The official GroupMe app was just released for Windows Phone not too long ago and while nice, it seems a bit redundant with Mango's groups feature. Still, it's a neat service and was one growing very quickly even though it's just over a year old. For those of you who don't remember, GroupMe's gives you the ability to create a group and then text or conference call that group with one number. What's neat is that you can use your data connection for texting the group, which can save some people money in addition to creating a unique conference call number which anyone in the group could use. Although the deal between Skype and Microsoft has been approved, it's still technically in motion, hence Skype buying GroupMe.
The Windows Phone app was still not feature-complete at the time, but it's still looking promising. What does this mean for Windows Phone users now that Microsoft (via Skype) owns the technology? We'll hope to see that conference call feature perhaps built in as well as the data-messaging system integrated into Mango's Group feature--that is, we expect GroupMe's tech to augment and enhance what's already there. We're okay with that. We can also see Skype getting some group features as well, which could also greatly enhance that service for more robust functionality.
For at least now though, the company and brand will remain separate with integration points coming down the line. Negotiations between Skype and GroupMe started around the same time as Skype and Microsoft, hence the overlap of deals.
