One app. Every everyday job.
ScanFlu isn't a single tool — it's a connected toolkit that covers the small file jobs you hit every week. Your files stay on your device unless you choose to share them.
QR & Barcode
Scan codes with a live preview gate, create QR/barcodes — including AES password-protected ones only ScanFlu can open.
Photo tools
Compress to a KB target you choose, resize, passport photos, batch shrink, on-device OCR text extraction.
Clean Metadata
See every hidden tag in your photos — location, camera, AI labels — in plain words, wipe them clean with proof, and share as one ZIP.
PDF tools
Create PDFs from photos & documents, compress, merge, split, unlock, annotate and fill & sign.
ZIP tools
Pack files into ZIP archives and extract them again.
Excel & CSV
Turn a photo of a table or receipt into a formatted .xlsx spreadsheet, or convert CSV files.
Docs & Code
Write text and Markdown notes, edit JSON and Word files, and code in Python, Java, C++, JS, Dart & more — JavaScript runs for real, on-device.
Calculators & Converters
Scientific calculator, unit & currency converters, age, stopwatch, timer and world clock.
Money & Billing
A personal money ledger plus invoice & billing documents you can share as PDF.
Your files stay on your device — until you say otherwise.
ScanFlu does the work on your phone, so nothing sits on a server waiting to leak. Only the optional Photos → QR sharing uploads anything — and only when you start it.
- 100% offline core tools — PDF, photo, ZIP, Excel, notes, calculators.
- No account, no email, no password for anything except one optional feature.
- Nothing uploaded automatically — sharing happens only when you tap Share.
- Protected by Play Integrity & App Check against tampered copies.
Photos → QR: share 10 photos with one scan.
The single feature that uses the cloud — for when you need someone else to get your photos at full quality.
- Opaque, unguessable links — resolved server-side, never exposing storage paths.
- Only you can mint links for your own uploads (ownership-checked).
- Auto-expiring galleries with viewer + download built in.
- Google Sign-In required — just for this feature, so shares are tied to you.
Geo Photo: prove where it happened.
Capture a photo with live GPS, timestamp, QR and mini-map baked into one shareable sheet — or a signed .sf bundle that opens in a rich viewer for ScanFlu users.
- Location on demand — permission is asked only at capture, never before.
- Two ways to share — universal PNG for everyone, verifiable
.sffor ScanFlu users. - Nothing uploaded by us — sheets leave only when you tap Share.
- Open .sf anywhere — recipients with ScanFlu get photo + live map + one-tap navigation.

Free. Supported by short ads.
