Fitness Industry Challenges
Most fitness clubs keep member data in spreadsheets, post schedules on walls, and track memberships in legacy billing software. When a member wants to check if spots are open for Friday yoga at 7 PM, they have to call. Progress tracking doesn't exist. Worse, clubs lose contact between sessions: no class reminders, no motivation to return after a miss.
- Churn due to inconvenience (members don't know schedules, can't book ahead)
- Manual class registration management and overcrowded sessions
- Missing attendance and progress data
- Complex membership and freeze management
- No direct member communication (reminders, news, promotions)
- Poor trainer availability and schedule change visibility
What We Build
A native app (iOS and Android) with member portal and admin dashboard. Designed for mobile-first: book in seconds, view schedules, check membership balance, receive alerts.
- Personalized schedule with filters by trainer, class type, day
- Live seat availability and instant booking
- Member portal: membership balance, visit history, expiry date
- Push notifications: class reminders (30 min before), schedule changes, promotions
- Trainer ratings and member reviews
- Integration with your membership management system
- Admin dashboard: schedule uploads, capacity management, in-app messaging
- Dark mode, multi-language support (Russian + English)
Integrations and Club Management Systems
Most fitness clubs already work with membership management and admin software. The app must sync with these systems so all data stays current and manual work disappears. We integrate with popular platforms and can connect your custom system via API or CSV import.
| System | Integration Type | What Syncs |
|---|---|---|
| MindBody, Fitmost | Direct API connection | Members, schedules, memberships, payments, visits |
| ERP systems (club systems) | API or file exchange | Services, prices, memberships, class inventory |
| ClassPass, Zenfit | API integration | Cross-pass members, compatible classes |
| Custom system | Custom API development | Full sync per your logic |
| CSV/Excel import | Periodic uploads | Members, schedules, rates (daily updates) |
Analytics and Success Metrics
The app isn't just convenient for members; it gives your club analytics tools. Admins see which classes are most popular, who attends regularly, and who's at risk of leaving. Use this data to shape strategy: add popular class types, remind members who've gone silent, offer them special deals.
- Attendance by class: which trainer and class type are most popular
- Member activity: daily, weekly, monthly stats (active members per period)
- Churn risk: system identifies members who haven't visited recently, triggers re-engagement
- Capacity tracking: percent full per class, peak and slow hours
- Trainer ratings: scores, reviews, results photos
- Financial metrics: ARR (annual recurring revenue), churn rate, member LTV

Features by Implementation Phase
You don't need every feature on day one. Start with an MVP (minimum viable product) with core features, then add more. This way your club sees results faster and we get real member feedback.
- MVP (3-4 weeks): schedules, booking, member portal, push notifications
- Phase 2 (2-3 weeks): analytics, trainer ratings, visit history, payment integration
- Phase 3 (4-6 weeks): member social (chat, results photos, challenges), video lessons, training plans
- Phase 4 (optional): trainer portal (schedules, student list, reviews), loyalty programs (points, rewards)
Security and Data Privacy
The app handles sensitive member data: names, phone numbers, contacts, payment info, visit records, and health information. This must be protected. We use modern encryption and comply with Russian personal data protection laws.
- Data transmission encryption: HTTPS, SSL certificates
- Password storage: hashing with salt, original password unrecoverable
- API tokens: each session protected by time-limited tokens
- Two-factor authentication: optional added security for admins
- Audit logging: all admin actions logged for compliance review
- Russian compliance: full adherence to Federal Law data-protection law (GDPR) on personal data
Project Timeline
- Discovery (1-2 weeks): interviews with staff, workflow testing, integration platform selection
- Design (1-2 weeks): wireframes, mockups, navigation prototypes, approval
- Development (4-6 weeks): iOS and Android frontend, API, integrations, localization
- QA (1 week): functional testing, bug fixes, performance checks
- Launch (1 week): App Store and Google Play submission, member onboarding, staff training
- Support: OS updates, hotfixes, ongoing monitoring
