App SW 2.1.0

AUTO RECONNECT When you lose connection with your BOWdometer, it will reconnect automatically in most conditions. You still need to pair it at the start when you launch the app but it should cover mid-session disconnects. SHOT ANGLES You can see you shot angles (pitch, yaw, roll) in the shot details slider in current and previous sessions. For current, active sessions it may take a bit of time to show up because it needs to get computed after the shot. Slight updates to the shot goal slider and a couple small bug fixes.

App SW 2.0.0

  • Set once during onboarding
  • Can modify in Settings (gear on top right corner of dashboard)
  • Can modify in Menu > View Profile > Reset Shot Goals
  • Refreshes every Monday morning at 12:00 am
SESSION MODES For each new session on the app, you can choose between 2 different session modes as long as you have BOWdometer FW 2.0 or higher loaded on your BOWdometer (see instructions here) You can only switch between modes in the app (not on the BOWdometer itself) When you create a new session on the BOWdometer, it will also be in the same session mode as the last session CLASSIC MODE Take shots and see your feedback in a "free play" mode. Great for working on form changes, evaluating new accessories or tuning your gear. Shooting in Classic mode won't affect your Xi Level. In Classic Mode, your Xi will be any number between 0 and 100. It will not be centered around '50' the way it is in Level Mode. This means there is no "right number" - it will be unique to everyone and their personal equipment. For people who were on the BOWdometer Product Beta, Classic Mode is what you tested during that Beta Classic Mode Xi shows more decimal places than Level Mode so you can see more detail for similar shots LEVEL MODE (same as what you're used to from previous versions) This is how your BOWdometer has worked for all sessions in the original app. Use this to monitor your practice and work on getting to a higher Xi Level. When you level up, the sensitivity increases to really challenge yourself to hone in on your skills! SESSION GOALS AND NOTES Creating a new session on the app now lets you set shot goals for the session, use the slider to set your session goal and then track progress towards it while you shoot You can type notes about the session when starting that are stored so you can review them later Session notes can be updated at the end of the session on the session summary screen PAUSE AND CONTINUE SESSION
During an active session, you can pause your session in the app. This allows you to go back to the dashboard or move around in the app. The "Continue Session" button will only show up if you pause through the app and don't force quit the app. If you start a session without the app connected, it will put your session into the Previous Session screen and keep it updated, but it will not let you open the Active Session screen. We'll add that in sometime later. END SESSION In the original app, there was no way to end a session. Here, we have a button to end a session. It's important to note that if you keep shooting on your BOWdometer without starting a new session, those shots will get added to the "Previous Session" once you've ended on the app. This may feel confusing but we have plans to clean it up later!

All your shot information is stored in the cloud so you can switch phones and recover all your information easily. It's secured and tied to your user account. RESTORE YOUR BOWDOMETER
If your BOWdometer gets corrupted during updates, you can now restore the latest snapshot of your BOWdometer data from the cloud through the "Manage Devices" menu when your BOWdometer is connected. This restore includes total count, last session details and level. In the beta, this is open for anyone to try, but in the main app it will be opened up only for users who need to access it. WARNING: This changes the data on your BOWdometer to the last known snapshot, you may lose some recent shots! BOWDOMETER FIRMWARE UPDATE New versions of BOWdometer Firmware will now be updated through the App. It should sync your shots for you as part of the procedure. There are features that may force you to update. For the beta users, we'll continue to push new test firmware to you early as we add more features! FEATURES FROM ORIGINAL APP
