Verdict

The call

The clearest difference is review sentiment: Diabetes Tracker Realtime CGM at 64% against LinkBluCon's 21%. Diabetes Tracker Realtime CGM also leads on iOS requirement (13.0 vs 17). LinkBluCon's advantage is in-app purchases (none vs 3) and ratings volume (133 vs 4). On price, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

LinkBluCon holds the better App Store score, 3.2 against 3.0. That said, the two scores are not equally well evidenced: LinkBluCon has 133 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 21% of LinkBluCon's written reviews are positive against 64% of Diabetes Tracker Realtime CGM's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on October 22, 2026 and October 17, 2026 respectively.
