Verdict
The clearest difference is ads: Terminology at none against My Collection's shown. Terminology also leads on ratings volume (1.1K vs 9). My Collection's advantage is rating (5.0 vs 4.7) and update cadence (every 2 weeks vs every 4 weeks). On price, review sentiment, in-app purchases and monetization model 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. Terminology sells 2 in-app purchases, starting at $7.99 per year and My Collection sells 10 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
My Collection holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Terminology has 1.1K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 71% of Terminology's written reviews are positive against 70% of My Collection's, so the app with the better star average is not the one people write more warmly about.
Terminology ships an update every 4 weeks, My Collection every 2 weeks. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
