Hi All:
Try CheckinReminder at:


Inspired by some friends' complaint about always forgetting to check in, we came up with this neat app to remind foursquare users to check in at any place they visit. To serve this need, we design a smart algorithm to detect when the user stays in a place using smartphone sensors. Our algorithm can intelligently turn on/off GPS and other sensors to maximize user's battery life. We believe many Foursquare users will benefit from our app, especially those who are fighting for mayorships. To refine our algorithm and make our app better serve users' need, we collect some anonymized location information for research use.

How to use:
1. Link CheckinReminder with your Foursquare account. It will run in the background afterwards.
2. If you stayed at a place, and when you are leaving, a notification will pop up. Click the notification to check in the recommended place immediately, or click the 'Search Around' button if you prefer a different place.
3. You can choose the type of alarm in the app.
