I will add a few additional notes about Handle!
The goal was to create a tool which helps you align your time with your goals. Once that mission is broken down, we find that there must exist a system which helps you prioritize and organize, starting at the largest input, Email.
The Calendar and To-do system are at the core of what will be a larger input connection. Things you need to do + time you have to do them. The email portion is just one stream into your life.
I urge anyone, even without email, to try Handle as a tool which helps them get the important things done. We are focusing on removing friction when it comes to digital to-do lists and increasing productivity!
