Verdict
The clearest difference is rating: Decim8 at 3.8 against Blackie's 3.1. Decim8 also leads on update cadence (weekly vs monthly) and price ($0.99 vs $3.99). On review sentiment, 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
Decim8 costs $0.99 and Blackie $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Decim8 holds the better App Store score, 3.8 against 3.1. Both are backed by a comparable volume of ratings — 149 and 44 respectively. Written reviews complicate that: 52% of Decim8's written reviews are positive against 58% of Blackie's, so the app with the better star average is not the one people write more warmly about.
Decim8 ships an update weekly, Blackie monthly. Both last shipped on September 22, 2026.
