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.
u holds the better App Store score, 4.3 against 3.7. Both are backed by a comparable volume of ratings — 3 and 4 respectively. Written reviews complicate that: 100% of BLE ToolBox's written reviews are positive against 50% of u's, so the app with the better star average is not the one people write more warmly about.
BLE ToolBox ships an update every 19 months, u every 9 months. The most recent releases landed on October 2, 2026 and September 26, 2026 respectively.
