# Microsoft OneDrive vs Rainbow

The clearest difference is rating: Microsoft OneDrive at 4.7 against Rainbow's 3.6. Microsoft OneDrive also leads on update cadence (every 10 days vs every 2 months) and ratings volume (487K vs 5). Rainbow's advantage is iOS requirement (11.0 vs 18.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Microsoft OneDrive sells 8 in-app purchases, starting at $0.99 per month and Rainbow sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Microsoft OneDrive holds the better App Store score, 4.7 against 3.6. That said, the two scores are not equally well evidenced: Microsoft OneDrive has 487K ratings behind it against 5, so its average is the more settled of the two. Written reviews split almost evenly too, at 20% and 20% positive.

Microsoft OneDrive ships an update every 10 days, Rainbow every 2 months. The most recent releases landed on September 26, 2026 and September 2, 2026 respectively.
