# Light GO 19x vs CrazyStone DeepLearning

The clearest difference is rating: CrazyStone DeepLearning at 4.7 against Light GO 19x's 3.7. CrazyStone DeepLearning also leads on ratings volume (1K vs 7). Light GO 19x's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Light GO 19x sells 1 one-off in-app purchase and CrazyStone DeepLearning sells 1 in-app purchase, starting at $2.99 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 3.7. That said, the two scores are not equally well evidenced: CrazyStone DeepLearning has 1K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 75% of Light GO 19x's written reviews are positive against 71% of CrazyStone DeepLearning's, so the app with the better star average is not the one people write more warmly about.

Light GO 19x ships an update every 3 months, CrazyStone DeepLearning every 2 months. The most recent releases landed on October 1, 2026 and October 14, 2026 respectively.
