Stop adjusting – Start hitting.
Utilize the most effective ballistic app ever invented. Simple, intuitive and now integrated with smart sensors. With a tap of the icon you can calibrate density altitude, Coriolis, cant and slope in real-time. Fully integrated with our new heads-up-display it enables you to capture video, snapshots and moving target speed tracker.

Get the complicated data out of the way and just shoot. This app will provide you with accurate information as far as you can shoot. Capable of predictable impacts beyond 1500 meters.

New features:
A) Heads-Up Display
B) Smart sensor data
• Stability & spin drift calculation
• Coriolis (Automatic)
• Density Altitude calculation
• Cant (Automatic)
C) Moving target speed tracking
D) Photo/video capturing with image zoom

HEADS-UP Display – View your target and all of your ballistic data in one screen. Use simple icon tools to set range and wind, let the onboard sensors calculate the rest of your ballistic information. Allows you to track moving target speed directly on the interface. You can also record video or photo of your shots to share. By using your mobile device’s built-in camera and onboard sensors, TRASOL allows users to point their device at their target and automatically generate absolute accuracy solutions. 

REFINED ACCURACY – Using our proprietary algorithms; TRASOL is the most accurate ballistic calculator on the planet. No more need to alter manufacturers bullet data to get your hits. We developed new algorithms according to Doppler radar data to create the most predictive flight path possible.
INTUITIVE INTERFACE – TRASOL was built with precision and speed in mind, in order to accomplish this, it had to be simple and un-cluttered. You will find it is very easy to use and intuitive; eliminating unnecessary steps.
• Single screen ballistics entry point. This allows shooters to easily input and verify all variables to ensure an accurate shot.

You want the benefit of advanced accuracy tools, and TRASOL automatically activates these tools as needed to simplify actions by the user. These tools can be activated or deactivated:
• Automatic stability & spin drift calculation
• Coriolis
• Automatic Density Altitude calc.
• Multi-wind Bands
• Cant
• Tracking of cold bore
• Tracking of zero settings
In live-fire testing of TRASOL’s predations the following results were documented:
(.338LM ammunition and strictly using manufactured published data)

Within 0.1 MRAD up to 1400 yards
Within 0.5 meters up to 1700 yards
Within 1.1 meters at 2200 yards

Awesome Solver, When It Works...


This app used to be awesome. Now it no longer seems to work on iPhones. They can’t seem to keep up with iOS updates and the app is unusable due to crashes when trying to use certain functions. And you can’t save your app settings. Keeps resetting to the defaults every time you open the app. I’ve kept an old iPhone that no longer has service just for the app since it will never see an update.

Dead on!

John P Young

After zeroing my .308 at 100 yards I was able to hit targets dead on at 600 and 900 yards easy.

Update: After updating I had to reinstall the app to get it to work. I contacted support and they apologized and assured me it was due to the current syncing feature. They also said that they were working on making it a lot better.

nice app, use it for everything except grouping on the targets.



Update 8/20: the app continually crashed on my iPhone 6s. But worked fine on my iPad. Deleted and reinstalled on the 6s logged into retrieve my data but nothing there, synced my iPad....well it won't sync. Apps works great till this point.

Only thing I would add is the ability to import data from a Kestrel. For that reason I use Ballistic AE and StrelokPro more.
