Verdict

The call

The clearest difference is price: Go Challenger at Free against CrazyStone DeepLearning Pro's $16.99. Go Challenger also leads on rating (4.7 vs 4.3) and update cadence (every 5 weeks vs every 4 months). CrazyStone DeepLearning Pro's advantage is in-app purchases (none vs 5) and ads (none vs shown). On review sentiment and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Go Challenger holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: CrazyStone DeepLearning Pro has 23 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 64% of CrazyStone DeepLearning Pro's written reviews are positive against 58% of Go Challenger's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CrazyStone DeepLearning Pro ships an update every 4 months, Go Challenger every 5 weeks. Both last shipped on September 30, 2026.
