Why isn't SightSet free?

OK. It's one that we hear a lot - so let's get this one out of the way first. There are lots of free apps out there. Some of them are really good. But the only way that a free app can make money is either from advertising or through in-app purchases. For advertising to work, it has to have millions of users who use it constantly. All day. Every day. (For SightSet, as good as we think it is, that sort of usage just isn't going to happen.)

On the other hand, apps that use the in-app purchasing model often either rely on people making impulse buys and not keeping track of what they have spent, or offer something of limited functionality until you pay for the upgrades.

We would much rather give you a fair-priced, fully-featured app. One where you know exactly how much you'll pay and exactly what you'll get for your money ...So although it might cost a bit more than you were expecting, for many calibers of commercial ammunition, SightSet can pay for itself by saving you as few as 10 rounds of ammunition when sighting-in.

Who is SightSet for?

Well, pretty much anyone who uses rifles, air rifles, pistols or air pistols with adjustable sights (either telescopic, diopter or straight mechanical) and wants to get the most out of their kit by shooting as accurately as they can. We've now got users in more than 58 countries, on every continent in the world (...except, maybe, Antarctica - but then penguins aren't big shooters anyway).

For sports shooters, SightSet is a great aid for sighting in your rifle scope before you go out into the field.

What does SightSet give me that a Ballistics Calculator doesn't?

For shooters on indoor ranges or short distance outdoor shoots, a ballistics calculator is probably unnecessary.

For long range outdoor shoots, a ballistics calculator is great for giving you the best chance of getting a first round hit on target, but only after you've sighted your rifle in! (And you might need to do that often if you're swapping sights or changing ammunition loads.)

Since ballistics calculators use theoretical data, they still rely on you accurately estimating parameters such as wind speed, direction & air temperatures, as well as having known & consistent ammunition characteristics.

So here's how SightSet complements a ballistics calculator:

  1. It's a great help to do the initial sighting-in - at any range that suits you
  2. When you're shooting for real, a ballistics calculator is going to allow you to compensate for bullet drop & atmospherics to get you onto the target...

...but it just isn't going to give you the precision to hit bulls. Once you've hit the target, you still need something that's going to help with that last little bit of sight adjustment (and maybe a lot to correct for wind-drift). That's where SightSet can help: it will calculate the necessary corrections based on what you actually observe, not what you estimate.

Are there any differences in capability of SightSet on iOS & Android?

It's certainly not our intention for there to be! Inevitably, since we haven't developed the two version is parallel, there are some differences. At the moment, the iOS version offers a couple of features that the Android version doesn't (yet):

What sight definitions does SightSet include?

To get you started, we've included standard definitions for 1/4" at 100 yards, 1/2" at 100 yards, 1/4 MOA, 1/2 MOA, 0.5cm at 100m & 1.0cm at 100m... but it's really easy to add your own.

None of the definitions covers my sight, what do I do?

You can easily create your own (see Core Tutorial 4 on the videos page), but please make sure that we cover the click setting that you need. (If we don't, then please contact us. With the new dynamic database update facility, it's a lot easier for us to add something.)

What click settings are supported?

We include 33 click settings...

US/Imperial (all at 100 yards): 1/2", 0.36", 1/3", 1/4", 1/5", 1/8", 1/10", 1/16"

MOA: 1, 2/3, 1/2, 1/3, 1/4, 1/5 1/6, 1/8, 1/10, 1/16

Metric (all at 100m): 3.5cm, 2.8cm, 2.0cm, 1.5cm, 1.25cm, 1cm, 0.7cm, 0.64cm, 0.6cm, 0.5cm, 0.4cm, 0.35cm, 0.32cm, 0.25cm, 0.2cm

That pretty much covers the adjustments that most people are likely to come across.

Even if we don't include your sight, there are still a couple of possibilities:

  1. If you have a sight that is specified at 50 yards rather than 100, you might be able to just double up to find an adjustment that's already there. So, a sight with an adjustment of 1/4" @ 50yds is equivalent to 1/2" @ 100yds, for example.
  2. Even if there isn't an exact match, one of the predefined settings might be really close. You can check in the PDF file list for small bore, pistol, air-rifle & air-pistol sights.

SightSet also allows you to configure different settings for windage & elevation adjustment, or omit either one if your sights aren't adjustable in that direction.

...What about MIL sights?

Not directly supported at the moment, but since 0.1mil (NATO) is equivalent to 0.9817477074cm at 100m, for most people it's good enough to use the 1.0cm click setting (or 0.5cm for a 0.05mil sight).

The click setting for my sights isn't supported, what can I do?

Let us know! With our dynamic database update facility, it's easy for us to add any popular settings that we may have missed.

Where can I buy the Xiscan/Apphelia Targets?


We seem to have created a bit of a problem for ourselves, so let's address it first.

First of all, we don't produce paper versions of any of the targets in the app ourselves. Nor do we suggest that you use any one target in preference to others in the app.

So if we don't supply or endorse Xiscan/Apphelia targets, why are they there, you may ask? Well, we do try our best to include popular targets that our users have requested. However, we haven't always been able to get explicit permission from a target supplier to use their name in our app. Consequently, at the request of our customers, we have produced a small number of targets to the same dimensions, but kept them "anonymous." (So if you already know and use the targets in question, you're good to go! ...otherwise, we're sorry for any confusion.)

What targets are included?

We include over 140 target definitions. These cover the commonest rifle, air rifle, pistol & air-pistol targets from NRA (45: A-, B-, C-, AR-, LR-, MR-, SR-), ISSF (6) & USA Shooting (8).

There's also great news for our British, Australian, Canadian, German and International users, with the inclusion of:

Why don't you include targets from <XYZ...>?

Unfortunately, not all manufacturers or shooting bodies publish their target specifications. However, if you can point us in the direction of any common specifications that we are missing, please get in touch through the Support page. With our new dynamic database update facilty, we're keen to add new targets as often as we can!

The targets I use aren't included, what can I do?

SightSet includes a basic target editor for creating roundel-type (or square concentric) targets. You enter the target dimensions, ring sizes, etc. (using US/imperial or metric measurements) and SightSet will save the details so you can use them again and again. (But please make sure that SightSet does what you want before you buy by watching Core Tutorial 3 on the videos page.)
