Verdict
The clearest difference is review sentiment: CrazyStone DeepLearning at 71% against PocketIgo's 13%. CrazyStone DeepLearning also leads on ratings volume (1K vs 1) and update cadence (every 2 months vs every 4 months). PocketIgo's advantage is in-app purchases (none vs 1) and rating (5.0 vs 4.7). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. CrazyStone DeepLearning sells 1 in-app purchase, starting at $2.99 per month. PocketIgo asks for nothing beyond the download.
PocketIgo 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: 71% of CrazyStone DeepLearning's written reviews are positive against 13% of PocketIgo'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, PocketIgo every 4 months. The most recent releases landed on October 14, 2026 and September 28, 2026 respectively.
