I have an android phone and I have been using the Shooter App.
There hasn't been an update available for years and I wonder if there's something better out there.
It must be able to store data for multiple rifles, some rifles with multiple loads.
Ideally have a GPS setting for altitude and (approximate) wind speed.
Needless to say it must be able to calculate corrections in MOA and MIL, for elevation and windage.
What is everyone using?
