For you iPhone lovers and users you might want to check this out. Its way out of my league for use. I'm still using a Treo.
Ballistic (http://ballistic.zdziarski.com/) is a fast, highly-accurate ballistic trajectory calculator and range companion for the iPhone. Ballistic calculates trajectory, windage, velocity, energy, and bullet flight time for any valid range, and can compensate for atmospheric conditions such as temperature, barometric pressure, humidity, and altitude. It's also much more than a basic trajectory calculator. With a vast library of over 1,500 projectiles, range estimation calculator, GPS and atmosphere awareness, and a range log, Ballistic is a complete mobile companion for hunting or at the range.
Features
How Ballistic crushes the competition...
An Expansive Ballistics Library
Select from a library of over 1,500 projectiles from leading manufacturers, military projectiles, or specify your own projectile properties. Library includes the latest 2009 commercial projectiles and military coefficients from Aberdeen Proving Grounds. Just select your bullet diameter and all of the available projectiles will appear, sorted by manufacturer.
One-Touch Atmospheric Correction (Core Location)
Correct your calculations for the current atmosphere by pressing the Core Location button. Your altitude, standard pressure, temperature, relative humidity, and wind velocity will be automatically set based on your current location and information from the NOAA National Weather Service (or optionally, GeoNames). A global setting allows you to set which fields are updated. Manual entry can also be made.
Bookmarks
Bookmark your favorite calculations and recall them later, or load them back into the ballistics calculator to tweak them or generate charts.
Angular Acquisition
Aim the iPhone at the target like a remote control, then press the LOS Angle table cell. After a three-second countdown, the table cell will be updated with the correct shooting angle to the target based on the accelerometer reading. A preview label displays the angle prior to capturing it. The angle can also be inverted by 90° making it suitable for use in a weapons mount. The HUD (Field Tactical Edition only) automatically locks onto your current angle and updates your calculations every second.
NOTE: The iPhone and iPod Touch are not recoil rated, and it is not recommended that you fire while the device is attached without a recoil-rated case
Ballistics Charts
Ballistics charts allow you to display the energy, velocity, and drop for your current projectile, or compare up to eight projectiles together on the same screen. Your current atmosphere and zero are automatically applied to all projectiles, so you're comaring apples to apples. Compare bullet path and energy or wind drift. Ballistic will also show you trajectory charts based on altitude or shooting angle. Zoom up to 300% or save a full size chart to your photo library and transfer it to your desktop.
Variable (Stepped) Ballistic Coefficients
Support for variable (stepped) ballistic coefficients for many popular projectiles including Sierra MatchKing®, GameKing®, and ProHunter®. Variable coefficients allow for more precise calculations and overall better accuracy by adjusting the bullet's flight to fit the commercial G1 drag model. Ballistic also supports all G1-G8 drag models.
Drag Model Conversions
Automatically convert between two different drag models. Ballistic will recalculate the ballistic coefficient and adjust its trajectory to fit the new drag model. This is ideal if you only have a G1 coefficient for a VLD, spire point, or other type of uniquely-shaped projectile, as it allows you to apply a more accurate drag calculation. This may improve your long range accuracy beyond that of the standard G1 calculation provided by the manufacturer.
Minimum and Maximum Point Blank Range
Ballistic automatically calculates your minimum and maximum point blank ranges based on your zero and the vital zone radius you specify, and will display these in the form of red arrows.
Full Metric Support
Global settings exist to change the units of measurement for distance, atmosphere, and all other units. This includes bullet drop, altitude, sight height, wind speed, temperature, pressure, velocity, and energy. Favorites are automatically converted so that you can retain your zero and atmosphere, but appply the same calculations to either yards or meters. In other words, your favorite will stay zeroed at X yards, and give you accurate output for Y meters, and vice-versa.
Elevation and windage output can also be specified in In, Cm, MOA, MIL, and click values: 1/8 Minute Clicks, 1/4 Minute Clicks, 1/2 Minute Clicks, and 1 Minute Clicks. A custom click value can also be provided for scopes with nonstandard MOA click values. When in metric mode, the inches column automatically changes to centimeres. A global preference selects between USMC and Army Mil-Dot specs.
Mil-Dot and MOA Distance Estimator
Calculate distance using Mil-Dot or MOA reticles. Supports conversions including inches, cm, feet, yards, and meters.
Range and Scoring Log with One-Touch Notes
Range log to keep a journal of all your hunts, shoots, adjustments, points of impact, and scores. Touch the Core Location button to automatically fill in your current coordinates, which you can later recall into the Maps application. Query the NOAA National Weather Service for local atmospheric and weather conditions. Range log can automatically tally your target data cards and even keep track of your X's. Choose from a variety of targets including standard, F-Class, pistol, silhouette, archery, buck targets, and more. Different targets for zero data cards are also available. As of v1.4, use your zero data log enries as a source to set your calculations' zero atmosphere.
Very fast and precise calculations, even at long range
Ballistic undergoes heavy testing and comparison with known data, and has satisfied many in accurately reflecting true-to-life trajectory. It compares very well to well respected ballistics packages such as JBM and Sierra's Infinity suite.
