Aim the camera at a label, tap Capture or let auto capture read it, and every serial number lands on the next line of one list. No Lens-to-notes flipping: fix before adding, duplicates skipped, undo, export TXT, CSV or JSON, no account, offline, free.
Serialpad reads the text on a label with your camera and adds it to one list. It is not an upload-a-photo converter, not an asset database and not a barcode scanner. The reader is tuned for Latin letters and digits, so check each read before you add it.
Serialpad reads serial numbers, asset tags and model codes off labels with your phone camera and puts each read on the next line of one list. Tap Capture or turn on Auto capture, fix a read before it goes in, and the same text twice is skipped. It is tuned for Latin letters and digits.
No sign-up. Text is read on this device, the camera picture is never uploaded and the list stays in this browser. The first read fetches the text reader (about 7 MB) from this site once; then it works offline.
Example: set the note Rack B3, capture every label in the rack and export a CSV.
