Problem

Independent service masters (barbers, nail artists, stylists) needed a calendar that fits a one-person business — booking, prepayment, no-show protection, push reminders. Generic SaaS tools were too heavy and too expensive.

Approach

  • 01SwiftUI from day one — a single codebase that scales from iPhone SE to iPad without per-device branches.
  • 02Firebase Auth + Firestore for low-ops persistence; security rules co-located with the data model.
  • 03StoreKit 2 in-app subscriptions, paired with server-side JWS verification (see backend case) to prevent revoked-receipt fraud.
  • 04FCM for booking and reminder pushes; Crashlytics for production triage on a real-device-only test loop.

Outcome

Shipped to the App Store on 2026-05-10 in 102 regions (US, Canada, LATAM, most of Europe, Africa, ME, Asia-Pacific). $0.99/month subscription with a one-month Apple Introductory Offer. Android port (1:1) is the next platform.
