Use native calendar APIs (EventKit for iOS, Calendar Provider for Android) for two-way sync and send push/SMS reminders (24h & 1h before) via FCM or OneSignal. Add an “Add to Calendar” button after booking for easy user access.

Optimizing mobile app performance without sacrificing user experience requires a balanced approach during mobile app development. Start by streamlining your app architecture—minimize unnecessary background processes, optimize API calls, and implement efficient caching strategies. Using lightweight code, compressing images, and adopting content delivery networks (CDNs) also help improve load times.
