Verdict

The call

The clearest difference is rating: IRIAM at 4.2 against Theri.App's 3.6. IRIAM also leads on ratings volume (450 vs 28). Theri.App's advantage is in-app purchases (none vs 10) and update cadence (every 4 days vs fortnightly). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. IRIAM sells 10 one-off in-app purchases. Theri.App asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

IRIAM holds the better App Store score, 4.2 against 3.6. That said, the two scores are not equally well evidenced: IRIAM has 450 ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 48% of IRIAM's written reviews are positive against 52% of Theri.App's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

IRIAM ships an update fortnightly, Theri.App every 4 days. The most recent releases landed on November 6, 2026 and November 5, 2026 respectively.
