RevenueCat made setting up in-app subscriptions across iOS and Android super simple. The SDK handles all the messy store logic and gives you a clean way to manage pricing, offerings, and entitlements. Also, I love the virtual paywalls — makes testing feel like magic.
Firebase gave us an all-in-one backend solution — auth, real-time database, and analytics — without the overhead. It let us stay lean and focus on building the user experience.
Expo made it incredibly fast to prototype, test, and deploy BeRoomie. The managed workflow saved me tons of time compared to native setups, and the EAS build system is a game changer.
