# i vs SL Udisk

The clearest difference is rating: SL Udisk at 4.0 against i's 2.1. SL Udisk also leads on iOS requirement (8.0 vs 11.0). i's advantage is ratings volume (83 vs 2) and review sentiment (10% vs 0%). On price, update cadence, ads and in-app purchases there is nothing between them.

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

SL Udisk holds the better App Store score, 4.0 against 2.1. That said, the two scores are not equally well evidenced: i has 83 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 10% of i's written reviews are positive against 0% of SL Udisk's, so the app with the better star average is not the one people write more warmly about.

i ships an update every 3 months, SL Udisk every 6 weeks. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
