Determine your individual klick-values (ballistic turret) resp. correction values (distance reticles) according to
- Your riflecope (including your personal settings)
- Ammunition (choose from a database or enter manually)
- Atmospheric conditions and
- Shot-specific factors (zero range, angle shot, type of target)
- Calculation of ballistic coefficient (BC)
- Expert-mode for atmospheric conditions
- Display of trajectory table (incl. windage)
You can quickly and smoothly convert between angle, target size, and distance to target.
This app can be used to:
-Calculate accuracy based on grouping size at given distance
-Help calibrate precise scope adjustments with no guesswork
-Estimate minutes of arc (MOA) and milliradians (mils) without bulky conversion charts or tricky equations
-For fixed-power or FFP mil-dot scopes, easily compute the distance to a target or estimate the target’s size if distance is known

Bullet weight is a component of the ballistic coefficient!
Good for handgun, rifle, and shotgun reloading
Save and load information for easy storage and retrieval
The reloading Data Viewer/Tracker is used to get load data (or recipes) for many different calibers. You can also add custom loads, as well as track how well each round performed by rating the accuracy and power of the load, as well as keep comments for each load.
Featuring load data from:
Accurate, Alliant, Hodgdon, Somchem, and Vihtavuori.
Many calibers and thousands of preloaded data already in this program with more to be added daily/weekly!
Upgrade to the paid version to save multiple firearm profiles and custom ammo.
- Includes a built-in ammo database of over 1400 rounds
- Generate a table of calculated shot data
- View drop graphs and compare ammo
- Accuracy verified by comparing drop to bullet manufacturers' published data
- Simple touch input for setting wind direction
- Supports imperial and metric units
- Upgrade to the paid version to create multiple firearm profiles and save custom ammo
** Tips **
- Before using the calculator for the first time, zero the default firearm profile
- Negative drop means the bullet impacts below the aim point
- Negative drift means the bullet impacts to the left of the aim point
- Edit the firearm profile from the main menu or by clicking the pencil icon in the action bar
- To use MOA in the table, select MOA as the output units on the main screen
Conversions - unit to unit:
* Weight: grams grains ounces pounds
* Speed: mps fps
* Dimensions: mm cm m in ft yd
* Bullet energy (Joule and ft-lbs) calculator
* MOA & MRAD calculator from units mm, cm, m, in, ft, yd
* Graphical mil-dot range finder to estimate range to target using mildot reticle and target's natural size. Supports metric and imperial units.

Knight's Armament BulletFlight is a military-grade ballistic computer that provides quick solutions in the field. BulletFlight does not output information in table format but rather dynamically gives you the solution you need now to make that shot. Current weather conditions including temperature, pressure, humidity, wind speed, and wind direction can be input, as well as angles to the target as measured by the built-in accelerometer. The app then provides highly detailed solutions out to 3000 meters. Your weapon profile includes your scope MOA/mRad per click, and hence when you provide a range to the target, the app will simply show how many clicks you need to change the scope by for that range and wind speed.
Includes over 1400 projectiles including carefully-measured G7 BC database for VLD bullets. BulletFlight's G7 data is courtesy of Bryan Litz and I recommend his book: http://www.appliedballisticsllc.com/index_files/Book.htm
Up to five ballistic coefficients with corresponding velocity thresholds may be used for each profile to enhance accuracy, or use a single G1, G7, or G8 value.
Several built-in profiles for the Army's M110 and M110C semi-automatic precision rifle, the Army's new XM2010 sniper rifle, the 14.5 inch SR16 rifle, The 50 BMG M107, .308 M40A3, .308 M24, and the 6.5mm KAC PDW allow you to get started quickly. You may alter these profiles, or add new ones.
This app is currently in combat use by military snipers in Iraq and Afghanistan.
Built-in profiles for common military rifles, but easily add more custom profiles.
Accurate bullet database with most major brands.
Works with Kestrel BlueTooth weather meters.
3000 meters range (2000 using simple screen).
Fast and accurate ballistic computation using G1, G7, or G8 ballistic coefficients.
Easy to use interface yet powerful and full featured. All relevant data on screen all at once.
User interface designed to minimize chance of input errors.
"Simple Screen" with distance wheel, but also "Full" screen where any exact range may be used.
Output in inches, cm, MOA, Mils, and scope clicks.
Option for Metric units. In most cases imperial and metric are visible at the same time.
Direct input for scopes with either MOA or mRad metric input (such as Schmidt & Bender).
Calculates 360 degree wind drift using either degree of O'Clock format input.
Wind speed may be specified in either miles-per-hour or meters-per-second.
Advanced atmospheric model.
Uses GPS to locate nearest weather station and then automatically gets weather data and altitude for ballistic computation.
Sight-in weather may be logged and stored for automatic normalization to standard conditions. So you may sight in at any temperature or altitude and later be accurate at any other temperature or altitude.
Built-in accelerometer will detect angle for improved accuracy.
Computes actual BCs from collected data. Some users will do this for each log of ammo before a mission.
Built-in mil-dot range calculator.
Calculates bullet twist / stability with a highly-accurate formula.
Computes bullet spin drift.
Built-in help screen.

The best way of measuring an air guns power output without a an actual chronoscope!
Chrono Connect Mobile Lite will monitor the speed of pellets leaving your air gun, rifle, pistol and display the speed and power for you in your chosen speed and power units.
Lite version requires you to enter all pellet and distance details manually and will measure the speed of 3 shots at a time. Prove to yourself it works before going Pro!
Pro version includes many advanced features not in this Lite version including.
- Unlimited shots in one go ( no 3 shot 'Lite' limit ).
- Full list of shots in the string.
- Graph of shots in the string.
- Full shot and string management.
- Comprehensive pellet database ( no need to manually enter weights and BC values for most pellets )
- Comprehensive rifle and pistol database.
- Visual over power warnings.
Chrono Connect Mobile works by reading your gun firing a pellet over a known distance so all distances should be entered as accurately as possible to ensure accurate readings.
When set up and used properly, Chrono Connect Mobile can be within a few feet per second of a real chronoscope device.
This app was created because I have heard of people doing the following things to determine the power of their airguns when they don't have a chronograph.
- Shoot into a yellow pages and count how many pages were shot through.
- Shoot at the ground and measure the 'mushroom' of the pellet.
- Shoot a coffee can. Did it go through 1 or 2 sides?
- Shoot a soda can in various places, if it goes through X place its X power.
Chrono Connect Mobile is a far better way than any of these methods of determining the speed and power of your gun.
As there are variables that are beyond our control you should not rely on Chrono Connect Mobile as your sole method of recording speed and power and should test the power of your gun using a real chronoscope if in any doubt.
For newer devices use 'Range Card Pro'
