Is there a way to know when or how many times a user has installed the app?

We’ve heard some reports of the app “disappearing” from user’s phones. I’m wondering if there’s a way to know how many times the app has been installed on a phone.

There’s a telemetry field: boot_time:2_1:to_replication that represents time to complete “initial” replication, which I would assume only happens the first time the app is installed. Would the count of to_replication be a possible proxy for knowing how often the app was installed on the phone?

Hi @michael

You would also see boot_time:2_1:to_replication when:

  1. the user logs out and logs in with a different account
  2. the app data is deleted (wipe) without resintalling

Cool thanks. A few follow-up questions.

  1. the user logs out and logs in with a different account

OK. If it’s the same phone, presumably the metadata.deviceId would be the same for the different user accounts though, correct?

  1. the app data is deleted (wipe) without resintalling

Not sure I understand. Are you saying it writes that telemetry data even though it is just going to immediately be deleted (and probably not synced to the server anyway)?

  1. the app data is deleted (wipe) without resintalling

Not sure I understand.

If you just wipe data, and login again, without actually reinstalling the app, you will get that replication telemetry entry.
