Verdict
The clearest difference is in-app purchases: Logseq at none against SiYuan's 2. Logseq also leads on rating (4.4 vs 3.9) and ratings volume (265 vs 30). SiYuan's advantage is update cadence (every 8 days vs every 3 weeks). On price, review sentiment, 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. SiYuan sells 2 one-off in-app purchases. Logseq asks for nothing beyond the download.
Logseq holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: Logseq has 265 ratings behind it against 30, so its average is the more settled of the two. Written reviews complicate that: 67% of SiYuan's written reviews are positive against 59% of Logseq's, so the app with the better star average is not the one people write more warmly about.
SiYuan ships an update every 8 days, Logseq every 3 weeks. Both last shipped on November 3, 2026.
