But is the software more accurate than other options? I don't really care if the software shows me in MY reticle, as long as it's more accurate and adjustable than other options.
Most solvers are pretty damn close to each other within first 80%-85% of supersonic flight. the transonic and subsonic data will start to show differences pretty quickly though. Say for a 6.5CM, inside 11-1200yds, if you put the EXACT same characteristics (sight height, zero range, environmental variables, velocity, BC etc) you will likely get solutions within .5MOA/.2Mil of one another out to 1200 or so. Beyond that, they can vary more quickly.
The AB software does do a few things better than some though. They have a very large bullet library with prepopulated BCs, weights, and projectile dimensions and they have the option to use custom drag curves shot through Doppler to create better flight models.
On the "not sure if it really matters" side, AB Mobile also accounts for spin drift, aerodynamic jump and Coriolis for extended ranges. Those effects are a bit debateable as to their actual influence and whether handled correctly, but I've found AB Mobile to put me inside +-.5 MOA in most solutions through 800yds with 30+ different loads/barrels and within 1MOA from 800-1100yds for never tested loads.
I like it but mainly because the interface is relatively intuitive and easy to follow. That's a big plus given some of the odd interfaces on some of the apps.
Now my primary calculator is a Kestrel 5700 AB and it is scary precise to 1100 yards. It's got a bit of a learning curve, but it works REALLY well and makes it easy to check solutions for current weather/wind.
