Changed

The app you didn’t know you need… until you need it.

Phone acting up? Find what changed.

Changed helps you investigate phone problems by comparing the changes Android makes visible with when you first noticed an issue. Review ranked leads, open dated evidence, and use Android settings to investigate further.

LOOK BACK AT RECENT CHANGES
See visible app installations and updates, observed permission changes, system details, and storage changes in a searchable timeline. Android-reported package dates can provide a starting point when you first install Changed; they cannot reconstruct a complete past history.

COMPARE SNAPSHOTS
Save named snapshots and compare them with each other or the current device state. See the differences without losing your saved baselines.

REVIEW APP ACTIVITY
Optionally enable Android Usage Access to view the usage and network statistics Android permits. Access is your choice and can be revoked in Android settings. Unavailable readings are identified rather than treated as zero.

LOCAL AND PRIVATE
Diagnostic processing and history stay on your device. Changed has no account, ads, subscription, analytics, or diagnostic uploads. Delete recorded history in the app; saved snapshots remain until you delete them separately.

HONEST ABOUT THE EVIDENCE
A close timing match is a lead, not proof that an app caused your problem. Changed cannot recover every earlier event, automatically fix your phone, or diagnose every issue. Coverage varies by Android version and device. Notification-content analysis and activity-anomaly baselines are not included in this release.

Requires Android 8 or newer. This is an early release, with continued improvements planned for evidence quality and device coverage.

Designed for Android phones and tablets. Android TV and NVIDIA Shield TV are not supported in this release.
