Verdict

The call

The clearest difference is rating: Glooko at 4.7 against t's 3.6. Glooko also leads on ratings volume (9.7K vs 116) and update cadence (monthly vs every 2 months). t's advantage is review sentiment (42% vs 29%) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Glooko holds the better App Store score, 4.7 against 3.6. That said, the two scores are not equally well evidenced: Glooko has 9.7K ratings behind it against 116, so its average is the more settled of the two. Written reviews complicate that: 29% of Glooko's written reviews are positive against 42% of t's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Glooko ships an update monthly, t every 2 months. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
