# I vs Kale Smart

The clearest difference is update cadence: I at every 4 months against Kale Smart's every 18 months. I also leads on iOS requirement (8.0 vs 13.0). 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 every 4 months, Kale Smart every 18 months. The most recent releases landed on October 6, 2026 and October 11, 2026 respectively.
