# RainMachine vs ALLIANCE bt

The clearest difference is in-app purchases: ALLIANCE bt at none against RainMachine's 1. ALLIANCE bt also leads on rating (2.1 vs 1.8) and iOS requirement (9.0 vs 12.0). RainMachine's advantage is ratings volume (613 vs 79). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. RainMachine sells 1 in-app purchase, starting at $29.99 per year. ALLIANCE bt asks for nothing beyond the download.

ALLIANCE bt holds the better App Store score, 2.1 against 1.8. That said, the two scores are not equally well evidenced: RainMachine has 613 ratings behind it against 79, so its average is the more settled of the two. Written reviews complicate that: 14% of RainMachine's written reviews are positive against 9% of ALLIANCE bt's, so the app with the better star average is not the one people write more warmly about.

RainMachine ships an update monthly, ALLIANCE bt every 2 months. The most recent releases landed on September 19, 2026 and August 3, 2026 respectively.
