Verdict
The clearest difference is review sentiment: xBluetooth at 73% against TDEE's 36%. xBluetooth also leads on in-app purchases (none vs 1) and iOS requirement (12.0 vs 17.2). TDEE's advantage is rating (4.7 vs 4.2) and update cadence (every 4 weeks vs every 21 months). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. TDEE sells 1 one-off in-app purchase. xBluetooth asks for nothing beyond the download.
TDEE holds the better App Store score, 4.7 against 4.2. Both are backed by a comparable volume of ratings — 482 and 366 respectively. Written reviews complicate that: 36% of TDEE's written reviews are positive against 73% of xBluetooth's, so the app with the better star average is not the one people write more warmly about.
TDEE ships an update every 4 weeks, xBluetooth every 21 months. The most recent releases landed on September 18, 2026 and September 25, 2026 respectively.
