DAA EDGE Shot Timer

The app was completely unusable, it kept crashing within 10 seconds of launching. reached out to the developer with no response.

I'm enjoying the timer and it's interface. One issue is the Bluetooth times out too quicky when disconnected from a Practiscore app. The iPad tablets we use at our range will go to standby mode movinge between ranges and the DAA Edge will turn off Bluetooth after about 5 mins. Then we needs to do a whole resynching process to turn the BT back on in the DAA Edge timer. Can the BT time out after 15 or 30 mins?
