Apple Watch Series 4 review: Improved design, useful features make it the best

Not that there was any doubt earlier. It is no surprise then that the Apple Watch Series 4, which launched in India around three weeks ago, is the best smartwatch to buy right now. The Apple Watch Series 4 still has the same square shape with rounded corners, but it's almost 1mm thinner at 10.7mm compared to 11.4mm Watch Series 3. But Apple is clear: A smartwatch has to be an ultimate health and fitness tracker, and Apple watch Series 4 is big on this functionality because of the first-grade heart rate tracking built into it. Should you buy Apple Watch Series 4 If you want a smartwatch and don't mind spending Rs 40,000 on it, get the Apple Watch Series 4.
