It's nice to have something that reminds you of how many days until an event. It keeps you up to date and it makes me feel like the days are moving faster (summer break). It's also simple and easy which deserves 5 stars, only thing I'd like if they could add in time so it feels like time is moving.

This app is excellent for daily reminders etc. I love how you are able to customize different settings pictures etc. I highly recommend you get this app. Very happy plus it’s free!!

My favorite countdown

By far my favorite of the count downs I’ve tried. Very simple, but it works. Like the clean, classy look. A lot of them were far too busy for me.
