Native and cross-platform mobile apps

The problem

Several customers needed native and cross-platform mobile apps that survived contact with App Store review, Play Store crash analytics, and real-world offline conditions. Earlier vendors had shipped apps with broken signing pipelines, unreliable push delivery, and no offline-first sync, so updates required engineering escalation every cycle and review boards rejected submissions on technical grounds.

The approach

We built apps across consumer, healthcare, and enterprise contexts on React Native, Swift, and Kotlin depending on requirements. Offline-first sync handles real-world connectivity drops; push and live activity hooks ship per-platform; in-app purchases and biometrics integrate with secure storage; the boring parts (CI, signing, beta tracks via TestFlight and internal Play tracks) are wired up so updates ship without drama. Crash analytics route to the same dashboard the team already uses.

Stack and engineering choices

• React Native + Swift + Kotlin per context
• Offline-first sync
• Push + Live Activity
• In-app purchases
• Biometric secure storage
• CI + signing automation
• TestFlight + internal Play tracks

Outcome

Updates ship from a CI pipeline; the team running the app does not need to call engineering for every release. Offline scenarios degrade gracefully; biometrics-protected secure storage protects sensitive data; review cycles pass on first submission, and crash reports surface in the existing ops dashboard.
