# 2G vs I

The clearest difference is update cadence: I at every 3 days against 2G's every 2 months. 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.

2G ships an update every 2 months, I every 3 days. The most recent releases landed on October 14, 2026 and October 5, 2026 respectively.
