# Portable USB · Cloud Ready vs I

The clearest difference is rating: I at 5.0 against Portable USB · Cloud Ready's 4.2. I also leads on in-app purchases (none vs 2) and ads (none vs shown). Portable USB · Cloud Ready's advantage is review sentiment (81% vs 50%) and ratings volume (59 vs 5). On price and device support there is nothing between them.

Both are free to download. Portable USB · Cloud Ready sells 2 one-off in-app purchases. I asks for nothing beyond the download.

I holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Portable USB · Cloud Ready has 59 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 81% of Portable USB · Cloud Ready's written reviews are positive against 50% of I's, so the app with the better star average is not the one people write more warmly about.

Portable USB · Cloud Ready ships an update every 3 months, I every 9 days. The most recent releases landed on September 21, 2026 and June 4, 2026 respectively.
