The in-app upgrades to Premium/Coached used to be lifetime upgrades. Once upgraded you never had 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.

Nowadays, Premium and Coached are subscriptions. Once subscribed you get the functionality you paid for. Subscriptions may end for two reasons; you, the user, canceled the subscription, or there was an issue in the payment for the new period. There is a grace-period when this happens (and you get a mail from Google). When the grace-period has expired the Premium or Coach functionality is not available anymore and you have to (re)subscribe.

Subscribing to Premium/Coach 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!

Use case: you have used Artemis on your mobile device for some time now. Now you want to transfer this data to a new mobile device.

First requirement is that, you need to have either the Premium or Coached license.

In the free ArtemisLite version, you can backup your data to the SD card, but in AndroidOS, files written to the SDCard from within an app are not visible in your file-browser. This is a Google/Android privacy decision, not ours. The procedure; backing up to SDCard and then trying to find the file and transfer it to the new device, will not work.

To transfer your data to a new device:

Open ArtemisPremium/ArtemisCoach on your old device and go to Options. In Options, scroll down and choose Database. Now, login into your Google account (if you haven't already) by clicking on Manage Google login. A succesful login brings you back to the main screen. Then, go to Options and the Database again and find the section Google Drive and click on Backup As. This allows you to create a backup on your Google Drive (in the cloud).

On the new device, install Artemis and open ArtemisPremium/ArtemisCoach and also login into your Google account. When you are logged in, find Restore database in the Google Drive section in Options/Database and click that. Then find the backup in your Google drive and select it. A dialog will show if the restore was succesful.

Note that restoring a backup file will overwrite your current database

In Artemis, a round is a collection of entries. You might start a round with pracise arrows, then shoot some kind of qualification format and finally end with multiple eliminations. Artemis only binds all these entries together and call it a round. The 'score' of the round is the total score of all entries that where either shot indoor with 30 arrows or outdoor with 36 arrows. All other entries do not count for the total score.

There are many preset rounds, but if you want to create a custom round, do the following;

• Create a new round with the correct rules and select as 'roundtype' 'custom'. This will create an empty round.
• Create the qualification entries and each elimination stage by hand as individual entries.
• Then multi-select all created entries and press the paperclip+ symbol (this will show the round list) and select the empty round to add them all to this empty round.

We are used to see arrow values on a scorecard in a high-low order fashion, but did you know you can show them in shot order as well? Go to Options then Scorecard and uncheck Sort on value. This will show the arrows on the scorecard in the order they were shot (or plotted), which may give you some nice insights in how you do during an end.

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.
