The new iPhone may get all the attention and they look beautiful but let's face it, its just the same old with some insane price options (£1400+!).

I am a little more excited about the Apple Watch 4. The smartwatch scene has stagnated a little especially with Wear OS, this will hopefully improve with the Qualcomm Snapdragon 3100 but in the meantime, Apple is the ones pushing ahead with smartwatch innovation.

Inside the new Apple Watch 4, we see Apple transition to a new SiP (Silicon in Package) design with a new S4 SoC containing for the first time a custom Apple-designed CPU and GPU. They are a little coy about specifics but it is a dual-CPU that is 64-bit capable and is promised to perform twice as fast as it’s predecessors – which used Arm’s Cortex A7.

The S4 SiP includes a new accelerometer and gyroscope functionality that has 2x the dynamic range in terms of measurable values, as well as able to sample data at 8x the speed. What this allows Apple to do is to collect a lot more data at higher accuracy and try to determine the scenario that you’re in. For example, Apple claims the new watch is able to discern between falling, tripping and slipping just based on the movements that the person makes.

The screen has been improved considerably with a higher screen-to-body ratio on the watch and you now have more watch face options.

The crown has been updated to provide haptic feedback trying to mimic the  “clicking wheel” feel such as in more mechanical dials, or more aptly, the clicking of a mouse wheel when you scroll with it. The haptics here is enabled not by the crown itself, but by a vibration motor inside the watch.

Perhaps the most interesting upgrade is the heart rate monitor which now includes  ECG (electrocardiogram) functionality and is apparently the first device to do this with approval from the US FDA. It is a bit of a niche feature but it is a welcome addition and it will be interesting to see if it can be expanded further than ECG readings to more accurate day to day tracking.

The ECG is used to detect abnormal heart rhythms and can be used to diagnose common and serious conditions such as ventricular fibrillation.

The improved accelerometer, gyroscope and HRM, as well as the ability to swim with it, makes this quite an appealing sports watch for the casual athlete. Though it is unlikely to ever compete with
