The true weight calculation happens by tapping into specialized pressure-sensing screen layers, such as Apple's legacy 3D Touch matrix. These arrays measure the physical displacement of the glass when force is applied, converting mechanical pressure measurements directly into an approximate metric weight (grams) on screen. Step-by-Step Guide to Weighing Items
: This only works on iPhones with physical 3D Touch hardware. Newer models using "Haptic Touch" (iPhone 11 and later) generally cannot measure weight this way. Weight Limits
Innovations like and online screen rulers represent a fascinating shift in how we interact with our devices. They turn a communication tool into a multi-sensor measurement laboratory. Whether you want to impress friends by weighing a strawberry on your phone or you need a precise ruler for a last-minute design fix, these free web tools are incredibly resourceful. Touchscale.ml.mk
成功访问网站后，你将看到一个简洁的界面：蓝色边框，中央是一个白色方形称重区，以及“去皮”（Tare）和“灵敏度”（Sensitivity）等按钮。请遵循以下步骤以获得最佳体验：
Touchscale is a free, browser-based web application that attempts to turn your smartphone or tablet into a makeshift scale. It utilizes your device’s or Haptic Touch capabilities (on iPhones) or, in some implementations, the pressure sensitivity of a stylus or finger on certain Android devices and iPads. The true weight calculation happens by tapping into
: Most versions include a "Tare" button to reset the scale to zero, allowing you to account for a container or surface protection (like a spoon). Device Compatibility
According to technical reports, the application relies on the built-in pressure sensors below the screen to translate the vertical force into a corresponding weight reading. For the measurement to be stable and relatively accurate, the object must make full contact with the screen and maintain a consistent center of gravity throughout the measurement. Newer models using "Haptic Touch" (iPhone 11 and
If you are looking for formal research into the technology behind such apps, these papers explore similar 3D touch force estimation and capacitive sensing: TouchScale : Weigh things on your iPhone!
Most standard Android displays only register capacitive surface area rather than downwards pressure. Select legacy models with force-touch displays will support full functionality. Crucial Safety Tips for Screen Protection
