The motion sensors can detect G-force measurements, which record acceleration and deceleration, at speeds up to 256Gs. With more room inside each iPhone, there is space for a more impressive gyroscope and dual-core accelerometer. The iPhone also supports Apple's new Crash Detection feature, with input methods better suited for the smartphone's larger form factor. This data is complemented by GPS data that detects speed changes and microphones that look for sounds commonly heard in severe crashes. An all-new collection of motion sensors, notably a better gyroscope and accelerometer, monitor data when the Apple Watch is worn in a vehicle in motion. Apple simulated various types of accidents, including head-on, rear-end, side-impact and rollovers, to develop the algorithm that powers Crash Detection. It tested crashes at professional labs and studied the standard data points found in car accidents. To make Crash Detection possible, Apple created an algorithm that intakes data from both old and new input methods on the Apple Watch.

A blood-oxygen sensor followed, and now the Apple Watch Series 8 and Ultra include a body temperature sensor. Then came a more advanced optical sensor capable of recording electrocardiograms and detecting signs of atrial fibrillation. The first Apple Watch started with a heart rate sensor and constantly took heart rate readings.

It's a device fit for kids, adults and the elderly - with health tools beneficial to people of all ages. From the beginning, the Apple Watch has always been a smartwatch characterized by its fitness, health and safety features.
