Add Features & Upgrade App Functionality

My current app is solid but feature-thin. I’m ready for a full upgrade that introduces brand-new capabilities while elevating the underlying functionality end-to-end. The brief outline is simple:

• New features: this is the priority. Tell me what’s technically feasible, then build it.
• Functionality overhaul: refactor or extend the existing code so the new features run smoothly, scale well, and don’t break what already works.

Process I have in mind
1. Audit the present build and document the gaps.
2. Propose an implementation plan with milestones.
3. Code, test, and integrate each feature incrementally (unit tests + user acceptance).
4. Final hand-off with updated source, release builds, and a short knowledge-transfer session.

You’ll get full repository access and any current documentation the moment we agree on the scope. I’m flexible on tools and frameworks as long as the final product is reliable, easy to maintain, and meets store submission guidelines.

If this sounds like a challenge you’re ready to tackle, walk me through your approach and a realistic timeline and we can get started right away.
