A private, offline logbook — scan a code, capture the time, place, notes, and photos.
QuickLogger turns any QR code or barcode into a rich, time-stamped log entry, captured and stored entirely on your device. No account, no sign-in, no internet.

QuickLogger is offline-first: it has no internet permission — no account, no sign-in, no cloud, no server, and no analytics, ads, or third-party trackers. Your log never leaves your device unless you send it yourself, and the only ways to do that are your phone's own Save As (export a file) and Share (hand off to another app you choose) — there is no automatic upload or sync. Entries are also tamper-evident — signed and hash-chained so edits are detectable — for general record-keeping.
