Verdict

The call

The clearest difference is review sentiment: IIDControl at 67% against iCelsius's 35%. iCelsius's advantage is rating (4.2 vs 3.9) and ratings volume (139 vs 14). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

iCelsius holds the better App Store score, 4.2 against 3.9. That said, the two scores are not equally well evidenced: iCelsius has 139 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 35% of iCelsius's written reviews are positive against 67% of IIDControl'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 every 2 months. The most recent releases landed on August 18, 2026 and June 23, 2026 respectively.
