I’ve got an iPhone and am using Shuggah. It works really well. The alarms are great. Better than libre. You just need to do the odd scan to keep your libre graphs joined up. It’s a total game changer for me. Feel like I’ve improved my control massively and it’s showing in my stats. I’ve also got it popping up on my Apple Watch. Great when you are out walking or sitting in a restaurant. You can Google lovemylibre for instructions on how to do that.
I read about it on this website. Another contributor mentioned it in a post. Can’t thank them enough.
