Parse, Kinvey and StackMob are great tools if you want to read/write data such as high scores from your app. But you won't have a nice editing interface for the data in the web.
If Parse is "Heroku for Mobile" then StorageRoom, the startup I am working for, is "iCloud for content".
Editors manage content in our flexible service online and data is synchronized or pulled from mobile apps.
Different use-case, but we seem to have found another problem where many devs complain. Existing CMS tools suck at this.
