## Version history (last 5 releases)

### 1.4.0 — 2026-09-08

- Pay at the front desk: Academies can now take card payments in person with a card reader. Memberships, store orders, and one-off charges all go through the same flow, and you get the same receipt you would paying in the app
- Save your card at the desk: Tap or insert your card once on the reader and, with your permission, your academy can keep it on file, so renewals and store pickups do not need it again
- Card readers, for staff: Set up and manage readers from Payments — connect one, give it a name, and see which are online. At checkout you pick the reader, follow the charge on screen, and can retry or cancel without leaving the sheet
- Saving a member's card, for staff: Collect it on the reader or type the details in by hand; either way it becomes their default for future charges

### 1.3.0 — 2026-08-25

- Apple Pay: Pay for your membership or a store order with Apple Pay. Your card details never leave your device, and recurring memberships are set up so you can manage them any time
- Notifications inbox: A new bell in the menu collects every announcement, class update, and billing alert in one place, with a dot when something is unread
- Flexible billing: Academies can now offer plans that bill every few months — quarterly, twice a year, or whatever interval suits them — and the full amount and schedule are shown before you pay
- Clearer checkout: Discounts and promotion codes now show the exact amount you will be charged before you commit
- Coupons, for staff: See which products a coupon applies to, and track store redemptions alongside membership ones
- Ranks: New academies are set up with standard belt systems from day one
- Fixes: Store product images no longer break over time, and the add-member and achievement sheets stay put when the keyboard opens instead of scrambling fast typing

### 1.2.0 — 2026-06-28

- Class check-in & registration: A faster, unified way to register for classes and check in — with one-tap check-in and a full-screen roster check-in for staff
- Schedule, redesigned: A floating week calendar with color-coded classes; admins can now create, edit, and delete class templates right from the app
- Run your academy on mobile: New admin dashboard, plus a full Payments hub — Overview, Plans, Coupons, Subscriptions, Cards on File, and History
- Members: Redesigned roster and member profiles with faster search and filtering, role management, a training heatmap, and recent payments at a glance
- Waivers: View and sign your academy's waivers directly from your profile
- Store: Cleaner product and order screens, with line items on Ready-for-Pickup orders
- Billing: Get notified when a subscription payment fails, and cancel past-due members immediately
- Polish: A new floating tab bar, notifications that open in the right academy, plus stability and performance improvements

### 1.1.2 — 2026-05-07

- Multi-academy: "Join New Academy" works again from the academy switcher for existing members
- Community feed: Faster, more reliable image loading
- Profile editing: Saves no longer fail silently on slow connections
- Onboarding: Added an exit hatch to recover when setup gets stuck on incomplete-academy screens
- Coaches: Edit profiles for unclaimed members directly from the roster
- Promotions: More reliable belt and stripe updates
- Stability and performance polish

### 1.1.1 — 2026-04-11

- Payments: Admins can collect payments for store purchases, subscriptions, and one-time charges directly in-app
