Verdict

The call

The clearest difference is in-app purchases: OBDGO PRO at none against tes's 8. OBDGO PRO also leads on rating (4.5 vs 4.3) and iOS requirement (11.0 vs 17.0). tes's advantage is update cadence (every 3 weeks vs every 2 months). On price, review sentiment, ratings volume and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

OBDGO PRO holds the better App Store score, 4.5 against 4.3. Both are backed by a comparable volume of ratings — 22 and 31 respectively. Written reviews complicate that: 75% of tes's written reviews are positive against 69% of OBDGO PRO's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

tes ships an update every 3 weeks, OBDGO PRO every 2 months. Both last shipped on November 3, 2026.
