Fast, light, always works – Checkie for Foursquare Review

I love Swarm but it is often too memory intensive for my iPhone 5. Every few days, Swarm inexplicably freezes and won't unfreeze. I have to do a clean reinstall every few weeks. Which brings me to Checkie. Checkie is super-light, super-fast, and has never choked or frozen. Admittedly, Checkie doesn't offer all the features Swarm does. But Checkie always works. If Checkie didn't exist, it would have been necessary to invent it. Moreover, if Checkie didn't exist, I might have given up checking in out of frustration. A must-have app for the diehard checkin enthusiast.
