# I vs DZone

The clearest difference is update cadence: DZone at every 6 weeks against I's every 6 months. I's advantage is iOS requirement (12.0 vs 15.6). 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 6 months, DZone every 6 weeks. The most recent releases landed on September 26, 2026 and October 1, 2026 respectively.
