Instructions need work. Following the manual included with the Chronograph resulted in about a half hour of failure. After restarting the app, reinstalling it, and reading comments and faqs, I nearly gave up and started to send the Chronograph back. I decided to try one more thing, and that was hook the Chronograph up to power via the USB port. After that, everything worked flawlessly. The device powered up, and the app worked. Just had to figure it out on my own.

App is garbage. Chrono doesn't work. Connects to Bluetooth then disconnects. Only thing that works in app is their store to order more products. Save your money. If you want a chrono, just buy a chrono. If anything changes I will update my rating. Much less expensive tracer units on the market.

The simple knack of making this connect on BT, is to allow the app access to location etc as per it's default requests. I've set mine to only do that when the app is running, so I need to go through these two steps every time I start it up, but only takes one or two seconds. You can save ammo types if you have at least one recorded shot for that type. Don't stick the muzzle right up against the adit, or it will give false readings. Allow 100mm / 4 inches clearance or so. Works well for me.
