Applied Ballistics Mobile app

Introducing the Applied Ballistics (AB) Mobile app.



This state of the art ballistics program is currently available for android devices (it will be developed for iPhone/iPod in the future).

The AB Mobile app:
Accounts for all major and minor trajectory variables
Pulls in weather data and latitude from GPS or blue-tooth link with Kestrels.
Has a library of (Litz) measured G1 and G7 BC's
Features custom drag curves for specific bullets as in-app purchases ($1.99)
Displays single shot solution in HUD view or Reticle view
Displays multi-shot solution in Reticle view, table, and graph
Offers Ballistic Calibration, so you can enter your observed drop at range and the program will calibrate; muzzle velocity, projectile drag (BC), and drop scaling over various segments of the trajectory.
Web-sync feature which allows you to store your rifle/ammo libraries online for quick retrieval.

For those familiar with the Shooter app for android and iOS, the AB Mobile app is basically an extended/advanced version of Shooter. AB Mobile was programmed by the same developer, and uses the same solver, but has a number of additional features that extend capabilities and interfacing beyond any ballistics app currently on the market.

You can view the user manual here

The app is available for purchase in the Google Market

Here are some screenshots of the AB Mobile app:









Please post any questions, comments, requests, etc to this thread.

Re: Applied Ballistics Mobile app

Bryan , so this program is using G1 or G7's to model?

Jeff,

With this program, you can use G1, G7, or custom drag curves to model drag for specific bullets.

Re: Applied Ballistics Mobile app

Ok, and am I correct that in the Ballistic calibration it will modify not only the muzzle velocity but also the BC of the bullet to get a perfect ballistic match from your actual field drops?

What I mean is does it work with both or do you choose which you wish to modify?

Thanks
Jeff

Re: Applied Ballistics Mobile app

Jeff,

When you're using the ballistic calibration, it forces you to calibrate MV from zero to a given range window (high transonic), then from there to the next observed drop point (low transonic) it calibrates drag. This method and the ranges are optimized to calibrate the solution in the context of Mach number. Beyond transonic range, the solution simply scales drop, but that's beyond the ranges most will encounter.

If you really want to 'calibrate' BC/drag from muzzle to some range, you can do it manually, the old fashioned way. But the ballistic calibration interface was set up to force users to do what is usually the right thing. The original version allowed more flexibility but in testing it was found that users did many things wrong thru lack of understanding and ended up with worse solutions than they started with. So we enforced some policies to promote better use and results.

Re: Applied Ballistics Mobile app

For the iPhone version, realistically how long into the 'future' do you imagine it will be before we see a release?

Re: Applied Ballistics Mobile app

blackdog,

Honestly, it's going to be a while. We have a priority before iPhone, which is to develop a fully functional website that allows you to do all the same calculations as the mobile app, which will sync with the mobile app as well.

The iPhone version is next on the list after the webpage.
