What I’ve Been Looking For

This count down app fixes every problem I’ve had with previous ones. It is sleek and user friendly. It allows me to easily view the countdown from the widget view. All around great application 👍🏼

If I could only give it 6 stars

Without this app, I would forget every single important date that has ever happened to me or anyone in the world that is significant. Bravo Clifford Panos.

not annoying, great design!

This app doesn’t flood you with stupid notifications like apps always try to, plus it’s intuitive to use and honestly really elegant
