HighNote, aside from being a free Internet Protocol-based messaging app for members, the service (available on the iPhone, iPad, iTouch and Android as of today) is unique in the richness and range of messages you can send and receive.
With HighNote you can share music, video, voice recordings, pictures, maps and pretty much any media that’s fit for a phone.
With over 20 customizable greetings like Check this out, congrats and On Fire as well as the ability to change the alignment, color, style and size of your text, HighNote is probably most appealing to those just starting out in their text messaging careers, especially with its ample supply of emoticons.
Yes the app is very obviously gunning for the teen market like any other social service. It has a comprehensive “Quick Reply” section (giving you options like “Love it”/”Hate it”) as well as a feature called “Pulse,” that from what I can see lets users opt into quizzes like “Music,”"Sports,”"Celebrity Gossip,” and “Fashion” and is more importantly rife with potential for ad targeting.
