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. FEATURES • 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 HEADS-UP DISPLAY 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. REFINED ACCURACY 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 ## Key features - Real-time sensor integration - Heads-up display (HUD) - Moving target tracking - Unlimited equipment profiles - Cloud backup/sync - Long-range accuracy up to 5000 yards - Scope turret calibration ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Full TRASOL Upgrade | $39.99 | one-time | ## Recent user reviews (10 of 42) All indexed reviews: https://appshunter.io/ios/app/trasol/id1015112834/reviews.md ### 5/5 — Still my favorite. *2023-09-27* Easiest most useful interface. Very accurate! ### 3/5 — Trial version doesn’t do anything. *2023-08-02* Downloaded a few yrs ago. Unused, deleted it. Downloaded again. Now all it does is prompt to upgrade. Can’t view any other screens ### 1/5 — Deleted it *2023-01-12, version 2.2.0* Decided to give this app another shot as I download it years ago. Redownloaded and was immediately forced to pay $39.99 to upgrade to able to continue using it. Deleted app. ### 1/5 — Free version expires? *2022-06-24* The free version has begun opening a pop up trying to force me to upgrade. There is no way to close the pop up. No where does it state that the free version expires after so long. I will not be upgrading and I will be deleting this “free version” from my device. ### 4/5 — Awesome app, just needs powder temp! *2021-10-07* Love this ballistics calculator. I’ve used Shooter (still my fav), Applied Ballistics, and TRASOL. Using it more and more and love how quick it is to operate. One note to developers, please add powder temp capabilities! ### 4/5 — Elevation off maps is off. *2020-06-18* . Just downloaded the app, sitting in Gonzales Louisiana and hot the button to auto fill elevation and it input 2022’. And I know for a fact even on the 3rd floor I am only about 40’ above sea level. Sure it works perfectly if I manually input elevation. Looking forward to stress testing this next week in Wyoming when I get home Thanks James ### 1/5 — Inaccurate data *2019-05-04* Input my ballistics data, my dope is 2.73 MOA @ 195 yards but only 1.81 MOA @ 200 yards! Something is wrong with this program! **Developer response:** Hey there, your feedback helped us discover a small bug in the app. We've fixed this issue in the latest release, and would love for you to try it out and let us know! ### 1/5 — Doesn’t work for me *2019-01-09, version 2.0.1* Haven’t been able to use the product yet as the pressure (Inhg) does not go below 25.00. Living above 6500 ft this creates a problem. Further if I attempt to get the environmental information from the capture button the app crashes. Pretty poor performance after spending the money on the app. ### 3/5 — Not work in Europe *2019-01-07* I am disapoint because i pay 25$ and Trasol is not suport in Europe! Problem is at end after add all parameters u cant count results. ### 4/5 — Good interface, two requests *2018-11-04* 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. ## Frequently asked questions about TRASOL ### What does TRASOL do?
