# Yi iot vs 4G Pro

Both are free to download. Yi iot sells 10 in-app purchases, starting at $9.99 per month. 4G Pro asks for nothing beyond the download.

Yi iot ships an update every 2 weeks, 4G Pro every 5 weeks. The most recent releases landed on November 15, 2026 and November 11, 2026 respectively.
