# DFirstCoder vs OBDeleven

The clearest difference is review sentiment: DFirstCoder at 67% against OBDeleven's 14%. DFirstCoder also leads on rating (4.8 vs 4.4) and iOS requirement (13.0 vs 17.0). OBDeleven's advantage is ratings volume (1.6K vs 5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. DFirstCoder sells 8 in-app purchases, starting at $108.99 per year and OBDeleven sells 13 in-app purchases, starting at $69.99 per year. Whichever you choose, the download price is not the number that matters.

DFirstCoder holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: OBDeleven has 1.6K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 67% of DFirstCoder's written reviews are positive against 14% of OBDeleven's.

DFirstCoder ships an update every 3 weeks, OBDeleven fortnightly. The most recent releases landed on October 7, 2026 and October 20, 2026 respectively.
