# Dropbox vs Rainbow

The clearest difference is rating: Dropbox at 4.8 against Rainbow's 3.6. Dropbox also leads on review sentiment (48% vs 20%) and update cadence (every 2 weeks vs every 2 months). Rainbow's advantage is iOS requirement (11.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Dropbox sells 9 in-app purchases, starting at $6.99 per month and Rainbow sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Dropbox holds the better App Store score, 4.8 against 3.6. That said, the two scores are not equally well evidenced: Dropbox has 907K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 48% of Dropbox's written reviews are positive against 20% of Rainbow's.

Dropbox ships an update every 2 weeks, Rainbow every 2 months. The most recent releases landed on September 26, 2026 and September 2, 2026 respectively.
