Confidence-Aware Results
Every result includes a confidence percentage and short reasoning so you know when an estimate is reliable or needs another shot.

FAQ
Got Questions? We Have Answers
Everything you need to know before getting started.
Can I use my iPhone as a weighing scale?
An iPhone does not directly measure an object's weight from a photo. Scale for Grams uses visual information to provide an approximate estimate with confidence context. Use a calibrated physical scale for cooking, postage, trade, medical, laboratory, or other precision-sensitive decisions.
Is there a free digital scale app for iPhone?
Scale for Grams is available as a free iPhone download and provides camera-based weight estimates in grams, ounces, or pounds. It is an estimator rather than a certified digital scale, so results should be treated as informational.
Is Scale for Grams a certified replacement for a real scale?
No. The app provides AI-based estimates designed for quick everyday decisions. It should not be treated as a legal, trade, medical, or laboratory measurement tool. Results are informational and may vary depending on lighting, angle, and object clarity.
Which units does the app support?
Scale for Grams supports both metric and imperial unit systems. You can view results in grams, ounces, or pounds, and switch between them at any time from the settings screen.
Can I analyze an image from my photo gallery?
Yes. In addition to live camera capture, you can select an existing photo from your gallery for weight estimation. This is useful when you already have a clear photo of the object you want to analyze.
Does the app need an internet connection?
Yes. The AI analysis requires an internet connection because estimation is processed through secure cloud-based AI services. Your language and unit preferences are stored locally on your device.
Can I use the digital scale free in my browser?
Yes. The web version provides one free guest scan and one additional free scan after sign-in. Paid web scan packs are not available yet.
