# i vs Memorize

The clearest difference is ads: Memorize at none against i's shown. Memorize also leads on rating (4.5 vs 4.2) and device support (4 vs 2). i's advantage is update cadence (every 6 days vs every 3 weeks). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.

Both are free to download. i sells 10 one-off in-app purchases and Memorize sells 5 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Memorize holds the better App Store score, 4.5 against 4.2. Both are backed by a comparable volume of ratings — 10 and 13 respectively. Written reviews complicate that: 43% of i's written reviews are positive against 40% of Memorize's, so the app with the better star average is not the one people write more warmly about.

i ships an update every 6 days, Memorize every 3 weeks. The most recent releases landed on September 22, 2026 and August 12, 2026 respectively.
