# I vs MAI

The clearest difference is in-app purchases: I at none against MAI's 3. I also leads on iOS requirement (12.0 vs 17.6). MAI's advantage is ads (none vs shown) and update cadence (weekly vs every 6 months). On price and device support there is nothing between them.

Both are free to download. MAI sells 3 in-app purchases, starting at $12.99 per month. I asks for nothing beyond the download.

I ships an update every 6 months, MAI weekly. The most recent releases landed on October 21, 2026 and October 6, 2026 respectively.
