Mobile development

I need an iPhone/iPad app. I already have a design for it, I just need it to be built. I have designed an app and need a developer to develop the app to run on iPhone and Android, based around recording events and data. I ideally require a developer with React Native experience to develop on that platform. App Summary The project is essentially an app that provides a diary like experience for tracking events, reservations and related data. Like a calendar, but with specific types of appointments at locations and times, follow-up appointments and recurring appointments. In addition the results of those appointments will entail entering and storing data, either on the keyboard or via the camera. The overall intent is to provide a specialised data store to enable the user to track historical events, data surrounding them and their outcomes. Initially it will be self-contained on the phone/tablet but needs to be able to provide for storing and syncing the data to an online store. Happy to answer any questions. I am after a developer for the initial prototype. Costs are for this phase.  We can discuss then the next phase. I have a detailed PDF of the design I can send.  Paul O'Rourke
