# CrazyStone DeepLearning vs Surround

The clearest difference is monetization model: CrazyStone DeepLearning at free with in-app purchases against Surround's subscription. CrazyStone DeepLearning also leads on rating (4.7 vs 4.4) and ratings volume (1K vs 49). Surround's advantage is ads (none vs shown) and update cadence (fortnightly vs every 2 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. CrazyStone DeepLearning sells 1 in-app purchase, starting at $2.99 per month and Surround sells 4 in-app purchases, starting at $0.49 per month. Whichever you choose, the download price is not the number that matters.

CrazyStone DeepLearning holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: CrazyStone DeepLearning has 1K ratings behind it against 49, so its average is the more settled of the two. Written reviews complicate that: 72% of CrazyStone DeepLearning's written reviews are positive against 83% of Surround's, so the app with the better star average is not the one people write more warmly about.

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