Verdict
The clearest difference is ratings volume: Kutu at 58 against MasterKey's 1. MasterKey's advantage is rating (5.0 vs 4.7) and iOS requirement (13.0 vs 15.0). 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. MasterKey sells 2 in-app purchases, starting at $1.99 per month and Kutu sells 4 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
MasterKey holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Kutu has 58 ratings behind it against 1, so its average is the more settled of the two.
