What I love most about Heydai is how it helped me establish a habit of logging my time. I'm now much more aware of where my time goes throughout the day and tend to catch myself sooner when spending more time than I intended on something. All that said, I'm a bit biased so take this review with a grain of salt...
I just love Sean's app. He's put his mind, body, brain AND soul into this project. And he's truly trying to help people to prioritize their lives and be happier. The app is clean, short & sweet. And I use it daily to organize myself, as a fellow founder.
