iScale is loved for its unique digital experience that, while not a substitute for a real scale, provides a curious peek into the physics of your screen.

The iScale app aims to be an accurate kitchen scale by measuring pressure applied to your device's screen via 3D Touch. It provides a visual representation of this pressure. While it's presented as a weighing tool, in our evaluation, it functions as a pressure sensor, not a precise scale for objects. 

Our experience confirms that it illustrates pressure sensitivity effectively, but its practical use for weighing actual items is limited, with risks of device damage from heavy objects. This digital scale on a phone is more of a technical curiosity than a functional kitchen instrument. 

For us, the iScale app is a demonstration of sensor technology, not a replacement for a precise weighing device, and you should be mindful of its inherent limitations and the presence of in-app advertisements. Ultimately, iScale is a free digital scale grams app best used for novelty

In practical use, for tasks like quick price estimation in a retail setting or converting recipe units, the app performs its intended functions effectively. It's a straightforward utility for digital weight management. The developer states no data is shared or collected, though data, once on the app, cannot be deleted.

Ultimately, the Digital Scale to Weigh Grams app is a valuable calculation and conversion utility for digital weight figures, best utilized by those needing precise price estimates or unit changes.
