Comparisons and Conclusions Among trackers for swimmers, the Shine 2 is a fine option, albeit a simple one. I encourage you to weigh it head-to-head against the Misfit Ray. The Ray is far and away my favorite tracker of the year from a fashion...

Stylish, minimalist design ; Waterproof ; Particularly good at tracking swimming and sleep ; Battery lasts for six months

Lacks accuracy compared to trackers equipped with GPS and HR sensors ; No screen means limited use for notifications

A stylish way to track swimming and sleep, but so-so for everything else

Skinny and light ; Great battery life ; Versatile ; Good for swimmers

Not too durable ; Limited feedback ; Feature-light

The Shine 2 is definitely geared towards swimmers, as you’d expect from Speedo. That super-light waterproof design, lap tracking and excellent battery life makes it desirable for anyone who regularly hits their local pool, and the flexibility is a...

Clean-looking, well-designed app: works with iOS and Android phones; improved Bluetooth syncing; waterproof for swimming or showering; internal battery lasts six months and can be replaced; automatically tracks sleep and adds vibrations for silent...

The included strap and clip are terrible: They don't securely hold the Shine 2, nearly guaranteeing it'll be lost sooner or later. No heart rate tracking; LED lights show daily progress and the time, but can't show other data.

The Misfit Shine 2 is very thin and light. It's comfortable to wear, and does a good job of tracking your activities. The app is easy to use an offers quite a few basic and advanced features.

You'll want to be sure you get the newer style of strap, since the old version caused me to lose my first tracker. Some may not like the lack of a digital display for the time, or that the clock can be a few minutes off since it rounds to the nearest 5...

I said at the very beginning that there are loads of different fitness trackers to choose from. The Misfit Shine 2 offers a very slim design packed full of features that will cover the needs of most. If you’re a swimmer, the upgrade to the Speedo...
