# Ultradian vs Obsidian Web Clipper

The clearest difference is rating: Obsidian Web Clipper at 4.3 against Ultradian's 3.3. Obsidian Web Clipper also leads on update cadence (every 9 days vs every 5 months) and ratings volume (105 vs 4). Ultradian's advantage is review sentiment (100% vs 69%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Obsidian Web Clipper holds the better App Store score, 4.3 against 3.3. That said, the two scores are not equally well evidenced: Obsidian Web Clipper has 105 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of Ultradian's written reviews are positive against 69% of Obsidian Web Clipper's, so the app with the better star average is not the one people write more warmly about.

Ultradian ships an update every 5 months, Obsidian Web Clipper every 9 days. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
