Can iphone4 imitate a jewelry scale? Just use iphone4 to weigh how many grams of gold there are. Is there such software?
Iphone4 can't imitate jewelry. Iphong4' s screen is a multi-touch screen, which has no pressure sensor and can't detect the signal of force or weight. Both Apple's new wearable device and Apple Watch's screen have pressure sensors, which can achieve this function. There is no such APP at present. Iphong4 has no such software.
