# IB Interview Questions vs 66 Days

The clearest difference is review sentiment: IB Interview Questions at 80% against 66 Days's 50%. 66 Days's advantage is update cadence (every 10 days vs every 2 months) and rating (4.8 vs 4.5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. IB Interview Questions sells 7 in-app purchases, starting at $9.99 per month and 66 Days sells 2 in-app purchases, starting at $15.99 per month. Whichever you choose, the download price is not the number that matters.

66 Days holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: 66 Days has 259 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 80% of IB Interview Questions's written reviews are positive against 50% of 66 Days's, so the app with the better star average is not the one people write more warmly about.

IB Interview Questions ships an update every 2 months, 66 Days every 10 days. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
