# SMART Educator vs IOL Reference

The clearest difference is review sentiment: IOL Reference at 89% against SMART Educator's 0%. IOL Reference also leads on update cadence (weekly vs every 2 months) and ratings volume (15 vs 1). SMART Educator's advantage is rating (5.0 vs 4.7) and iOS requirement (12.0 vs 15.5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

SMART Educator holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: IOL Reference has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of SMART Educator's written reviews are positive against 89% of IOL Reference's, so the app with the better star average is not the one people write more warmly about.

SMART Educator ships an update every 2 months, IOL Reference weekly. The most recent releases landed on June 2, 2026 and July 5, 2026 respectively.
