## What is Heft?

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.

HOW IT WORKS
1. Point your camera at any object
2. Tap to capture
3. Get an instant weight estimate with confidence range

Heft is transparent by design. Every estimation comes with a confidence percentage and a weight range, so you always understand how reliable the result is.

FEATURES
• Instant AI weight estimation from a single photo
• Confidence ring shows estimation reliability at a glance
• Measurement history - every estimation saved and searchable
• Support for kilograms, pounds, ounces, and grams
• Light and dark mode
• Home screen widget for quick access to recent estimations (Heft+)
• CSV export for your measurement data (Heft+)
• Clean, minimal design - no clutter, no ads

LIDAR-ENHANCED ACCURACY
On iPhone Pro and iPad Pro with LiDAR, Heft measures real object dimensions using ARKit depth sensing. These physical measurements are sent alongside the photo to the AI, producing significantly tighter confidence ranges.

PRIVACY FIRST
• Photos are processed transiently - never stored on any server
• All estimations stored on-device only
• No personal data collected
• Analytics are anonymous (Firebase Analytics - IDFA disabled, no ad tracking, no cross-app tracking)
• See our privacy policy for full details

PERFECT FOR
• Shipping & postage - estimate parcel and package weight before the post office
• Travel - will this bag be overweight before the check-in counter?
• Kitchen & cooking - quick weight checks without a food scale
• Curiosity - "How heavy is that rock?"
• Education - teach kids about mass and weight

Heft is built in Australia with a focus on honesty, privacy, and delightful design.
