Cross-Platform Utility App Build

Job ID: 39817469

Budget: €250 – €750 EUR

I’m ready to turn a simple yet powerful productivity concept into a real mobile product. The goal is a utility app—think calendar meets quick notes—available on both iOS and Android from day one.

You’ll take my wireframes and feature list and craft a smooth, modern experience. I’m flexible on tech: Flutter, React Native, Kotlin Multiplatform, or separate native builds are all fine so long as the result feels fast and polished on current OS versions.

What matters most:
• Intuitive UI that follows Apple and Google design guidelines
• Local data storage that can sync to the cloud (Firebase, iCloud/Drive, or similar)
• Push-notification reminders and basic offline support
• Dark and light theme toggle

Deliverables I need at the end of the engagement:
• TestFlight build and an Android testing APK/Bundle
• Full source code in a private Git repository
• A concise README so another developer can set up the project quickly

If you’ve shipped cross-platform utility or productivity apps before and can hit an MVP in roughly 4–6 weeks, let’s talk details and schedules.
