# I vs Elementary Mathematics

The clearest difference is update cadence: Elementary Mathematics at every 5 weeks against I's every 14 months. Elementary Mathematics also leads on device support and iOS requirement (13.0 vs 16.4). On price 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.

I ships an update every 14 months, Elementary Mathematics every 5 weeks. The most recent releases landed on October 18, 2026 and October 13, 2026 respectively.
