Heft - Estimate Weight AI

Heft is the AI weight estimator that turns your iPhone camera into a portable scale - instantly. Snap a photo of any object and get a weight estimate with an honest confidence range.

No scale? No problem. Whether you're sizing up a parcel before the post office, weighing luggage before a flight, or just curious how heavy something is - point your camera, tap the shutter, and Heft delivers a weight estimate with the AI's actual confidence shown next to it. No fake precision, no gimmicks. You see exactly how much the AI trusts its own answer.
