[H2] Reviews
EAGLE BALLISTICS app review.
I've been using this app all winter alongside a Kestrel 5700 Elite AB. Shooting has been from around 500 yards to a mile. Ranging is with a Leica 3500.com and wind speed from the Kestrel. I'm not sponsored or employed by Barbourcreek or anyone else, just a long range enthusiast. I have a mile range to shoot on and the rifles used for testing are all custom rifles built by West Elk Precision. The two mentioned here generally shoot in the .3's. All have Schmidt Bender, March, or NF ATACR scopes. The most used is a 300 Norma Improved shooting 245 grain Berger EOL's at 3036 fps. The Kestrel has been very accurate but there were times when the solutions just weren't right. I used the custom drag models for BC's but again got too many solutions that were off so stuck with G7 BC's. A couple of specific examples summarize what I found. Shooting prairie dogs in Utah I ranged one at 1167 yards. Using data from the Kestrel I hit several shots a little high and left. Switching to data from EB I hit the target. The following day I had one ranged at 1121 yards. Using the EB data resulted in a first shot kill. Shooting at a mile there were frequently small but significant differences between the AB and EB solutions. Another frequently tested gun is a PRS rifle in 6BRA with an S&B mil scope. Again the two platforms were often identical or close enough not to matter, but at longer ranges, out to 1300 yards, there were sometimes up to .2 differences in their solutions. The EB app became the one I trusted as it was consistently correct. I also find the EB app to be more intuitive and easier to navigate. I never have to recalibrate the compass and making changes to existing data or entering new guns and data is quick and easy. There are a number of features to calculate and correct BC, to correct velocity if need be, to quickly set the distance between center of scope and bore, and a few other features I have yet to dig into. There are also several well executed YouTube videos accessible on the EB website that explain the app and how to access different features. The bottom line is the Eagle Ballistics app has gained my trust and when the Tract Toric rangefinding binoculars with the EB engine becomes available in March they will replace my Kestrel and Leica.  Nothing like it anywhere in the world !  I have been using applied ballistics for years. This app has given me more accurate numbers . I have been on target on first shots way more on kills ant target shooting past 1000 yards. Amazing app I don’t use anything else From the truck to the bench and on steel at a 1000. Very user friendly and intuitive app. Sync’d to Vortex 5000 and Kestrel elite with zero issues. m.

[H1] Muzzle Velocity and Ballistic Coefficient Truing Tool
This tool is used for truing the values for your Muzzle Velocity or Ballistic coefficient. The process for truing both of these is similar and both will be covered here.Should I true the Muzzle Velocity or Ballistic Coefficient? Our recommendation depends on whether you have an accurate Chronograph available. If you do not have a Chronograph, we recommend truing the Muzzle Velocity. If you do have a Chronograph, we recommend first measuring the Muzzle Velocity using the Chronograph and then truing the Ballistic Coefficient using this tool.
[H2] Instructions
Be sure to true scope correction before truing muzzle velocity or ballistic coefficient.
Enter all parameters for your firearm and confirm your normal zero
Select a Range based on this tool's recommendation. The recommended range is around 15% before the range at which the bullet is 1.2 times the speed of sound.
Fire on target and adjust turret until on target.
Enter turret value into Required Dial Up field.
Choose to true either Muzzle Velocity or Ballistic Coefficient.
Review calculated trued value.
If Error is shown, then the difference required to true the firearm was too large. You may have entered an incorrect value or need to start with more accurate values first.
If Unchanged is shown, then the firearm is already trued. Nothing further needs to be done.
If a value is shown, this is the value calculated for the Ballistic Coefficient or Muzzle Velocity which would result in impact at the given range. If trued value is acceptable, press Set to switch to that value.

Sensitivity Tool Video Link
[H1] Sensitivity Tool
This shows an analysis of how sensitive point of impact is to parameters. The purpose is to provide a sense of the relative importance of different parameters.These analyses are calculated by solving for the amount of change required in one parameter to cause impact to change by a given amount. In the analysis, all other parameters are left unchanged. The distance solved for in the analysis is 1in for Imperial and 2.5cm for metric).It is important to understand that sensitivity may be dependent on the other parameters. For instance, different parameters have different importance at different ranges. Latitude affects the significance of Azimuth and its impact on earth-based effects.The same analysis is made for both positive and negative variation; sometimes these can differ substantially.In some cases, a variable may not have any (or only a very small) effect on the point of impact. These may be reported as NA in the table.Range Card Video
[H1] Range Card
This tab is used to generate range cards and other data based on your configuration.For any of the cards, you may choose to email or print the card using the buttons in the toolbar.
[H2] Range
This card shows standard ballistic data for varying ranges.
Range: distance corresponding to this row of the card
Path: how are the bullet is below the scope reticle at this range. This distance is given both in a linear distance (inch/cm) and scope angle (MOA/mil).
Drift: how are the bullet has drifted left or right. This is given in both linear distance (inch/cm) and scope angle (MOA/mil).
Velocity: projectile velocity at this range.
Energy: energy of the projectile at this range.
TOF (Time-of-Flight): time since bullet has left muzzle.
[H2] Wind
This card shows ballistic data for varying winds. This card can be useful to quickly make wind holds based on changes in wind speed and direction.
Wind Speed: wind speed in MPH or km/h.
Elevation: Scope setting for this wind. This may have small changes with wind caused by Aerodynamic Jump.
Wind Hold: The hold required for this wind.
[H2] Detailed
This card provides details about current firing configuration.
[H2] Label
Create a small table of dial up and wind holds. This is intended to be printed and taped to your rifle stock as a quick reference to be used at shorter ranges if a more complete solution is not available. Ranges are only included out to 500yd (500m and wind speeds up to 5 MPH (metric: 10 km/h). The ballistic solutions are calculated for zero inclination, no earth effects (Coriolis or Eötvös), and no target movement.Hud Video
[H1] HUD Settings
These settings control operation of the Heads Up Display (HUD). They are available in the Settings, but are provided here for quick access.
Using Tripod: When enabled, this indicates you are shooting from a tripod. Use of a tripod can allow a certain amount of barrel rise, requiring an adjustment in order to impact target. When enabled, a warning is shown in the HUD so you remember to turn it off.
Target Mode: This allows selecting between Single and Multi. Single Target Mode is used for individual targets. Multi-Target Mode allows organizing sets of targets which will be shot in groups. When Multi-Target Mode is selected, (1) the HUD no longer shows information about impact and instead shows listings for up to 5 targets in the current group, (2) the current selected target and those after it are shown if they are in the same group, (3) Rain and Mirage selectors are shown in smaller form.
Max Ordinate Units: By default, Max Ordinate is expressed as a scope angle (MOA or mil). This allows the shooter/spotter to know the approximate location in the scope. When this is enabled, the Max Ordinate is shown in distance (feet or meters).
Hold for Aerodynamic Jump (Single): When enabled, vertical holds are split into two components: the portions not affected by wind and the portion that is. The first is summed and rounded to your scope turret units to be dialed in. The second is a vertical hold you can make based on changes in the wind. The purpose of this is to make it easier to hold for Aerodynamic Jump. When making these calculations, the full accuracy is retained when determining the hold so that any fraction not used in the turret adjustment is included in the vertical hold. Because of this, there may be a non-zero vertical hold even when no wind is present. Note that this affects both the HUD and the Wind Card on the Range Card.
Relative Wind (Multi): When enabled, the Wind Direction for targets is adjusted according to the relative Azimuth compared to the selected target (which has a highlighted border). This allows the wind direction to be set once for the selected target and have it automatically adjusted for the other targets. This also causes the adjusted relative wind to be shown for each target in the HUD table.
Moving Targets: When enabled, moving targets are supported. This causes the Mover Speed setting within Target section to be shown and additional Mover Speed and Mover Hold fields to be shown in the HUD. Holds for moving targets are not incorporated into the holds; only an incremental hold is shown, which must be added/subtracted to the wind hold according to direction of movement. If not in use, you may wish to turn this off to reduce clutter on the HUD.
Show Temperature & Pressure: When enabled, Temperature and Pressure are shown in the HUD. You may wish to disable this to reduce clutter.
Prefer MOA Fractions: When enabled, fractions (e.g., ¼) will used in the HUD in place of decimal values. This may be helpful in making turret adjustments. This setting only affects MOA-based turrets (not mil). Fractions will also be used in other situations, when appropriate.
Inclination & Azimuth Tool: When enabled, the internal accelerometer sensor in your device will be used in the Inclination & Azimuth Tool to determine your angle of inclination.
Moving Targets
[H1] Video
[H1] Mover Speed Tool
This tool estimates the speed of a moving target using range, your scope reticle, and a timer.Use of this tool requires a rifle or spotting scope with an appropriate reticle. The reticle must have measurements. Please be sure to refer to your rifle scope manual to ensure you know how to correctly read measurements with your reticle. See Rifle Scope section below for more information.This assumes you know the Range to the target. If you do not know the range, you can use the Ranging Tool to estimate this.After the range has been determined, there are two methods to using this tool: Known Distance Method and Known Time Method. In each method, you will first set the Movement Distance or Movement Time and the use your scope reticle and a Timer or Stop Watch to determine the other parameter. The steps for each method are provided below.
[H2] Settings
These are the settings and controls used to operate the tool.
Range: The range to the target. This is used with the Reticle value to determine the distance the target moves. Changing this value affects other parts of this app.
Reticle: The observed angle measured by your scope reticle for the amount of distance the target moves. Changing this value causes the Movement Distance to be updated.
Movement Distance: The observed amount of motion of the target. Normally, the Reticle is used and this value is only read for confirmation. However, in some cases it may be easier to estimate distance of movement, such as if there are large objects in the field of view of know size. Changing this value causes the Reticle measurement to be updated.
Time: Amount of time the target moved across the given distance. You can enter a value here or use the Stop Watch to measure a time.
Mover Speed: This is the calculated speed of the target.
Set Mover Speed: Press Set to change the mover speed to the calculated speed and close this tool.
Timer / Stop Watch Selection: This selects the mode of the time button either as a Stop Watch or Timer.
Timer Button: This button operates a Timer or Stop Watch depending on the mode selected. The button is intended to be operated while looking in your rifle scope so it is very large and vibrates. For improved accuracy, the button is triggered when you touch it (most IOS buttons are triggered when you lift up).
In Timer mode, the button is pressed once to start a timer based on the current Time value. The timer counts down the time and it alerts when expired. It vibrates once when started. It vibrates twice and flashes the screen when it expires. This mode is used with the Known Time Method.In Stop Watch mode, the button is pressed twice: once to start a stop watch and a second time to stop the watch and store the elapsed time in the Time field (and update the estimated Mover Speed). It vibrates once when started and twice when stopping. This mode is used with the Known Movement Distance Method.
[H2] Methods

Observe target in scope.
Press Start button.
Press Stop button when target has moved the expected distance.
Confirm Time and Speed values.
Press the Set button.
[H2] Rifle Scope
It is important to know what focal plane your scope uses. You can determine this by changing the magnification level. If the reticle size changes with magnification level, then the scope uses first focal plane. If the reticle size remains the same, then the scope uses second focal plane.
First Focal Plane: This is the preferred type of scope. First focal plane reticles change size as you adjust your scope magnification. A first focal plane scope reticle can be used at any magnification level.
Second Focal Plane: Care must be used when measuring angles with this type of scope. The reticle stays the same size regardless of magnification. Reticle measurements are only valid at a specific magnification level.This is commonly the highest magnification; sometimes it is a magnification level marked on the numbering with a tick. We recommend using this tool only when a second-focal plane scope is at this magnification level.
For other magnification levels, any reticle measurements must be adjusted appropriately. For instance, if you use 1/2 the magnification level, then the reticle measurements will be double (2x).
