Very good if set up correctly

Frequent updates for new bullets ,cartridges and reticles which is great and also everything you need for a great app based ballistic program which can also link to most external Bluetooth weather stations i.e. Kestrels and others

If you have all your data correctly logged in then you have no worries to hit 6 inch target distance of 1000 yards, seem so easy. I can highly recommend using this app.
