Voice labels — talking stickers with a QR code

The voice is stored in the browser where the label was recorded. On another phone the sticker still opens and reads the label’s caption with speech synthesis. To hear your own voice there, turn on cloud labels (Premium) — the voice then plays from the sticker on any phone — or save a copy under “Cloud and backup” and load it on that phone.

Start scanning and move the phone slowly over the items about 6–10 inches away. While there is no code you hear soft clicks; on a find there is a double tone and a vibration, then the recording. A code of 3 cm (about 1¼ inches) or more reads without precise aiming, and in “Keep scanning” mode the camera stays on so you can check a whole shelf. On Android, NFC tags are easier still: just touch them with the phone.

Yes. Scan the sticker or pick it in “My labels”, press “Edit” and record a new voice — the label number in the code stays the same, and the old sticker plays the new recording. The caption printed on paper does not change.

Under the sticker on the right the tool says from what size the code reads reliably: a label without a caption needs about 23 mm (just under an inch), a long caption makes the code larger. For jars and boxes 35–45 mm stickers work well; for bottles and tubes, 40 mm round stickers or 40 × 30 mm tape on a label printer.

Labels can be written from the page in Chrome on Android. NTAG213, NTAG215 and NTAG216 stickers work: NTAG213 holds a label with a short caption, for a long one take NTAG215 or 216. On metal surfaces use anti-metal tags. iPhone XS and newer and Android phones with NFC read such a tag with a tap.

No: the labels live in this browser’s storage. The tool asks the browser not to delete them when space runs low, but clearing history and site data erases them, and Safari on iPhone may erase the data of a site you have not opened for a week. Save a copy as a file after making new labels — it loads back in a second; cloud labels (Premium) are kept on the server and survive clearing.
