AppPresser 3 has launched with significantly improved speed, free push notifications, and a dashboard for building your app within the AppPresser website.
Starting at only $199 for the year, AppPresser is a really great way to get an app up and running without spending a ton of money on a totally separate application. The improved offline support and notifications make it much more compelling than it (and any other app wrapper) used to be.
The tight integration with WordPress would make this my personal go-to choice. I especially like that you can feed AppPresser any WordPress REST API endpoint for access to lists of posts.
