My spouse is also using Loop. It's a huge improvement over just the pump alone. Even just changing basal settings is easier in the app versus the pump device interface, which is no longer required using Loop on iOS with the OrangeLink device.

https://loopkit.github.io/loopdocs/ They have a new web browser build method using TestFlight, which no longer requires an up to date Mac running the latest version of Xcode. The web build mode also enables someone to update the Loop app using only their smartphone. Something which is handy for travel or long periods of time without access to a Mac. It only lasts 90 days instead of the 1 year of the Xcode build, but is easy to rebuild on TestFlight.
