The crux of the Atkins lifestyle is in accurately and consistently tracking and monitoring carb intake. The database in the back end of this app is a train wreck, as others have mentioned. Without that being thoroughly scrubbed and corrected, this tool is just about useless. The app should also strive to mirror the web version as much as is possible, for example there is no way to track water consumption in the mobile app or to graphically display progress.
