# ZRefractive vs SMART Educator

The clearest difference is update cadence: SMART Educator at every 2 months against ZRefractive's every 10 months. SMART Educator also leads on iOS requirement (12.0 vs 14.0). ZRefractive's advantage is ratings volume (5 vs 1) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

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

On the App Store both sit at effectively the same score — 5.0 for ZRefractive against 5.0 for SMART Educator. That said, the two scores are not equally well evidenced: ZRefractive has 5 ratings behind it against 1, so its average is the more settled of the two.

ZRefractive ships an update every 10 months, SMART Educator every 2 months. The most recent releases landed on June 10, 2026 and June 2, 2026 respectively.
