Verdict
The clearest difference is rating: CrazyStone DeepLearning at 4.7 against Tsumego Pro (Go problems)'s 4.5. Tsumego Pro (Go problems)'s advantage is update cadence (every 3 weeks vs every 2 months). On price, review sentiment, ratings volume and ads 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. Tsumego Pro (Go problems) sells 12 one-off in-app purchases 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 4.5. Both are backed by a comparable volume of ratings — 1.8K and 1K respectively. Written reviews complicate that: 74% of Tsumego Pro (Go problems)'s written reviews are positive against 72% of CrazyStone DeepLearning's, so the app with the better star average is not the one people write more warmly about.
Tsumego Pro (Go problems) ships an update every 3 weeks, CrazyStone DeepLearning every 2 months. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
