# uDisk vs USB TPMS

The clearest difference is rating: uDisk at 4.3 against USB TPMS's 1.0. uDisk also leads on ads (none vs shown) and ratings volume (233 vs 1). USB TPMS's advantage is in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 2 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. uDisk sells 1 one-off in-app purchase. USB TPMS asks for nothing beyond the download.

uDisk holds the better App Store score, 4.3 against 1.0. That said, the two scores are not equally well evidenced: uDisk has 233 ratings behind it against 1, so its average is the more settled of the two.

uDisk ships an update every 2 months, USB TPMS every 3 weeks. The most recent releases landed on September 17, 2026 and June 24, 2026 respectively.
