## What is Reverse Calendar?

When was the last time I visited the dentist … when did I last change the bed sheets … when was the most recent oil change on my car … we all know the endless search for the answer. Now it’s over! With wannApp the countdown calendar , you create an event once (e.g. “dentist visit,” “change bed sheets,” “car oil change”) and tap it each time you complete it. You immediately see when you last did something and how often in a given period. Multiple entries per day or quantity details (e.g. liters, counts) are supported. All data stays on your device – JSON backup and restore included. No more endless searching; just know when it happened.
