iOS & Android Stock market Tips App

I’m building a mobile application that delivers short, actionable tips and suggestions to users and I want it released simultaneously on the App Store and Google Play. The content already lives inside our CRM, so the app has to fetch new tips, push user activity back, and stay fully synced without manual intervention. All CRM communication is available through a REST-based API and secured with OAuth2.

A clean, lightweight UI is the priority—think scrollable feed, category filters, quick search, bookmark, share, and the option for scheduled push notifications so a new tip can land on a user’s device at set intervals. I’m open to native Swift/Kotlin or a robust cross-platform framework such as Flutter or React Native as long as the final builds meet Apple and Google submission requirements.

Key deliverables
• iOS and Android binaries ready for store submission
• Well-structured, documented source code in a shared repo
• Secure integration layer that authenticates to our CRM and keeps content in sync
• Basic analytics and logging routed back to the CRM for user insight
• Handover documentation and a quick walk-through call

Acceptance criteria
• Tips load from the CRM within 2 seconds on a typical 4G connection
• Offline caching for at least 50 tips
• No critical or high-level issues flagged during App Store / Play Console review
