Verdict
The clearest difference is review sentiment: ZyNotes at 86% against RegEchse's 50%. ZyNotes also leads on ratings volume (28 vs 1) and update cadence (fortnightly vs every 2 months). RegEchse's advantage is in-app purchases (none vs 3) and rating (5.0 vs 4.7). On price, ads 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. ZyNotes sells 3 in-app purchases, starting at $3.99 per 7 days. RegEchse asks for nothing beyond the download.
RegEchse holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: ZyNotes has 28 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of RegEchse's written reviews are positive against 86% of ZyNotes's, so the app with the better star average is not the one people write more warmly about.
RegEchse ships an update every 2 months, ZyNotes fortnightly. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
