Pros
Pro Automatically switches between SMS and IM
invi automatically detects if you're talking to someone who's on invi, and switches between SMS and IM automatically to accommodate. That way, you get fully-featured chats when you're talking to someone who has invi, but you also get a beautiful, seamless experience when simply sending SMS messages.
Pro Share and consume rich media without leaving the app
The killer feature of invi is the ability to consume media in the app. For example if someone sends you a link to a Youtube video invi automatically turns it into a playable widget.
Not only can you view the media in the app, but you can also discuss the videos, photos etc while they are playing.
Pro Beautiful interface
The apps design has a level of care and detail put into it that is rare on Android apps. The home screen is not only beautiful, but shows useful information such as the last message sent, and the status of the person.
The messaging interface itself is very clean and useful. As well as the conversation history it tells you if the recipient has read your last message, is currently reading the conversation or is replying. This makes conversations in invi very fluid as you always know the status of the recipient.
Pro Makes it easy and fun to share stuff
invi makes sharing easy and fun - great to enrich conversations with stuff like YouTube clips, photos, games, web articles etc.
Pro Uses phone numbers for contacts
Invi uses your contacts phone numbers, not a app specific username or email address. This has pros and cons. On the upside it's very simple to get started as it automatically adds all your contacts who have invi installed, and if you text someone who doesn't have invi it will simply go to their normal inbox. This makes it very easy to integrate invi into your existing workflow.
On the downside you cannot chat to someone if you don't have their number (gchat friends for example).
Pro Certain apps can be used in split screen
