Verdict
The clearest difference is rating: Notesnook at 4.7 against adoc Studio's 2.0. Notesnook also leads on monetization model (free with in-app purchases vs subscription) and update cadence (weekly vs every 2 months). On price, ads, in-app purchases 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. Notesnook sells 17 in-app purchases, starting at $0.99 per month and adoc Studio sells 3 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.
Notesnook holds the better App Store score, 4.7 against 2.0. That said, the two scores are not equally well evidenced: Notesnook has 653 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 78% of Notesnook's written reviews are positive against 60% of adoc Studio's.
Notesnook ships an update weekly, adoc Studio every 2 months. The most recent releases landed on September 26, 2026 and September 18, 2026 respectively.
