# D vs arDef

The clearest difference is review sentiment: D at 44% against arDef's 0%. D also leads on iOS requirement (12.1 vs 14.0). arDef's advantage is rating (4.5 vs 2.8) and monetization model (free with in-app purchases vs subscription). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. D sells 5 in-app purchases, starting at $8.99 per 7 days and arDef sells 1 in-app purchase, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

arDef holds the better App Store score, 4.5 against 2.8. Both are backed by a comparable volume of ratings — 12 and 23 respectively. Written reviews complicate that: 44% of D's written reviews are positive against 0% of arDef's, so the app with the better star average is not the one people write more warmly about.

D ships an update every 3 weeks, arDef every 6 days. The most recent releases landed on September 4, 2026 and August 7, 2026 respectively.
