How is the monthly active users (MAU) count calculated?

MAU (Monthly Active Users) is the number of unique users who opened your app during the month. It is counted per user, not per device - the separate Monthly Active Devices (MAD) metric counts unique devices.

Pushwoosh counts MAU by User ID, so the result depends on how your project is set up:

• If you set a custom User ID through the SDK, all of that person's devices and contact methods are grouped under one profile. Someone using both a phone and a tablet counts as one active user.
• If you do not set custom User IDs, the User ID defaults to each device's hardware ID (HWID), so every device counts as a separate user.

MAU for billing is counted differently from the analytics metric above: a user counts toward billable MAU if they received a message on any channel (push, in-app, email, SMS, messengers) during the month, even if they have no push token. Users are deduplicated by User ID in the same way. Your billable MAU for the current period is shown in the Usage block of My account → Billing; see the pricing page for rates.

You can see analytics MAU alongside Total users and DAU in the Unique users widget on the Project overview.
