There are a healthy number of apps/watchfaces in the Rebble app store, some of them rather old. I can’t comment on whether they work. It’s confusing as there are different tech stacks, so some CGMs will only work with certain Pebble watchfaces / apps.
Most of my research was on the Dexcom Share API, hence why there is more content there.
I’ve helped someone set up T1000 CGM watchface, which was released this year in 2026 - it was easy to setup and seems reliable (more reliable than FitBit Versa 4 running Glances, which supports a lot of different CGM interfaces).
I’m pre-diabetic in Scotland, so definitely not on a continuous glucose monitor at present (and hopefully I may avoid for some time to come) but after buying a simple self blood testing device, one thing that I learned is that different countries express the (same) blood glucose level using different units (mmol/litre or mg/decilitre, apparently).
I haven’t even got my new pebble to see if you give an option for units, but as I was oblivious until recently I thought worth flagging that if it isn’t included, it might be a welcome feature in a future update. Sorry if this is redundant because you already had taken it into account - I really can’t wait to get my new watch, so I am reading a lot of posts on here and getting excited!
