I currently have a utility/tool app live on both Android and iOS and would like a confident mobile developer to help me take it to the next level. The exact focus—be that refining the user interface, boosting performance, or rolling out a small set of new features—will be decided together once you have reviewed the existing codebase and store listings. What matters most right now is clear, measurable improvement that users will feel the moment they open the app. If you are comfortable auditing an existing project, suggesting practical enhancements, and then implementing, testing, and submitting the updated builds back to each store, this should be a straightforward collaboration. Deliverables • Short audit report highlighting agreed areas to improve • Clean, well-documented code changes • Updated Android (AAB/APK) and iOS (IPA) builds ready for release • Brief hand-off notes so future maintenance remains simple Please include a link to at least one utility or productivity app you have upgraded or maintained, and let me know which tech stack you prefer working with (native Swift/Kotlin, React Native, Flutter, etc.). I’m ready to start as soon as we align on scope and timeline.
