Verdict
The clearest difference is rating: GLOWRIUM at 2.4 against OTKAX's 2.0. GLOWRIUM also leads on ratings volume (35 vs 4). OTKAX's advantage is update cadence (every 3 weeks vs every 2 months). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
GLOWRIUM holds the better App Store score, 2.4 against 2.0. That said, the two scores are not equally well evidenced: GLOWRIUM has 35 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of OTKAX's written reviews are positive against 48% of GLOWRIUM's, so the app with the better star average is not the one people write more warmly about.
OTKAX ships an update every 3 weeks, GLOWRIUM every 2 months. Both last shipped on November 3, 2026.
