It works OK, when it works.

For the most part, the app works as billed. But, occasionally when sending texts, it doesnt mark the message as read. Or it will mark the message you send as unread.

The fun part is going back to the app after using another app, it crashes upon reopening for no apparent reason. This has been happening for about 3 weeks. And you can send all the crash dumps you want to Google, no one cares!
