Verdict
The clearest difference is review sentiment: KnowKnow AI at 100% against Lingo by Abbott's 44%. KnowKnow AI also leads on update cadence (every 3 weeks vs every 2 months). Lingo by Abbott's advantage is rating (4.5 vs 3.0) and in-app purchases (none vs 4). On price, ads, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. KnowKnow AI sells 4 in-app purchases, starting at $9.99 per month. Lingo by Abbott asks for nothing beyond the download.
Lingo by Abbott holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Lingo by Abbott has 7.9K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 44% of Lingo by Abbott's written reviews are positive against 100% of KnowKnow AI's, so the app with the better star average is not the one people write more warmly about.
Lingo by Abbott ships an update every 2 months, KnowKnow AI every 3 weeks. The most recent releases landed on October 19, 2026 and October 3, 2026 respectively.
