Up for some good times with your Windows Phone 7-toting friends? Firing up the new We’re In app puts you on the fast track for geolocation-powered fun.

Select friends from your phone’s contacts, let “your peeps” (Microsoft’s words, not mine) know what you’re up for, and let the app know how long you’d like to make your location known. We’re In offers built-in group messaging — which we already knew was coming system-wide in the Windows Phone 7 Mango update — and lets your friends ask questions and post updates (like “stuck in traffic” or “almost there”) right inside the app. When the event expires, location sharing stops automatically. Participants can also tap “leave” at any time to opt out instantly.

We’re In is sort of like an answer to check-in apps like Google Latitude and Foursquare, though it doesn’t yet offer goodies like check-in deals or badges. Of course, with Microsoft’s affinity for Facebook there’s a decent chance that We’re In could add support for Facebook Places and Facebook deals in future versions of the app.

Keen-eyed observers might also detect some similarities between We’re In and another Microsoft app for Windows Phone 7, Lunchbox. Lunchbox, however, is a more 9-to-5 take on things and is geared toward business use — power lunches, spontaneous meetings, and the like.
