been using the paid version for a bit and have no complaints whatsoever.....liked it enough that i bought the weather meter which is a no-brainer for the price(for example: if you shoot at an area with no cell service. traditional apps use the local weather station information which may or may not be accurate to your particular area. the bluetooth meter obviously doesnt care and pulls in data from your snapshot in time)
the program is as accurate as anything else ive used(trasol,shooter, Coldbore) the program is just doing the math, but its the ease of use which is the selling point for me.. i use/used it at matches and the dope was spot on to 1200. but as with any program, it will give you an answer good or bad. you give them bad info they will give you garbage back. BA simplifies things and can limit human error
the app showed its value at matches when morning temps were cool to the afternoon when it got hot and humid, used the bluetooth meter to pull in the correct DA and dope was balls on. the DA changed significantly and the speed and ease of the program are perfect for what i use it for.
i never post or comment much on topics, but this one is worth it.
the simplicity is a main point for me. i just need data, not cool bells and whistles. Ballistics Arc is the only program i use. and if you shoot matches its highly recommended.
