Custom App Development

We need an Android and Iphone app. We already have a draft design for it, need it to be built. As we are located in Singapore, we prefer to have someone stationed locally for easier communication. We need the following app functions: (Possible to break down into various stages of development) - able to track multiple wearable devices with GPS and show on map (similar to friend finder or life360) - able to merge and reflect wearable device info on the app, for example, if wearable device has a heartbeat sensor, the app is able to reflect the current heartbeat, and if exceed certain rate, a notification can be sent. - enable members of public to take geo-location pictures and report certain issues to us, in which the owner of each issue will receive a notification and a map showing where the issue is located - app to have points system where user can score points by participating in various functions of the app, or purchasing from selected merchants - points can be converted to vouchers or discounts to be used at selected merchants. (We need recommendations on how to smoothen the flow of this, user buys something from merchant both online and offline, user gain points, points to redeem more discounts online and offline.) - prefers to avoid any manual input from both consumer and merchant side, to be as hassle free as possible. - appointment booking system via app, where consumers can view merchants’s available time slots and submit an appointment. (Need recommendations or advice if possible to integrate merchant’s existing calendar into app, to reflect busy time slots as greyed out area) Please feel free to quote us a suitable price or ask any questions.
