The app has three menu items at the bottom of the main screen: Check in, Resources, and Profile.
This app provides a mobile version of a daily mini-inventory. You may scroll through the questions and answer them as appropriate. At the end of the questions, you have the option of saving your responses so you have an ongoing record of your responses, by date. Additionally, the app gives you the opportunity to add any upcoming events for the next day or in the near future.
On the Resources tab are links to NA's Meeting Search, the current day's meditation, as well as other options to call your sponsor, read literature, or financially contribute to the NA Fellowship. For the links to work properly, you will need to have internet access.
The last section is to keep track of your own information, including your clean date.
