# Cambridge Reader vs Kaizen

The clearest difference is ads: Cambridge Reader at none against Kaizen's shown. Cambridge Reader also leads on iOS requirement (11.0 vs 15.0). Kaizen's advantage is update cadence (every 5 days vs every 6 months). On price, in-app purchases and device support there is nothing between them.

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