Verdict
The clearest difference is review sentiment: Perfusion Mind at 100% against Noji's 64%. Perfusion Mind also leads on ads (none vs shown) and rating (5.0 vs 4.6). Noji's advantage is ratings volume (14K vs 5) and update cadence (every 8 days vs every 2 months). On price, in-app purchases, monetization model 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
Both are free to download. Noji sells 17 in-app purchases, starting at $4.99 per month and Perfusion Mind sells 5 in-app purchases, starting at $4.00 per month. Whichever you choose, the download price is not the number that matters.
Perfusion Mind holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Noji has 14K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 64% of Noji's written reviews are positive against 100% of Perfusion Mind's.
Noji ships an update every 8 days, Perfusion Mind every 2 months. The most recent releases landed on October 19, 2026 and October 16, 2026 respectively.
