# I vs e

The clearest difference is ads: e at none against I's shown. e also leads on update cadence (every 3 weeks vs every 3 months) and iOS requirement (13.0 vs 15.1). 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.

I ships an update every 3 months, e every 3 weeks. The most recent releases landed on November 4, 2026 and November 8, 2026 respectively.
