I just released Version 1.1 of Read it loud! Premium, my SMS reading app available on Android Market. You can now use profile managers like Llama and others that are able to communicate with other apps via Android intent system to activate and deactivate it automatically.

How to? Just configure your profile manager to send the intent

de.exesmobile.messagereaderpremium.ACTIVATE

to activate it. Or send

de.exesmobile.messagereaderpremium.DEACTIVATE

to – well I think you can guess

Thanks to Joe Kurut who sent me an email with the idea for that feature!
