# REVBOX vs RevLab

The clearest difference is ads: REVBOX at none against RevLab's shown. RevLab's advantage is update cadence (weekly vs every 4 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

REVBOX ships an update every 4 months, RevLab weekly. The most recent releases landed on October 28, 2026 and October 29, 2026 respectively.
