Understand reachable devices, stale FCM tokens, platform mix, activity windows, and campaign history before you send another Firebase push.
A raw token count is not a reachable audience. Tokens go stale after uninstalls, app data clears, inactivity, and device migrations. Without health reporting, campaign planning is based on inflated numbers.
Pushbrain tracks device metadata and send outcomes so you can see active, stale, platform, environment, permission, and reachability signals around your Firebase push audience.
Open rates are only meaningful when the denominator is honest. Pushbrain helps separate registered devices from recently reachable devices so campaign numbers are less misleading.
Pushbrain prunes stale tokens after send responses and exposes aggregate health signals, reducing the maintenance work that usually hides inside direct FCM integrations.
Usually only at send time, through per-token errors. Pushbrain processes those outcomes and keeps audience health visible.
Yes. Pushbrain supports push-specific segmentation by platform, environment, permission status, and activity recency.
