iSnipe – Ballistics calculator for the iPhone

iSnipe, a ballistics calculator for the iPhone is available today on the iTunes App Store.

From the website:

iSnipe is the first and only ballistics calculator for the iPhone and iPod touch. Based on the excellent GNU Exterior Ballistics Library, iSnipe generates accurate 3-DOF solutions for small arms trajectories, including corrections for pitch, yaw and wind conditions.

Simply put; a ballistics computer is a calculator used to predict any bullets path/energy/wind-drift/etc… For shooting enthusiasts, this means the ability to pre-determine how, where and at what speeds your bullets will fly, before you even load your gun.

Unfortunately it looks like the table only goes out to 300 yards, which won’t work for Boomershoot distances. And if you’re not a dumb ass like me, you can scroll down and change the max range and step size which will make it PERFECT for Boomershoot, as soon as they add temperature and pressure. (See Joe’s comment below)

UPDATE: Yes, it is funny that something with “snipe” in the name only goes to 300 yards.

UPDATE:  HA HA the joke’s on me.  Did you know the iPhone has a scroll feature?   If you scroll down on the settings page you can change the max range.

    I’m not seeing any way to input altitude and temperature either. Without those it is barely useful out to 300 yards.

    I don’t have an iPhone or iPod Touch so I have no way of verifying the deficiencies. I just looked at the screen shots.

    The GNU Exterior Ballistics Computer does do pressure and temp, so maybe the iPhone version will soon.

    OK, so that’s what I get for not looking closely. Max range appears to be 6000 yards.

    The results don’t match Modern Ballistics for sea level, 59F (standard conditions for ballistics calculations). Maybe they used some other environmental conditions as the default. It’s “close enough” out to about 500 yards but by the time you get to 1000 yards it’s off by almost two feet. They could be using an outdated algorithm too. When I researched it 10 years ago all programs except for one other used inferior algorithms and it had a terrible user interface.

    I emailed the developer and got this response:

    “indeed, atmospheric corrections will be out in our next release… Shouldn’t be very far off now.”

    So they’re still working on it.
