Verdict
The clearest difference is review sentiment: Perfusion Mind at 100% against Deepstash's 30%. Perfusion Mind also leads on rating (5.0 vs 4.7). Deepstash's advantage is update cadence (every 4 days vs every 2 months) and ratings volume (88K vs 5). 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. Deepstash sells 9 in-app purchases, starting at $12.99 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 4.7. That said, the two scores are not equally well evidenced: Deepstash has 88K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 30% of Deepstash's written reviews are positive against 100% of Perfusion Mind's.
Deepstash ships an update every 4 days, Perfusion Mind every 2 months. The most recent releases landed on November 5, 2026 and October 30, 2026 respectively.
