Build an app like get-trackr.io - for tracking via BLE beacon technology

We need an ios app and an android app like the one used by [login to view URL] The app should read BLE data transmitted by the beacons attached to the app. Other features: App should show signal strength of each attached beacon. User should be able to attach more than 1 beacons to one app. App should show position of the beacon on a map It should trigger an alert/notification when any attached beacon is separated from the app - goes out of range or stops signaling It should show last known position before the beacon was separated The app should be able to trigger the ringer on the beacon. Conversely, a push button on the beacon should be able to trigger the ringer on the phone If a beacon is reported as lost then that beacon should be attached to all apps installed on all smart phones. Any other feature you see in the original trackr app. See the app and also the videos of the app posted on their site. Our beacon will be standard ble beacons that will emit in both formats : ibeacon and eddystone. It will have a ringer which can be activated and deactivated via bluetooth signals and will also have a button that will send a bluetooth signal that the app will sense and start ringing. The tracking, mapping, last known good position, alerts/notifications will use standard protocols/formats of ibeacon and eddystone whereas we will give you additional info about the 2 way ringer. All communications are local bluetooth except for the lost beacon reporting which needs internet connectivity. And of course the mapping feature which might require access to google maps.
