# CrazyStone DeepLearning Pro vs Go Challenger

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.

Go Challenger is free to download; CrazyStone DeepLearning Pro costs $16.99 up front. Go Challenger sells 5 one-off in-app purchases. CrazyStone DeepLearning Pro asks for nothing beyond the download.

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.

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