I highly recommend Ballistic AE. Its $20, but after using if for several years now, I trust it to be accurate out to 1000 yards. After using the velocity correction feature offered in the app, I am confident in making 1st round hits on target (as long as I do my part reading the wind), out to 1000 yards (farthest I have actually used the data from the software).
