Verdict
The clearest difference is monetization model: BLOCKJOCKS at free with in-app purchases against Master Anesthesia's subscription. Master Anesthesia's advantage is update cadence (every 6 days vs every 4 months) and ratings volume (2K vs 96). On price, rating, review sentiment and ads 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. BLOCKJOCKS sells 2 in-app purchases, starting at $19.99 per month and Master Anesthesia sells 7 in-app purchases, starting at $69.99 per year. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.8 for BLOCKJOCKS against 4.9 for Master Anesthesia. That said, the two scores are not equally well evidenced: Master Anesthesia has 2K ratings behind it against 96, so its average is the more settled of the two. Written reviews are what separate them: 85% of BLOCKJOCKS's written reviews are positive against 79% of Master Anesthesia's.
BLOCKJOCKS ships an update every 4 months, Master Anesthesia every 6 days. The most recent releases landed on September 22, 2026 and September 25, 2026 respectively.
