We don’t track the number of users Monal has. We do see thousands of downloads in the App Store statistics. Any user counting and crash tracking provided by Apple is strictly opt in only. So it always undercounts. However because ever user registers a push device with the push server we do see how many devices there are using Monal. This is a very rough estimate that is a bit inflated because you can reset your push deviceids. With all that said, there are currently:
61,953 devices registered to receive push notifications.
On January 31th the push sever sent 77,199 push notifications. Which comes to just under one a second.
