Can I use the smartwatch app without connection to my phone?
Yes, the smartwatch app can be used without connection to your phone.
But you should run the phone app Moon Calendar Watch once per week to update the moon data on your watch.
Please watch the video


Why does the smartwatch app say "Please run the phone app"?
You should run the phone app Moon Calendar Watch once per week to provide new moon data for your smartwatch. Make sure that the watch and the phone are connected before opening the app Moon Calendar Watch on your phone and on your watch.


Where is the Smartwatch Refresh button to download new moon data from the phone?
On the Fitbit and Garmin watch:
At the top of the watch app: tap the "..." button and then the Refresh button to update the moon data on your watch.
Please don't forget the Fitbit "Sync", shown in the video, before starting the watch app Moon Calendar Watch.

Please watch the video

On all other watches you do not need a Refresh button, everything should happen automatically.
Just make sure that the watch is connected to the phone before opening the app Moon Calendar Watch on the watch and on the phone.
When you open the phone app Moon Calendar Watch it will automatically send the moon data update to the watch app.


Why is the watch display black when I download moon data to my smartwatch?
If the connection to the phone is slow, the watch display may switch off during the download. Just tap the watch screen to switch the display on again.


The download was interrupted by a watch Notification display and stopped working.
What should I do?
Please press the Back button and try again.


Why does the Fitbit app show a "Connection Error" when I try to download new moon data from the phone?
Please be patient, the Fitbit connectivity is slow and unreliable .

The Fitbit "Sync" step, shown in the video, is very important. Don't skip it and make sure that the watch app Moon Calendar Watch is closed during the Sync.

Please try this:
1.) On your watch: close the Fitbit app Moon Calendar Watch.
2.) Open the Fitbit phone app and Sync it with your watch, wait until it says "a moment ago"
3.) On your watch: open the Moon Calendar Watch app, tap "..." and then the Refresh button
4.) Wait at least one minute for "Connecting..." (the Fitbit is slow). If the watch display goes black during the download, just tap the watch screen to switch the display on again.

Steps 1) and 2) are really important, don't skip them.

Unfortunately Fitbit is doing a terrible job to recover from connectivity problems .
So you may have to repeat these 4 steps several times.

Try it with different Connectivity settings:
* WiFi on, Mobile Data off
* WiFi off, Mobile Data on

Sometimes it helps to Restart your phone and your watch (power off - power on) and then repeat the 4 steps above as shown in the video

Sorry, we can not help you with watch connection problems.
This is a problem in the Fitbit phone app, which is responsible for all the communication between watch and phone. Fitbit had promised to fix these problems a long time ago, but so far they have failed to do this: https://community.fitbit.com/t5/SDK-Development/Companion-messaging-and-writing-a-file-Not-working/m-p/2400027#M2173

But if you make sure that Fitbit watch and phone are connected and
if you follow the "Sync" steps correctly, as described above and shown in the video, you should be able to get it working.
