I just saw a bunch of noise about FourSquare’s application on Android. Foursquare is a great location based service which lets you “checkin” to restaurants and other venues, and have that automatically shared with your friends.

My buddy Anand Iyer who just went to work for Windows Mobile gave some new bits he has been working on: a FourSquare client on Windows Mobile. The FourSquare mobile web interface is nice, but it just isn’t rich enough – having the data cached, easy to access is important.

The bits are still somewhat secret (not share yet) but what I think people are missing in this whole iphone app and android app building spree is: YOU WANT RICH APPLICATIONS ON YOUR MOBILE. Web based mobile just doesn’t cut it.

Next time you are building a mobile interface, ask your self: should I go for the masses and create something generic which may only drive 5 minutes of use per user. Or should I go for something specialized which will drive 50 minutes use for 25% of your user base.
