If you currently use multiple applications to talk to the same person, say for example you text, IM and Facebook chat your girlfriend, life is about to get so much easier for you. Disa, a unified messaging app that is currently in the alpha testing stages, is looking to combine all of those services into a single conversational thread.
Simply pair your existing accounts to Disa, then allow the app to filter through everything and neatly pile all of your matching contacts and message threads into a column. For anyone that uses Google Hangouts, the UI will look extremely familiar and should be a breeze to navigate through.
The app is currently available to download through the Play store, but is still lacking some of its real meaty features. For example, users will only be able to set up SMS/MMS and WhatsApp accounts for the time being, as the development team is still working on adding other services such as Hangouts, Facebook IM and others.
