ReceptionRating · Positive reviews · Number of ratings

Otter Transcribe Voice Notes holds the better App Store score, 4.8 against 3.2. That said, the two scores are not equally well evidenced: Otter Transcribe Voice Notes has 88K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 60% of Impromptu Topic Generator's written reviews are positive against 56% of Otter Transcribe Voice Notes's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Impromptu Topic Generator ships an update every 26 months, Otter Transcribe Voice Notes fortnightly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
