Verdict

The call

The clearest difference is price: CrazyStone DeepLearning at Free against Go's $1.99. CrazyStone DeepLearning also leads on update cadence (every 2 months vs every 45 months) and ratings volume (1K vs 1). Go's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Go holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: CrazyStone DeepLearning has 1K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 72% of CrazyStone DeepLearning's written reviews are positive against 63% of Go's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CrazyStone DeepLearning ships an update every 2 months, Go every 45 months. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
