Verdict
The clearest difference is review sentiment: Coduzzle at 100% against Devmaxx's 17%. Coduzzle also leads on rating (5.0 vs 4.3) and monetization model (freemium vs subscription). Devmaxx's advantage is ratings volume (520 vs 1) and device support. On price and in-app purchases there is nothing between them.

Both are free to download. Devmaxx sells 2 in-app purchases, starting at $8.99 per month and Coduzzle sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
Coduzzle holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Devmaxx has 520 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 17% of Devmaxx's written reviews are positive against 100% of Coduzzle's.
