Verdict
The clearest difference is in-app purchases: Chet at none against Otonic's 3. Chet also leads on review sentiment (96% vs 67%) and rating (4.8 vs 4.4). Otonic's advantage is update cadence (every 5 days vs every 5 weeks) and iOS requirement (12.0 vs 18.0). On price, ads and device support there is nothing between them.

Chet holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Chet has 2.4K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 96% of Chet's written reviews are positive against 67% of Otonic's.
Chet ships an update every 5 weeks, Otonic every 5 days. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
