Simple Checkin for Foursquare is a simple alternative to the foursquare app. It allows you to check in to Foursquare in one tap, and it's completely free. You don't need to pay for the service.

To use this app, you'll need your Foursquare username and password. The app will also ask you for a venue name, which you can choose from a list of places that you've visited.

After that, it'll just take you a few seconds to check in. If you want to add a comment, you can write something in the comment field.

The venue that you've checked in to will be added to your profile, and you can see the venue information in your profile.
