 A significant advantage of **AAPS** over commercial systems is that it is possible for followers, using authenticated text (SMS) commands or via an app ([Nightscout](https://nightscout.github.io/) or AAPSClient) to send a wide range of commands back to the **AAPS** system. This is used extensively by parents of kids with type 1 diabetes who use AAPS. It is very useful: for example, in the playground, if you want to pre-bolus for a snack from your own phone, and your child is busy playing. It is possible to monitor the system (_e.g._ Fitbit), send basic commands (_e.g._ Samsung Galaxy watch 4), or even run the entire AAPS system from a high-spec smartwatch (**5**) (_e.g._ LEMFO LEM14). In this last scenario, you don’t need to use a phone to run AAPS. As battery life on watches improves and technology becomes more stable, this last option is likely to become increasingly attractive.
 
 #### 6) **No commercial constraints, due to open application interfaces**
-Beyond the use of an open-source approach, which allows the source code of **AAPS** to be viewed at any time, the general principle of providing open programming interfaces gives other developers the opportunity to contribute new ideas too. **AAPS** is closely integrated with Nightscout. This accelerates development and allows users to add on features to make life with diabetes even more convenient. Good examples for such integrations are [NightScout](https://nightscout.github.io/), [Nightscout Reporter](https://nightscout-reporter.zreptil.de/), [Xdrip+](https://xdrip.readthedocs.io/en/latest/install/usethedoc/), [M5 stack](https://github.com/mlukasek/M5_NightscoutMon/wiki?fbclid=IwAR1pupoCy-2GuXLS7tIO8HRkOC_536YqSxTK7eF0UrKkM1PuucFYRyPFvd0) etc. There is ongoing dialogue between open-source developers and those developing commercial systems. Many of the DIY innovations are gradually adopted by commercial systems, where developments are understandably slower, partly because interfaces between systems from different companies (pumps, apps, sensors _etc_) need to be carefully negotiated and licenced. This can also slow innovations which are convenient for the patient (or a small sub-population of patients, who have a very specific requirement) but do not generate any sizable profit.

 #### 7) **Detailed app interface** 
 With **AAPS** it is easy to keep track of things like: pump insulin levels, cannula age, sensor age, pump battery age, insulin-on-board _etc_. Many actions can be done through the **AAPS** app (priming the pump, disconnecting the pump _etc_.), instead of on the pump itself, which means the pump can stay in your (or your dependant's) pocket or belt.
