# Moon Style vs Rainbow data

The clearest difference is in-app purchases: Rainbow data at none against Moon Style's 1. Rainbow data also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 4 months). On price and device support there is nothing between them.

Both are free to download. Moon Style sells 1 one-off in-app purchase. Rainbow data asks for nothing beyond the download.

Moon Style ships an update every 4 months, Rainbow data every 3 weeks. The most recent releases landed on September 9, 2026 and September 10, 2026 respectively.
