Absolutely brilliant app for working out your Scope settings. Takes a moment to understand what everything means, but if you are in to Air, buy yourself a Chrony and Range Finder and take the guess work out of your trajectory. What would make it even more amazing is more customisable options, so instead of choosing metric or imperial, be able to change individual parameters. To be able to switch from moa to mrad would be very useful. To show Line of Sight on a graph would be fantastic 👍

I've been using it for years. It gets better slowly. It still crashes upon reopening often. But it's easy to use and operate. I would love options to print intercept charts, or an offer of an ideal zero.

A great app works well on my s7 edge only gripe is I can't see where my hold under should be at certain ranges as the little pink dot has now disappeared and there are no reference points above zero. I use it to memorize my hold under/over when at different mag so it makes for quicker decisions when out shooting (please sort it 😊)

I have used Chairgun since before Hawke got it and made it better and better. I have tested every online and moble app and Chairgun is the most versatile and usable, even if it does not contain every bell and whistle. Sorry to see it shut down, please give it to someone else to keep it alive.

This is my favorite airgun ballistic program ever. And having it on my phone means I have access to it anywhere. If you shoot airguns you need to get this. If you don't have a chronograph just look online for your airgun review and many will test different pellets and tell you what the velocity are for different ammo.

Tons of information and calculations! This is an excellent tool to use if you're a serious shooter. Not necessary for plinking.

This app is excellent it works best with a Hawk scope but also work with a generic mil setting and mil dot scope, you need to practice using it to understand it, also you need a chronograph so you know feet or meters per second.

Overly complicated with no tutorial. The slider for the range on the reticule does not show up on my S8 so I can't see where to aim at close targets.

UI looks like old dogs**t. App doesn't save doesn't load up your saved user file on start

Mic. T. Apr 3, 2022     

Calculations are way off, 759 fps 10.1 ft/lb at muzzel showing 2.8 ft/lbs at 25 yards ☚ī¸ it's actually measured at 6 ft/lbs with the pellet, can't trust any calcs.

Very good app. Easy to set up, controls are friendly, has lots of pellet info. I recommend it to any airgunner.

Just totally confusing, the Windows version is very easy to use and understand. This is not user friendly.

Ali. A. Oct 6, 2018     

A great help when aiming at long ranges, one of the most useful apps out there.

Joh. T. Mar 13, 2020     

Extremely useful. Saves so much work. It would be even better is not limited only to Hawke scopes.

Ian. D. Oct 31, 2020     

The old version was clunky but it worked well. I always rate hawke products high as I have never been let down by them yet.

Phi. P. Apr 7, 2021     

Used to use the old PC version of ChairGun, and coming back to shooting, the app is great.

Wish it was still supported/ updated best app out there even tho not supported any more A*****

mar. B. Apr 6, 2020     

Best application ever rich with graphs and tables with many pellets types and their relevant drag values.

Joe. S. Jun 3, 2020     

The pellet database needs updating with QYS (QIANG YUAN SPORTS) these pellets out do many pellets in your database. And I think lots of people will eventually change to them once they build up reputation

Ben. G. Feb 23, 2020     

Good day. Will you please update the ammo on the app. Specifically put in the new H&N HP slugs. This will really be a great help.

tur. b. Feb 14, 2022     

Needs some support and an update to the database

Pri. A. Feb 3, 2020

Jam. L. Oct 19, 2021
