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

The Digital Scale to Weigh Grams app functions primarily as a calculator for weight-related pricing and a digital unit converter. It enables you to calculate product prices by inputting weight (grams/kilograms) or to find the weight from price and quantity. It also offers quick conversions between grams, kilograms, and milligrams. 

A useful ‘Sell list’ feature allows for summing multiple calculations. While its name might suggest physical weighing, my team's assessment confirmed it's a computational tool. However, it only performs calculations based on entered weights, a common point of user confusion.

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.
