A vision model estimates the object and material, then returns an honest low–high range, not a fake-precise number.

Save & track it

Every estimate is saved to your account and synced across devices, so your scan history is always one tap away.

Ranges, not guesses

Every estimate is a range.

A single "precise" number is a lie a camera can't back up. gramscale always shows a low–high range and labels its confidence, straight from the vision model that analyzed your photo.

Weigh a whole batch in one session.

Scan objects one after another and gramscale keeps a running total and count as you go, up to 20 items per session, then export the summary. Free accounts get 3 single scans a day; Pro removes the daily limit and unlocks batch mode.
