Listant

Listant not only enables you to create lists and reminders, it also allows you to track your items and tasks by an automated day counter, with just a swipe.
The day counter allows you to track things you want to keep a record of such as new and old food items to avoid food wastage and spoiling. Additionally, you can keep a track of many routine tasks such as changing water filters, replacing contact lens and so on.

Switching between To-Do and Instant lists is easy: just swipe the bar at the bottom of the screen. The ability to order and color code different lists helps you stay organized.

The app is designed with simplicity in mind, and can be used to keep a track of various activities and tasks in your day to day life.

Optimized for all screens including iPhone 6 and 6 plus!
Check out the Listant widget in the notification center for accessing your lists quickly (iOS8 only).
