Does it work fine though? Because I haven't even heard of Google Keep, let alone have it installed.

If I need to take some notes I can't even imagine going to search through a store to find a note taking application since that should be a built in feature of every consumer OS.

The same goes for Google Photos. And I imagine that Google photos also doesn't let you edit it a column in the middle of a table. It's trivial to do in real life or in MSpaint or any real image editor but somehow exceeds the limits of mobile apps.
