Help and answers for Database Viewer: MDB & ACCDB (AccessViewer) on iPhone, iPad, and Android.
Email us any time at w4n9we1@gmail.com — include your device model, OS version, and the file format you are working with so we can reproduce the issue faster.
Microsoft Access (MDB, ACCDB — Jet 3/4/2007+), SQLite databases, Excel workbooks (XLSX), OpenDocument spreadsheets (ODS), dBase files (DBF, dBase III), CSV and TSV text tables, and SQL dump scripts (SQLite dialect).
Tap Open file and pick your database from the Files app (iOS) or your file manager (Android). A health check runs automatically before the file opens, so you know right away whether anything is wrong.
No — and that is by design. Edits are made on a private working copy stored inside the app. Your original file is never modified; exports are always written to a new destination you choose.
Open the app, go to Files → Settings, and use Restore purchases with the same Apple ID / Google account you purchased with. Purchases are managed through RevenueCat, so your Pro entitlement follows your account on both platforms.
No. Pro is a single one-time purchase. Pay once, keep everything.
No. Database files, health reports, query results, and exports are processed on your device. The app contains no account system. See the Privacy Policy for details on advertising and purchase processing.
The health check explains exactly what is wrong — unsupported format version, encoding problems, or damaged regions — and suggests next steps. If you believe a supported file is being rejected, email it to us (or describe its properties) and we will investigate.
