Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
iData holds the better App Store score, 4.8 against 3.0. Both are backed by a comparable volume of ratings — 5 and 2 respectively. Written reviews complicate that: 33% of iData's written reviews are positive against 100% of TDAS mobile's, so the app with the better star average is not the one people write more warmly about.
iData ships an update monthly, TDAS mobile every 2 months. The most recent releases landed on June 8, 2026 and September 9, 2026 respectively.
