The only way to install Artemis is through Google Play.

The upgrades to AdFree/Premium/Coached are lifetime upgrades. Once upgraded you never have to upgrade again, as long as you are using the same Google account. However, sometimes Artemis reverts to Lite (e.g. when you have upgraded you mobile device). In this case, make sure you are online before starting Artemis again. Artemis needs the Google Play app running in the background and able to check online what in-app purchases you own.

Upgrading to AdFree/Premium/Coached always happens in the app itself through Google Play. The available payment methods depend on the country your are in. Check out this Google webpage for the options.

A sight advice is only computed and shown if you;

• Have entered valid values for up/down and left/right adjustments in the sight that your are using for the entry.
• Have entered a valid value in the eye-pin distance (for recurve) or the peep-pin distance (for compound).
• The sight advice is turned on in the options. Note that the advice is given when the 'World Archery rules compliant' checkbox is OFF!

Even if all settings are valid and sight advice is turned on, there is never a sight advice in a match under World Archery rules of type 'competition', because it simply is not allowed.

YES

In fact the BOWDOmeter device is integrated with Artemis.

In the options menu you can turn its use on/off. There are two ways of using it; in live mode it listens to the BOWdometer for bowcanting (not keeping your bow vertical) information and gives live feedback on it. It will also store the bowcant angle for each plotted shot.

If you are not using the live bowcant mode, it still records your Xi values when plotting arrows. The Xi values are displayed in graphs and can be used for analysis.

YES (Polar H7)

In fact the Polar H7 device is integrated with Artemis.

In the options menu you can turn its use on/off. It will not only keep track of heartrate, but more importatntly, it will keep track of your stress level through a very advanced algorithm developed by a team at the Medical Informatics R&D centre at the University of Pannonia in Hungary.

YES

In fact the RyngDyng device is integrated with Artemis.

In the options menu you can turn its use on/off. It will automatically plot arrows on Artemis. Probably the best (and most non-intrusive) way of using Artemis in a high-performance archery program!

NO

At Artemis we are always open to integrate our app with third party hardware. Especially hardware that has something new or interesting to add to archery. To do this, the manufacturer of the hardware needs to either open-up an interface to their hardware so we can integrate ourselves, or we need to agree on a cooperation where we integrate through a dedicated (closed) API. In both cases we need the help/support from the third party hardware manufacturer. In case of Mantix X8, there is no working integration (yet). We can only advice you to contact them with the same question.

Artemis takes a different approach from most other apps. It stores the position of the arrow in a right handed Cartesian coordinate reference system in so-called udevs or unit-deviations. A udev (x,y) is expressed in mm/Pm (millimeters per Park-meter). The unitless 'udev' for the arrow center is used so all arrowcenters can be compared without needing to know the distance shot at and at what kind of target was shot.

The coordinates are in mm/Pm which is very close to mm/m (which means mm per meter distance shot at). The Pm (a Park-meter) is an indication of the distance of the target that takes into account a correction factor such that grouping patterns on different distances CAN actually be compared.

The formula is Parkmeter = 0.815 * distance + 0.185 * distance^2 / 50.0

In the sqlite database, if you know the distance that the plot was shot at, then compute the Pm for that distance and multiply it with the x, and y coordinate to give a mm values.

The Parkmeter (Pm) is named after James Park who used this formula in the Archers Skill Level model.
