The Log is an app designed to help parents track their baby's potty habits during potty training or elimination communication (EC). By observing your baby's natural timing intervals and keeping track of any signals, you can easily track how often your baby pees or poops during observation time. The app eliminates the need for paper printouts and chicken-scratch logging, allowing you to digitally track your baby's habits with ease. You can also take notes of your baby's signals or other observations by long-pressing the activity button.

The Reports screen allows you to easily see your baby's intervals in graph or written format after a few hours or days of observation time. You can set a potty time alarm based on your baby's actual timing intervals, so your smart phone can remind you throughout the day when to offer a "pottytunity." The app also allows you to track one or more babies, keep the logs separate, and easily re-set the data to start a new observation session any time.

The app was developed by Andrea Olson, author of Go Diaper Free and The Tiny Potty Training Book, who has five children that were all out of diapers by walking. The app also offers free classes on potty training and elimination communication for those who need more guidance. Overall, The Log is a helpful tool for parents who want to become potty pros or improve their potty training skills.
