Heft uses your iPhone camera and AI to estimate the weight of everyday objects instantly.
No scale? No problem. Just point your camera, tap the shutter, and Heft delivers a weight estimate with an honest confidence range. No fake precision, no gimmicks. You'll know exactly how much the AI trusts its own answer.
