My cofounders and I have developed the first calendar app that integrates health data from wearable devices to help you plan their schedules around you peak productivity times. We calculate your energy levels throughout the day using your sleep data, circadian rhythm, subjective feelings, and many other metrics that we'll be adding in the future!

It’s now available on the App Store, Play Store, and even as a Chrome extension.

We've also submitted it to F24! We hope you'll give it a try, and we're excited to hear your feedback!
