App store relaunch

[mreider]

We are re-launching the apps in the store. The apps will have a new name (peacenik) and new logos.

We are going to create new apps for Google Play and also the Apple app store.

In the app store this should run on a variety of devices. Today it is only on iPhones. iPads should work too.

@ksiger-app please work with @inna-matvienko as follows:

1. Tell @inna-matvienko how many images we need, and of what sizes they should be.
2. @inna-matvienko create imagery and attach to this story.
3. Launch!
