# Judge a ranking gain by the users it brought

More installs from a new keyword only help if those people stay. Connect Firebase or Google Analytics 4 and asorocket shows retention after 1, 7 and 30 days, active users, time in the app and crash-free users next to your rankings and releases.

## What it does

### Retention by cohort

How many new users are back 1, 7 and 30 days after they first opened the app. Days too recent to tell are left out, not counted as lost.

### Next to releases

[Impact](https://asorocket.app/features/app-store-change-tracking) compares the share of people back after 7 days among those who arrived before a change and after it.

### More than retention

New users, active users a day, time in the app per user and, with Crashlytics, crash-free users, for App Store and Google Play apps alike.

### Read-only

asorocket reads reports through Google’s Analytics Data API and changes nothing in your property.

## Good to know

### Firebase is GA4

Firebase apps report their analytics to a Google Analytics 4 property, so one connection covers both. The service account Google Play Console uses can be reused.

### Totals only

Daily totals per app are saved on your computer. No user is ever read or stored.

**Requires:** asorocket Pro or Studio (or the trial), and a Google service account with Viewer access to the app’s Google Analytics 4 property.
