External ballistics calculator for iPhone: iSnipe


iSnipe is a very polished looking external ballistics calculator for iPhone / iPod Touch created by a Canadian firm.

Created with ease of use in mind, iSnipe is the perfect companion for any gun aficionado, competition shooter, or even law-enforcement officer… It’s just that accurate. With all the ingredients you’d expect from a portable ballistics calculator, including the ability to save and load ballistic profiles, automatic save of form values and all the other features you’d expect from an integrated iPhone app, there is no better way to get on target every time. Finally there is a portable desktop quality application that we can all take along with us to the range.

A Palm OS Calculator for comparison.
I was a palm fanatic back in the day.

According to Joe Huffman, the current version does not include the ability to set altitude or temperature these features will be available soon (See update below).

A couple of weeks ago I predicted this application would be available soon (not a hard prediction to make considering there is a ballistics calculator for just about every mobile platform invented), now just waiting for my other prediction, a full IPSC timer.

UPDATE: iSnipe has been updated and how includes many new features including temperature, weather conditions, air pressure etc.

    I’m pretty sure .303 NATO is supposed to be .303 British. It was used for the Lee-Metford, Lee-Enfield, and the Japanese clone version in WWII.

    I have a milsurp Lee-Enfield No4Mk1 and can say that is a fairly remarkable round. Accurate and easily penetrates 1/4 steel plate at 30-40 yards. The weapon sighting system itself is calibrated between 200 and 1300 yards using the micrometer sight and 200 yards using the battle sight.

    I have looked at various calculators – some better than others. Humidity is a factor that is taken into account by some. However, I’ve never seen any allowance for precipitation. I’ve asked around and never found anyone who had heard of such a thing. I have a friend who was in Special Forces and was the “shooter” for his team and he hadn’t heard of making an allowance.

    However, it seems to me that air with some precipitation, but not enough to obscure the target would be more dense than air that was just 100% humidity. Am I out in left field on this?
