If you want a simple check-in method, Day One’s Publish feature for iOS is a great way to do this.

- Create a new entry. Add text and photo, if desired.
- Tap the Publish icon.
- Tap Foursquare, then choose your nearby “Place.”
- Tap Publish.

A native Foursquare / Swarm check-in is created with your entry text and photo. With Day One and Publish, you’ll be able to preserve this event in your personal journal for the long-term and be able to share it with your friends on Foursquare/Swarm.
