IM+ is a messenger client for both iPhone and iPad that can combine all your favorite instant messenger clients into one easy to manage place. The new 8.0 version brings with it an updated interface that's been designed with iOS 7 in mind as well as making encrypted messaging free for everyone.
Both the free and paid versions of IM+ were updated to version 8.0. The main differences between the two is that the free version will be ad supported. If you want Skype integration, you'll also need to opt for the premium version.
You can subscribe to IM+'s own SMS replacement service, Beep from within either of the apps as an in-app purchase. Off-the-Record messaging which is encrypted on both ends, has been made free as well for either paid or free users of the IM+ service. There's nothing for you to pay for or configure any longer.
IM+ also support iCloud sync so if you download an IM+ client on another iOS device, there's no need to configure all your accounts again. As long as the device is linked to your iCloud account, all your settings will be transferred over with no effort on your part.
