# RiverApp vs NimbusWx

The clearest difference is review sentiment: RiverApp at 79% against NimbusWx's 33%. RiverApp also leads on rating (4.8 vs 1.5) and ratings volume (5.5K vs 2). NimbusWx's advantage is update cadence (every 5 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. RiverApp sells 3 in-app purchases, starting at $0.99 per month and NimbusWx sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

RiverApp holds the better App Store score, 4.8 against 1.5. That said, the two scores are not equally well evidenced: RiverApp has 5.5K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 79% of RiverApp's written reviews are positive against 33% of NimbusWx's.

RiverApp ships an update every 3 weeks, NimbusWx every 5 days. The most recent releases landed on October 17, 2026 and October 12, 2026 respectively.
