# I vs I

The clearest difference is update cadence: I at every 4 days against I's fortnightly. On price, ads, 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 fortnightly, I every 4 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
