Caldwell Precision Chronograph

He has a problem with the decimals I can not just write the caliber and weight of the projectile

Worked with iPhone 7 after I bought lightning connector. Finally got a chance to use it again and showed connected but occasionally said it was not connected to iPhone 13. Seeing other reviews this has been an issue that devs refuse to fix. Had to use one shot at a time and record results. Basically a chunk of plastic without all the data perks now.

I’ve tried everything to get shots read and it will not register any shots. The chronograph works great but the app is worthless to me at this point. (Got adapter for 3.5mm jack) still no luck connecting!

Connects to iphone via official apple lightning to 3.5mm headphone jack adapter, and recognizes device in app, but does not transmit any data.

Ithe app worked great until I updated to iOS 16 and 17. Now it does not send the data to my phone…

So far this has not worked I do have a brand new iPhone 15, and a brand new iPad. It’s not working on either one some of them. Other reviews seem like it may work on older phones and iPads. I hope Caldwell will get this issue fixed to where it will work on all devices. I think it would be very nice to be able to use the app to record averages and the shot groups. Come on Caldwell get your act together.

Advertised the app all over the box. But it doesn’t work. UPDATE THE APP OR DON’T CLAM IT WORKS WITH IT !!!! Finally working without app. Found it is sensitive to amount of light coming in. So if there’s not enough light or too much ERROR or nothing shows up. By the time you finally get it to show a reading ur done shooting all ur ammo. Really disappointed with this “chronograph “ for as long as it’s been available one would think some of bugs would be worked out.

It won't pick up the chronograph via Bluetooth or plugged into my phone. Heaven forbid I have to write my velocities down. IPhone 13 mini.

It now loads with ios16 and sees the chronograph but won’t record any data from the chronograph. Was a great product but it now is useless.

On 12/27/23 I discovered that the adapter for iPhone to Chronograph was not working properly Never got the App to recognize the chronograph, connected indicator on app always Red Removed the connection at my iPhone and flipped it over and plugged it in, Indicator turned Green Repeating many times, Working one way, not the other Connection at iPhone bad or adapter connection bad, will mark adapter side that works and test in the field, Seems like the app should work now
