# I vs TI Studio

The clearest difference is update cadence: TI Studio at every 6 weeks against I's every 4 months. I's advantage is iOS requirement (8.0 vs 15.5). 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, TI Studio every 6 weeks. The most recent releases landed on October 6, 2026 and October 5, 2026 respectively.
