Verdict

The call

The clearest difference is in-app purchases: OBDGO PRO at none against DFirstCoder's 8. OBDGO PRO also leads on ratings volume (25 vs 5) and iOS requirement (11.0 vs 13.0). DFirstCoder's advantage is update cadence (every 3 weeks vs every 2 months). On price, rating, review sentiment and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

DFirstCoder holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: OBDGO PRO has 25 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 69% of OBDGO PRO's written reviews are positive against 67% of DFirstCoder's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

OBDGO PRO ships an update every 2 months, DFirstCoder every 3 weeks. The most recent releases landed on September 30, 2026 and September 21, 2026 respectively.
