It is unfortunate that there isn’t 10 stars because STRELOK PRO deserves them ! I have been using this calculater for many years ,out to 2 miles, and it has preformed with unbelievable results. I have payed for several other calculators because my friends try to tell me that they are so much better but after reviewing them they where not even in the same ball park with STRELOK PRO. I can tell you that as long as you put your data in this program correctly it will preform unbelievable well. I have been in training courses where I was expected to hit head size targets at varying yardages out to 1000 yards and with the help of STRELOK PRO I came in at the top of my classes. I shoot from 22 center fire to 408 CheyTac with the same awesome results from this program. I am not receiving any thing from Strelok for this post. It is rare to find things that work as well as this program and when we find them we NEED to sing them praise! As for Igor Borisov , the developer , I have emailed him a few times with what I thought was program issues and he responded very quickly to me. So much so that I wonder how he can keep up with it all. By the way the program issues I thought I had was a user issue. I love this program and to prove it I typed this with one finger lol. Thank you Igor Borisov for all you have done with this calculator, without it I couldn’t do what I do!!!

Absolutely Awesome!

As a long time Ballistic AE user I thought dealing with bugs and a clunky GUI were just par for the course with a solid calculator on my mobile device. I’m here to tell you I was so wrong. Strelok is simply awesome, super intuitive to operate, and very well developed. The work and dedication that goes into this app is second to none. Just take a look at the consistency of the development updates and responses. A few things that stand out to me are quick access to G7 data, easy export of reticles, and the ability to save firearms with the scope linked. Overall this is a huge improvement for me over Ballistic AE.

To list a few little things I have noticed.
Sometime when I select a different target it does not always come up In my reticle view. I would love the ability to default the whole app to MRAD but that’s a personal use case. Lastly I do prefer how the Ballistic AE outputs long skinny drop charts that are easy to print and laminate for range use and hunting use. These are such small issues. I give this app a easy 100% hands down!

Developer Response ,

Thank you for the kind words!
I will check my code about targets
On the main screen you can make long tap to dim out unnecessary results digits
You can export trajectory table to xls-file, open it with any spreadsheet editor and print


Best Ballistic App in the Industry

While there are a lot of great apps out there, with StrelokPro you have the ability to fine tune every variable to really true up your trajectory and know exactly what your projectile is doing. With many apps the process to get through the menu’s to update temperature on the fly is time consuming and one thing I love about Strelok is the ability to quickly Bluetooth atmospheric’s in via Kestrel Drop D3 and plot a new solution before the wind changes. There is a bit of a learning curve to understanding all the concepts that go along with long range shooting and Strelok is the easiest and most intuitive app on the market. The developer is very dedicated to offering support and the Strelok community in the Facebook forum is a great resource to learning the ins-and-outs and troubleshooting when you get stumped. If you want to get into long range shooting I cannot recommend StrelokPro enough. Best ballistic mobile app in the industry.

Thanks for the kind words, they motivate me to move on
