# E vs E

The clearest difference is ads: E at none against E's shown. E also leads on iOS requirement (15.0 vs 18.0). E's advantage is update cadence (every 3 weeks vs every 4 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. E sells 4 in-app purchases, starting at $50.00 per year and E sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

E ships an update every 4 months, E every 3 weeks. The most recent releases landed on October 10, 2026 and October 25, 2026 respectively.
