Stop adjusting – start hitting.

Utilize the most effective ballistic software ever invented. Simple, intuitive and now integrated with smart sensors. With the tap of a button you can calibrate density altitude, Coriolis, cant and slope in real-time. Fully integrated with our new heads-up display, TRASOL enables you to capture video and snapshots, as well as track moving targets.

TRASOL was developed for precision shooters who desire first round hit accuracy out to 5000 yards.

• Interfacing HUD
• Automatic device sensor input
• Unlimited equipment profiles
• Cloud backup/sync for equipment data
• Range up to 5000 yards (4572 meters)
• Highly accurate trajectory prediction
• Moving target speed tracking
• Scope turret calibration
• Cold bore adjustment
• Light/dark color themes
• Built-in tutorials
• Free trial

There is genius in simplicity. TRASOL is the first ballistic application to incorporate Heads-Up Display technology. By using your iPhone’s or iPad’s built-in camera and onboard sensors, TRASOL allows users to point their device at their target and automatically generate absolute accuracy solutions.

The HUD environment has highly intuitive drag-and-drop tools for quick input of range and wind, and the device’s sensors do the rest. The HUD also allows tracking of moving targets to provide very accurate lead solutions. Photo/video capturing capability allows you to log your shots easily and share them with your friends.

Utilizing proprietary algorithms, TRASOL is the most accurate ballistics calculator on the planet. No more need to alter manufacturer bullet data to get your hits; we developed new algorithms using Doppler radar data to create the most predictive flight path possible.

In live-fire testing of TRASOL’s predictions the following results were documented (.338LM ammunition, using manufacturer's 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

Purchase restore was broken, now fixed and a great app

*Updated* v2.0.1 fixed the issue below. I like the clean, straight forward layout. I definitely recommend Trasol to be in your precision shooting app folder.

The new update looks nice. However, it claims I don’t need to purchase again if I previously paid for the full version. Attempts to restore the previous purchase fail, and the trial version is not feature-rich enough to be worth the effort. If they fix the purchase restore I’ll be happy to attempt to use this app.

Developer Response ,

Hi kevwil, there was an issue with our “Restore” option keeping some people from upgrading old purchases. The issue has been fixed now - we’d love for you to install the new update and report back!

Good interface, two requests

I like this app’s user interface. The most important improvement for me would be the ability to print the ballistics table. In addition, it would be helpful to add the effect of powder temperature on muzzle velocity. With those two changes I would give it 5 stars.

Best ballistic calculator

The new update is amazing. All the issues I used to have with the app have been fixed - you can tell a lot of thought was put into the new design. Accurate solutions for all my rifles. Easily the best ballistic app out there.
