Functionality needed the app: 1. After call evaluation ("hot or not" slider with 10 steps) with saving evaluation data to contact 2. Easy creation of call reminders (to calendar) 3. Scheduled calling list, ability to re-rank contacts 4. Settings - user able to change reminder settings and calling list prioritization rules 5. Launching other functionality: calling, contacts, calendar, mail, sms, voice recorder 6. Notifications Optional: 7. Option to sync contact/-history data with server 8. Publish to Appstore The UX should follow iOS7 design guidelines and the graphics should be easily changed. The generic UI pictures available (not yet per OS). The performance should be at the level of native app. This is the first test project, we have plenty of app ideas in the pipeline including gaming&simulations. We are looking for efficient developer(s) with the experience of developing and publishing several iPhone apps, for whom we can outsource end-to-end development work. Experience on other major platforms (Android, WP8 and Bada) is a plus.
