On Point Ballistics (Free)

On Point Ballistics is the most advanced and convenient ballistics application available for the Android platform.

Free Version
This is the free version and has a slightly reduced feature set compared to the full (Paid) version. This app is completely functional as is, but does not perform some advanced ballistics calculations such as spin drift and Coriolis calculations. For many ranges the difference is not noticeable but at very long ranges you will want the advanced ballistics features of the paid version.

Store your Firearms and Load Library
On Point will keep track of your firearm and load libraries. No need to re-zero to the load. Just note the point of impact if your groups for a given ammo from your rifle without dialing any elevation or wind in your scope and On Point will tell you what you need dial for any range and any condition.

Simple Mode to Get You Started
The free version of On Point is limited to simple mode only. The ballistics solver accurately accounts for weather changes such as pressure, temperature, and humidity changes. The Advanced mode (Available in the paid version) can also account for the effects of spin drift, Coriolis, and powder temperatures.

Tracks Weather for your Zero Conditions **(Paid Only)
On Point goes above and beyond other ballistics apps by allowing you to record the weather conditions on the day you zeroed your load, and account for weather changes from from your zero. This means you can zero your rifle at sea level and maintain long range precision on even in the thin atmosphere of the high mountains.

True Muzzle Velocity Calibration
It also has a tool to help true your muzzle velocity to your drop calculations. By inputting observed drops at known distances On Point will calibrate your load to a true muzzle velocity, making certain that the drop it predicts is what you'll get in real world shooting.

Powder Temperature Sensitivity **(Paid Only)
Most powders will burn faster when at higher temperatures, meaning you'll get a bit more muzzle velocity from you rifle when your ammo is hot compared to when cold. Just note the temperature of your ammo when you zero your rifle ( probably close to the outside temperature ). This means that you can zero your rifle in the mid summer heat and have confidence in your shots during the freezing winter hunter seasons.

Optional Weather from the Internet
If you allow internet and location permissions On Point can use this information to look up and input the local weather conditions. Don't like giving these permissions to apps on your phone? No problem, On Point will operate just find without them. Just type in the conditions manually if you want atmospheric and Coriolis corrections.

Built In Projectile Library
On Point comes standard with a ballistics library for over 250 of the most common projectiles in use today. This means that it is very likely that you won't need to look up any ballistics coefficients, just look up your projectile in the ballistics library. NOTE: The library only lists projectiles for your rifles caliber when editing a load. You should make sure for example that if you're setting up a load for a .270 Winchester, you set the rifle and load caliber to 0.277. Set it to .284 caliber for a 7MM magnum, etc. etc.

Hit Probability Estimation **(Paid Only)
One feature that On Point has that puts us ahead of the other ballistics apps on the Android market is the ability to do Monte Carlo shot dispersion. In simple terms it means we don't just calculate one firing solution, but hundreds, each one slightly different based on the known variances in your shooting setup. ( Load group size, standard deviation of muzzle velocity, the uncertainty in your wind estimation, and the uncertainty in your range estimation). When simulating many rounds On Point can estimate the likelihood of a hit under the given conditions.
