Verdict
The clearest difference is review sentiment: Karos at 74% against Izilo's 23%. Karos also leads on update cadence (fortnightly vs every 5 months) and ratings volume (73 vs 1). Izilo's advantage is rating (5.0 vs 4.5). On price, ads, in-app purchases and monetization model 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.
Izilo holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Karos has 73 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 74% of Karos's written reviews are positive against 23% of Izilo's, so the app with the better star average is not the one people write more warmly about.
Karos ships an update fortnightly, Izilo every 5 months. The most recent releases landed on October 26, 2026 and October 25, 2026 respectively.
