Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
iDiskk Pro holds the better App Store score, 2.5 against 2.3. That said, the two scores are not equally well evidenced: iDiskk Pro has 321 ratings behind it against 32, so its average is the more settled of the two. Written reviews complicate that: 21% of iExpand's written reviews are positive against 14% of iDiskk Pro's, so the app with the better star average is not the one people write more warmly about.
iExpand ships an update every 3 months, iDiskk Pro every 2 months. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
