# WBMS vs QR Pro

The clearest difference is in-app purchases: WBMS at none against QR Pro's 1. WBMS also leads on ads (none vs shown). QR Pro's advantage is update cadence (daily vs every 24 months) and iOS requirement (13.0 vs 15.6). On price and device support there is nothing between them.

Both are free to download. QR Pro sells 1 one-off in-app purchase. WBMS asks for nothing beyond the download.

WBMS ships an update every 24 months, QR Pro daily. The most recent releases landed on September 16, 2026 and October 25, 2026 respectively.
