Verdict
The clearest difference is price: OkWhen at Free against ABA Wizard's $14.99. OkWhen also leads on update cadence (fortnightly vs every 3 months) and rating (5.0 vs 4.8). ABA Wizard's advantage is ratings volume (3.9K vs 1) and chart position (#9 vs unranked). On review sentiment, ads, in-app purchases and device support 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
OkWhen is free to download; ABA Wizard costs $14.99 up front. Neither carries in-app purchases, so what you see is what you pay.
OkWhen holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: ABA Wizard has 3.9K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 70% of ABA Wizard's written reviews are positive against 67% of OkWhen's, so the app with the better star average is not the one people write more warmly about.
ABA Wizard ships an update every 3 months, OkWhen fortnightly. The most recent releases landed on October 13, 2026 and October 1, 2026 respectively.
