Verdict
Obsidian and AI speaker both sit at 4.5 stars, but that hides the real split: 100% of AI speaker's written reviews are positive against 62% of Obsidian's. AI speaker also leads on iOS requirement (13.0 vs 15.6). Obsidian's advantage is in-app purchases (none vs 3) and ratings volume (2.8K vs 7). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. AI speaker sells 3 one-off in-app purchases. Obsidian asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.5 for Obsidian against 4.6 for AI speaker. That said, the two scores are not equally well evidenced: Obsidian has 2.8K ratings behind it against 7, so its average is the more settled of the two. Written reviews are what separate them: 62% of Obsidian's written reviews are positive against 100% of AI speaker's.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on November 8, 2026 and October 30, 2026 respectively.
