Only one will be enabled, if the other one appears it will normally show an exclamation mark. If a DIY closed loop system Nightscout doesn't show any active pill, configuration needs to be fixed so that Nightscout receives all necessary data (patient responsibility).

 ## [Loop](https://loopkit.github.io/loopdocs)
 
-[Loop](https://loopdocs.org) is an iOS app that assists in the many insulin dosing decisions people with diabetes face every day. You enter your own settings for desired correction range, basal schedule, insulin sensitivity factor (ISF), carbohydrate ratio (CR) and the type of insulin you are using.  The glucose predictions, using your settings and meal entries, provide Loop with the information needed to modify insulin delivery to attain a targeted glucose range in the future.
