Received this as part of a gift package...but I don't have an Android phone, so it's no use for me. Seems like a great concept for an inexpensive shot timer. New in Bag. $20.

The RangeTech Shot Timer plugs into your phone's 3.5mm audio jack and interfaces with the RangeTech App to provide the world's most affordable, reliable, and feature rich shot timer.
The Android (3.5mm Jack) version is available for pre-order now and will be shipping soon!
The iOS (3.5mm Jack) version is currently being finished up and we will also be working on special versions for lightning and USB C ports, given sufficient demand.
*The RangeTech Shot Timer is NOT currently supported on phones which require an adapter for 3.5mm audio devices.
