I want to bring a brand-new productivity application to life on Android. The scope covers everything from refining the initial concept and wireframes through coding, testing, and publishing the app on Google Play. The core idea is simple: help users organise their day more efficiently, and do it with a clean, intuitive interface that feels at home on current Android versions. You will take charge of the full development cycle, advise on best-practice architecture, and keep performance snappy even on lower-end devices. Kotlin (or modern Java) in Android Studio, Material Design components, and a reliable cloud back-end such as Firebase are the tools I expect to see in the stack, but I’m happy to discuss reasonable alternatives if they achieve the same result. Deliverables: • Production-ready APK plus signed AAB for Play Store submission • Complete, well-commented source code and build instructions • Brief technical document outlining architecture, third-party libraries, and any API keys that need replacing before release Acceptance criteria: • All primary user flows tested and bug-free • UI scales properly across common phone and tablet resolutions • App passes Google Play review without policy violations If you have a portfolio of Android apps—especially productivity tools—please mention them when you reply so I can see your style and code quality. I’m ready to start as soon as we confirm scope and timeline.
