Stable
EchoSweep
The stable app version intended for regular use.
Private storage review
See what takes space. Keep control of what changes.
EchoSweep is designed to inspect files and media on your Android device, identify exact duplicates, review similar photos, and support deliberate cleanup without an EchoSweep account.
App versions
Two EchoSweep versions
EchoSweep is maintained as two distinct Android app variants so stable use and development testing remain clearly separated.
Development
EchoSweep Dev
A separate development and testing variant for evaluating changes independently from the stable app.
Availability, version numbers, and testing channels may change independently.
Product principles
Local-first by design
On-device analysis
File inventory, hashing, byte comparison, and similar-photo analysis are designed to run on the device.
No EchoSweep account
The app does not require registration, login, cloud sync, or an EchoSweep account for its storage workflows.
Explicit cleanup
Cleanup actions are user initiated. Available behavior may include quarantine, restoration, local trash, or permanent deletion depending on the app version and Android access.
Clear boundaries
What the app may inspect
EchoSweep may access file names, paths, sizes, dates, media types, file contents needed for duplicate comparison, and image data needed for similar-photo analysis, within the storage areas Android makes available and the permissions you grant.
