Hello, 
 In Android and iOS different connections are independent from each other. You should be possible to just call connectGatt on both of them and keep to simultaneous connections. We recommend using the https://github.com/NordicSemiconductor/Android-BLE-Library/ . Each BleManager class is responsible for talking to one device. 
 Please, see nRF Blinky app for a very simple sample (only one connection at a time), or nRF Toolbox -> Proximity for multiple connections.
