Mobile apps for Blogs

Hi guys,
Recently we launched new service https://blogtomobile.com, where we create mobile apps for a blog for free. All is based on profit share from mobile adverts. You don't risk anything but you can get a lot of new followers, increase loyalty and earn more money.

Every mobile app we made is uniquely adapted to blog content. Blogger doesn't have to do anything, we do all the stuff. If you are interested check blogtomobile.com

What do you think about having a mobile app for Blog? Or maybe you already have one?

Is the app universally ready for all mobile devices? or specific models only?

The following are some of the mobile apps
WordPress app.
Google Analytics app.
Evernote app.
The Pocket app.
the Cloze App.
the Slack app.
the MagicJack app.
Google Keep.
