Need a simple write up for an App

We need a simple description written for an Android/iOS app.

The write up will:
1. be used on the app's page on an app store and/or website
2. be between 2000 to 4000 characters (not words)!!
3. describe the app and it's functionalities to a lay man
4. unique and straight to the point

You will need to download the app and use it to understand it how it works.
If all goes well, we'll need more write-ups done for other apps.

The current app is in beta on Google Play
https://play.google.com/apps/testing/ng.catchup.android

If you are new at this you can look up descriptions for apps on Google Play or App Store
