More isn't always better—especially when it comes to the amount of data that smartwatches can show us. For people who just want to keep tabs on their fitness goals, the Sinji Health & Fitness Smartwatch eschews all those extraneous features to focus on health tracker essentials, like monitoring your sleep, exercise, and calories. All of that tracking data can be accessed via the smartphone app. Its sleek, lightweight design means it can easily transition between exercise and normal wear. It's rated to last up to five days on a single charge, and you can take it anywhere thanks to its IP67 dust/waterproof rating. The Sinji Health & Fitness Smartwatch normally costs $155, but it's on sale today for $54.99.
