Verdict
The clearest difference is ads: CaptionAddr at none against Whisper Caption's shown. CaptionAddr also leads on update cadence (every 2 weeks vs every 3 months) and ratings volume (7 vs 1). Whisper Caption's advantage is rating (5.0 vs 4.6) and review sentiment (100% vs 75%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Whisper Caption sells 1 one-off in-app purchase and CaptionAddr sells 1 in-app purchase, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
Whisper Caption holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: CaptionAddr has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Whisper Caption's written reviews are positive against 75% of CaptionAddr's.
Whisper Caption ships an update every 3 months, CaptionAddr every 2 weeks. The most recent releases landed on October 9, 2026 and October 20, 2026 respectively.
