Verdict
The clearest difference is rating: Lingo by Abbott at 4.5 against MySparkDx's 3.0. Lingo by Abbott also leads on ratings volume (8.7K vs 2) and chart position (#176 vs unranked). MySparkDx's advantage is update cadence (every 2 weeks vs every 2 months). On price, review sentiment, ads and in-app purchases 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. Neither carries in-app purchases, so what you see is what you pay.
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 8.7K 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 50% of MySparkDx'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, MySparkDx every 2 weeks. The most recent releases landed on November 10, 2026 and October 31, 2026 respectively.
