Wow! Get this! This one actually works!
You can manually check-in just like the Foursquare/Swarm official app (including adding photo, sharing to Facebok, Twitter).
Auto check-ins work (and no need to have the app running or wifi turned on to do so!).
You can even add photos to your auto check-ins as well as share to Facebook, Twitter, or keep them private.
You can set a radius for your check-in locations, we well as a minimum time that you have to be there before it does auto-check-in to avoid pass throughs and drive-bys.
The app is fast, simple to use, and well designed - no need for a tutorial for this app!
I would definitely recommend this app and urge anyone who does to leave a review to let others know if it works for them. Maybe it will help others find this app before having to try out all the other rubbish ones.
