# Underground vs ROX Life

The clearest difference is ads: Underground at none against ROX Life's shown. Underground also leads on monetization model (free vs free with in-app purchases). ROX Life's advantage is update cadence (every 3 weeks vs every 2 months) and iOS requirement (14.0 vs 16.6). On price, review sentiment, 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.

Underground ships an update every 2 months, ROX Life every 3 weeks. The most recent releases landed on October 7, 2026 and October 2, 2026 respectively.
