            Love this App!. Works great! Please include reticle for the new Discovery scope!
            Nice very nice !. This is really a sweet little ballistic calculator I'm glad I purchased it. And there constantly updating it which is what we all
            want for the different scopes we have !Thank you!
            Perfect shot. I didn't see any reviews for this so I thought I'd write one. I have several ballistics apps but this is the one I always go to in
            the field. I hunt in areas where long range shots are required and th
            Awesome!. I am relatively new to longer distance shooting. I used this app today with my new .223. After sighting in I was able to hit a
            milk jug at 450 yds first try. One thing I would like to see added is the
            Excellent!. Allows easy saving of both rifle and ammunition load data. Makes corrections based on observed performance easy. Prevents
            duplication of effort.
            J-dog. Works amazingly well! Would like to see a vortex viper 6.5-2ox5o with a mil dot reticle please!
            Great app!. I love this app but I read in Guns & Ammo that one could enter barrel length & rifle make/model. I'm not finding where to input
            this data though.
            New Feature. iStrelok is still my go to app for target shooting and calculations. The new feature to use the camera to measure slope is very
            cool. It seems close enough to accurate to me. Better then my eye ballin
            IStrelok, Very Impressive. I read a review in G&A, written by Tom Beckstrand. So I thought "Hmmmmm, I ought to check this out. I downloaded on my iPhone &
            was wishing I had an iPad. The iPhone works well but U have more screens
            Good app. This app is very accurate! I used it to hit a 10"x12" steel plate at 500 yrds. Need to add humidity to the settings.
            Ballistic app. I love this app I find it to very helpful and really close to correct
            Perfect app, great price and features. You get a lot for your money with this app; calculations based on weather, ammunition and distance and so much more. The reticle
            library is amazing and helps picture your shot before you even look thr
            Works great. Used it out to 1k and hit on second shot.
            Awesome. This app has evolved into an essential tool when precision shooting. It has majority of needed features of far more expensive
            ballistics apps but without the extra fuss or charge. It has the ability t
            Excellent. Love this app very accurate best ballistic calculator ever
            Glitch. Start off by saying great APP. I have found a glitch in the program. With a 25-06 reduced load 100 grain bullet 2550 muzzle
            velocity. I started to sight in at 25 yards and at 100 yards the program was
            Very Nice!. Very Accurate and the support from the author is amazing, you need a reticle, he will get it for you. A
            Best app available. Works great, tons of reticles, loads of features/settings/adjustments and ACCURATE!
            Strelocker. Bought Strelok Pro and did not like it nearly as much as straight up Strelok. The reticle feature is better for a kinestetic
            learner. Values on chart is fine, but calculate then show in reticle is fan
            Works well. Dead on every time no problems ! Keep up the great work!
            Awesome app. Easy app to navigate around in. Shot out to 1000yds on my first shot! Hit it several times.
            Physical Placement. My elevation was mismatched compared w/Bullet Flight program,soI got physical printing at 400 and 600 yards and tweaked my temp
            sensitivity to 1.0 till it matched my dialed hits Strelok matched my act
            It works.. There is nothing I can say about this program other than if your data is good this solves the equation correctly every time.
            1,000 yd shooter. AWSOME app! Very accurate on its calculations. Very frequently updated and new reticles and features being added.
            Great app. Awesome app, very reliable, and easy to use. Also, Boris could you look into adding trijicon accu point reticles please.
            Thanks
            iStrelok. Boris great program. Would you please add the Konuspro-275 reticle for 3-9x40Thank you for your time and cooperation.Sincerely,Dan
            Edwards
            Great. I love this app. It provides a great tool for all types of shooting. If you want to get the most out of your equipment this
            app is for you. Accurate and easy to use. I use it to set up reference
            O. Works amazingly well! Would like to see a basic cross hair hold over for Leupold, Nikon, and weaver scopes!
            Review. Please include ziess reticle 20 ( duplex) reticles App works very well took deer at 267 yrds with muzzle loader using ballistics
            from app seems to be accurate
            I love it. I have used it many times easy to set up as well. One day at the range the guys gun next to me went down and some one gave him a
            loaner we guessed on on a few of the items using what we knew about the
            Доволен. Приложение очень понравилось, стоит своих денег.
            625 yard kill!. During a Nov. 2012 whitetail hunt made a 625 yd shot using iStrelock to calculate the ballistics. Dead on!
            Отличная программа. Очень удобная программа, избавляет от нужды таскать с собой записи с
            баллистическими расчетами.Есть практич
            Worth the 5. Really like it. This is really great for a normal shooter. The ability to get info in clicks or in reticle holdover is great. Some reviews say
            this is a free app but I paid 5. Totally worth it. There is a pro vers
            Very accurate!. Thank you for adding the zoom feature! This makes a tremendous difference with the scope you are using. As long as you know your
            bullet specifications and sight it in properly, the program gets you th
            Thanks for another update!. I love that this app gets constant updates to add new reticles. Any shooter should have this on all their iOS devices.
            Bev 4. Just loved the thing works way better than I thought it would!
            Trijicon. TA31F. Is it possible to add the Trijicon TA31F ?
            Add something please. Great App! Works great. I could greatly use the Bushnell 3200 elite tactical scope though! Thanks for making this app!
            Excellent App!. One of the best apps I have. By far the best shooting/ballistic app I have. Anyone would be a fool to spend on a ballistic app as
            long as this one is available. I have used this to shoot to 600 yds w
            Works like it should. Very useful and works well. Definitely worth the price. Would have been perfect if it had the Primary Arms 3X compact scope so it
            could be used for all my rifles.
            Fantastic!. Author is very responsive and updates regularly with improvements and user suggestions. Program works as advertised and allows
            shooting site and weapon variables. Well done!
            Thank you for the quick response.. Love the app. Thank you for adding the Nikon Coyote special 4.5-14x40 BDC.
            Very accurate. Dont know why this has only 3 stars? I guess some people are idiots. Spend a few minutes learning how to use. Amazing- no carrying
            around little notes about different loads and bullet drops. Also has
            Best app for field shooter. Excellent app, especially reticle function, makes it so easy to just hold and shoot. Also makes a good guide for reticle shopping.
            Mr. Mr.. I love the interface, but I also shoot a lot of factory ammo that already supply the ballistics specific to the bullet type, load,
            velocity and other data. What this APP need is the ability to add / t
            Natural - 6%
            Nikon M-223 scope is not on here. This is a really cool app, however the Nikon M-223 4x16 NikoPlex is not on there.Please add it, thanks!
            G1 vs G7 drag factor. Great app although it only calculates your drop based upon a G1 drag factor when the majority of bullets should actually be
            calculated using G7. You wouldn't think that it would equate to much correct
            App crashes when changing reticle to NightForce NP. Please fix. This app looks promising
            Reticle. I really wish they would add the Nikon mil dot to the arsenal of reticle displays and charts. I have three scopes with this
            reticle and only two with bdc reticles
            Reticles. Need more reticles, to include those on current issue military weapons. For example the Trijicon ACOG and EOTech red dot Family of
            scopes.
