ā instructors keep a clear picture of who's training and who's about to lapse, and members always know where they stand
