# FileBox vs U

The clearest difference is in-app purchases: U at none against FileBox's 2. U also leads on ads (none vs shown) and rating (5.0 vs 4.8). FileBox's advantage is ratings volume (14 vs 1). On price, update cadence and device support there is nothing between them.

Both are free to download. FileBox sells 2 in-app purchases, starting at $1.99 per month. U asks for nothing beyond the download.

U holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: FileBox has 14 ratings behind it against 1, so its average is the more settled of the two.

FileBox ships an update every 3 weeks, U fortnightly. The most recent releases landed on September 19, 2026 and September 8, 2026 respectively.
