# i vs iUSB Pro

The clearest difference is ratings volume: iUSB Pro at 1.1K against i's 23. i's advantage is update cadence (every 5 weeks vs every 3 months). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

i holds the better App Store score, 2.8 against 2.6. That said, the two scores are not equally well evidenced: iUSB Pro has 1.1K ratings behind it against 23, so its average is the more settled of the two. Written reviews point the same way: 15% of i's written reviews are positive against 14% of iUSB Pro's.

i ships an update every 5 weeks, iUSB Pro every 3 months. The most recent releases landed on September 20, 2026 and September 24, 2026 respectively.
