Use OneSignal for managing push notifications in iOS and Android

Jasonelle apps need to deliver push notifications to iOS and Android users. Implementing push natively means maintaining two separate integrations, APNs for iOS and FCM for Android, each with its own device token handling, certificate or key management, and messaging logic.

Chosen option: "Use OneSignal to manage push notifications for iOS and Android", because a single cross-platform SDK and dashboard handles token registration, audience segmentation, and message scheduling for both platforms. Positive consequences: one SDK and console to maintain, unified segmentation across platforms, and faster delivery of new messaging features. Negative consequences: reliance on a third-party service and an additional dependency in the mobile apps.

OneSignal is the best option, because it avoids maintaining separate APNs and FCM integrations and duplicates of messaging logic per platform. If "Implement APNs and FCM directly" was chosen, we would own certificate and key rotation and build segmentation and scheduling ourselves. If "Do not add push notifications" was chosen, users would miss important app updates.
