I turn a mobile product idea into working screens and a testable build. The starting scope covers one core flow with up to five screens for one agreed platform, iOS or Android. I design the interface, implement the flow, connect one agreed API where needed and test the build. You receive the source, build instructions and a documented handover. Two consolidated revision rounds are included. My work includes Personal Palmist and TABUNO, my released iPhone physics game. A second platform, additional integrations and store submission support can be scoped with the project. Send your goal, references, existing assets and target date. We agree the deliverables and schedule in writing before production. The displayed price covers the starting scope. Additional work is quoted after the brief is reviewed. The displayed duration is an indicative planning window. Delivery dates are confirmed after the brief and assets are reviewed.
