Great Improvements Made

I was reluctant after reading the reviews to download this app, but after looking at the update history I decided to give it a try. It has worked flawlessly and is very easy to use, including with the Apple watch.

This app developer has worked incredibly hard to address all the negatives brought up in past reviews. Every update is something major that makes a huge improvement in functionality. A year ago I wouldn't have recommended it, but today I say buy it with complete confidence.

Not Recommended

Don’t get me wrong. It is a beautiful app and well put together. But if it doesn’t have your specific reticle it’s useless. Purchased a few months ago, requested my scope reticle be added and have sent an email. Last update was over 3 months ago. Developer has not added reticle or ever contacted me back. Will not be recommending to my students. Look elsewhere for a ballistics calculator.

A good start to a great potential

This app could be great but alas it’s missing the ability to share load data between devices and it would be great to get all the data organized in the phone and share it to the watch as well as being able to link the phone and the watch so you could gain duel access to the same info in real time with the phone and the watch.

The dogs are barking down here for more Apple Watch compatibles.

Thanks for being the fist to make it happen

Woof woof
