Three tabs. One client book.

Calendar, clients, and finance — three tabs, one local database on your iPhone or iPad. Scheduling is free forever; finance unlocks with PRO.

Day, week, and month

Your local schedule — client bookings and personal time blocks on one calendar, stored on device.

  • Day, week, and month views with color coding and working hours
  • Client appointments and personal events — both free
  • Multiple services per visit with custom price and duration
  • Statuses: booked, completed, cancelled, no-show, partial payment
  • Repeat appointments, per-visit notes, drag to reschedule in day and week views
  • Overlap conflict hints — no server sync required
  • Local push reminders for you; client message drafted automatically — one tap to SMS, Telegram, WhatsApp, Viber, or Instagram, and you send it
