Verdict
The clearest difference is update cadence: Knife Master at every 5 days against Upblock's every 2 months. Knife Master also leads on iOS requirement (11.0 vs 15.0). Upblock's advantage is rating (4.7 vs 4.5) and ratings volume (10 vs 2). 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. Upblock sells 1 one-off in-app purchase and Knife Master sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Upblock holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Upblock has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Upblock ships an update every 2 months, Knife Master every 5 days. Both last shipped on November 3, 2026.
