Barcode local
The visitor points the camera at a barcode. The tool decodes the digits on the device and shows them. The frame is discarded. The visitor copies the digits into the calorie search themselves. The same search exists in German, French, Spanish and Portuguese, so the host ships all nine languages.
Use the camera, microphone, motion or timer on this device. Frames stay here; the result is a number or a card.
This is a general-purpose tool, not medical, legal or financial advice. Figures are estimates from published food data or arithmetic. A qualified professional owns decisions that affect your health.
How to use it
Inputs are a camera frame that stays local. Computation decodes a symbology. Output is the digit string.
Result
The tool runs in your browser. Nothing from the camera, microphone or sensors is uploaded. With JavaScript off, the worked example below is still computed on the server.

The calorie search is where those digits, or the product name beside them, become nutrients.
Keep the result in an account
TempoLife keeps food, movement and sleep in one private place, so this result can become part of a day instead of a one-off page.
