Scan → save → share.
A deliberately simple Android document scanner for people who do not want to manage files.
The current stable release keeps the full Google scan editor with page previews, crop and rotate, and Google's filter gallery, then continues directly to the ScanIt Result and sharing actions. The redundant ScanIt intensity/shadow screen has been removed. The APK also includes the Recent scans dashboard, reusable visual signatures and stamps, measured and custom PDF size targets, and six selectable language modes. Settings now include a localized Buy Me a Coffee button; support remains optional and does not unlock features. Settings now save after each change, survive navigation and updates, and default to deleting saved PDFs after sharing while retaining saved images. Visual signatures and stamps can be moved directly on a larger preview, resized and rotated with gestures, or fine-tuned from the collapsed Manual position panel. ScanIt now supports Android 13 and newer while keeping the same Google scanner, sharing, saving, and verified cleanup behavior.
The Result screen now keeps the document preview prominent and opens a full-screen zoomable viewer when tapped. File details can change a document's PDF name, size, and folder, and can change its image name, size, format, and folder. Image exports support exact Original files, high-quality JPEG, and lossless PNG. A Recent scan opens directly when tapped. The stable Actions panel extracts Latin-script text from all pages, exports it through Android's file picker, or detects QR codes and barcodes on the current page using on-device ML Kit models delivered by Google Play services. The recognition model may download before its first use; Actions report that state and can be retried afterward.
Result pages now swipe horizontally and reveal the edge of the next page. Rescan, Sign / stamp, and Actions are compact accessible buttons, while File details groups PDF and image changes into compact Size, Format, and Location controls. Externally deleted PDF and image outputs are shown as Deleted and can be recreated directly with Save without reusing stale provider locations. After a full app restart, ScanIt opens a fresh scanner session instead of reopening the previously viewed Result; completed scans remain available from Recent.

Sending a scanned document should not require understanding folders, file managers, or export dialogs. Open ScanIt and the scanner starts. Capture one or more pages, check the result, then share the PDF or images through Android.
The interface is monochrome and follows the system language by default. English, Czech, German, Spanish, and Simplified Chinese can also be selected from one compact language picker in Settings.
ScanIt was built with AI-assisted coding and design. The maintainer reviews the source, release artifacts, and real-device workflows.

- Measured PDF size goals of Original, 200 KB, 500 KB, 1 MB, 5 MB, 10 MB, 20 MB, or a custom 1 KB–500 MB target; ScanIt reports the actual size when a readable result cannot meet the selected goal.

The scanner processes document content on-device. ScanIt keeps at most eight temporary scan directories for Result and Recent scans. Android may clear these working copies. PDFs saved to Downloads or a selected folder and images saved to Gallery remain until the user deletes them.
- The public Google Play and GitHub variants contain no app-owned
INTERNETpermission. - Google Play services and ML Kit may process diagnostic and usage telemetry; scanned input remains on-device according to Google's ML Kit documentation.
- ScanIt does not send scanned content to a maintainer-operated server.
- File sharing uses scoped content URIs with read access granted to the selected receiving app.
- Saved-output changes are verified before activation and remove only the exact previously tracked output.
- Copied OCR and barcode results are marked as sensitive; detected payloads never open automatically.
- Android backup and device transfer are disabled for ScanIt app data.
- Sharing and printing hand a user-selected document to another app or service under that recipient's terms.

- Android decides which compatible apps appear in the Sharesheet.
- Recent scans are temporary working copies, not a permanent document library.
- Android 17 has no
maxSdkrestriction but has not yet been device-tested. - Google Play publication is still in testing; do not describe the app as a production Play release yet.
- Visual marks do not verify identity, authorization, or document integrity.
- The repository does not contain production signing material.

ScanIt is free to use. If it saves you time, an optional tip helps fund future maintenance. It does not unlock features or change support priority.
