Nice-looking app, it easily pairs with my meter, but there's no way in hell I'm paying a subscription for an app, I DON'T RENT SOFTWARE, and there's no way I'm purchasing it for $100 to avoid a subscription. That price is ridiculously expensive. I'm sick of "Software Subscription Models"; it's just a scam to keep you paying forever for a product, and the price to buy the app outright is extremely overpriced and expensive—$100 for a PHONE APP? Hell no.

very cool app. my only wish is that breakfast, lunch and dinner were in the drop down selection like bedtime is. and after you selected one of those, then 2 simple checkboxes for pre or post. right now I'm heading to select after and then type what meal it was in the note field. also, the history chart at the bottom of the home page says no data available although if I tap on it I can see my data in the graph that shows up there???

Great app! Especially if you're between cgm and have to use a regular monitor for a few days. I will still use this app along with the freestyle libre app. This app is easy to understand and doesn't have obnoxious ads. I bought premium for 6 months. I love it!
