Project description:
"I’m ready to move from concept to code on a brand-new productivity mobile app that will run smoothly on both iOS and Android. I have the core workflow sketched out and now need a developer who can take ownership of the full build—from setting up the architecture through store-ready releases.

Here’s what I have and what I’m expecting:

• Vision & wireframes: high-level screens that capture the core productivity flow (task entry, quick edits, smart notifications, and a focused dashboard).
• Tech freedom: I’m open to React Native, Flutter, or another cross-platform approach you prefer, as long as the final experience feels native on each platform.
• Backend: a lightweight, secure API (Firebase, Supabase, or your suggested stack) to handle user accounts and cloud sync.
• UX polish: fluid gestures, offline caching, and small interactions that make the app feel snappy and professional.
• Deliverables: complete source code, documented setup instructions, staging builds for TestFlight and Google Play Console, plus a short handoff call or video explaining the project structure.

Acceptance criteria
– Both apps install and function without crashes on current iOS and Android releases.
– Core features mirror the wireframes and meet Apple/Google store guidelines.
– All code is lint-clean and pushed to a private Git repo with clear commit history.

If this is in your wheelhouse, let me know your preferred framework, any similar apps you’ve shipped, and a rough timeline to get to MVP. I’m happy to answer questions and share the wireframes as soon as we connect." (client-provided description)
