Staying alert when you have serious work to do is not always easy. You could always get some coffee or exercise. Vigo can also help. It tracks your alertness over time and nudges you when you are too sleepy. Vigo is easy to use. Just wear it when you need to stay alert, connect Vigo to your mobile device through Bluetooth, and customize how it behaves.
Vigo tracks your alertness over time. Its companion app visualizes the data to give you a better idea about the patterns and how you can change your daily routine. Vigo even offers smart recommendations. This awesome product is on Kickstarter.
