A few months ago I switched from Dexcom G5 to G6. I like G6 with one exception, I now cannot read the numbers on my iPhone without my reading glasses. I believe that the size of the numbers on the G6 App are slightly smaller than those on G5?
Anyway last night I woke and looked at the display by my bed without using my glasses. I misread the numbers. When I realized this later, I found a solution - I installed Dexcom Follow on my iphone and I now run this instead of the main Dexcom App… With this, I get large black numbers that I can easily read without my glasses even across the room.
Hope that this helps someone.
