# E vs Cho

The clearest difference is ads: E at none against Cho's shown. E also leads on iOS requirement (12.0 vs 16.1). Cho's advantage is update cadence (every 9 days vs every 5 weeks). 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.

E ships an update every 5 weeks, Cho every 9 days. The most recent releases landed on October 7, 2026 and October 11, 2026 respectively.
