# BIM vs X

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

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

BIM ships an update every 6 months, X every 3 weeks. The most recent releases landed on October 24, 2026 and October 13, 2026 respectively.
