Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
