Ratings and reviews

Perfect app for what it's designed for. There is a learning curve but once you get used to where everything is, it flows easily. As you go to the range and find you need trajectory validation due to hot/cold powder, you can. Play with it at home and get used to the interface, then at the range it's almost faster than looking at your dope card through all fields finding the right range. GREAT APP!

Works great! Probably one of the best ballistic apps out there, and totally worth the money. Would love to see an introductory tutorial though: something that walks a new user through the process of inputting your firearm, ammunition, and optic, validating your dope, inputting other variables like weather, and other functions of the app like the calculators. I would also love to see a laptop version, for at-home use or for those who like to being their computers with them to the range. Would totally be willing to pay for the software.

Have been using your app for several years in competition. I rely on it heavily and it does not disappoint!! I have found if the inputs are correct, then the outputs are spot on. I also use the truing function to adjust the ballistic curve. I do have a request .... In shooting competition I often dial in a new zero and then hold for different ranges depending upon how the stage is laid out. Would it be possible to add a "temporary" zero adjustment for each location in the multi target function. That would allow me to set a new zero and have the holds update accordingly. It should only impact the holds for that given location. Much like you can do in the reticle view when you adjust the turret. It would also be helpful to dial the turret or set a field to negative values the way I can on my physical turret. Thanks for an awesome product. BTW I respectfully disagree with the previous reviewer, I find the interface to be easy and intuitive compared to other apps on the market.
