Verdict
The clearest difference is rating: Yohaku at 5.0 against Brainlock's 4.6. Brainlock's advantage is update cadence (every 2 weeks vs every 2 months) and ratings volume (5 vs 1). On price, ads, in-app purchases and monetization model 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. Brainlock sells 3 in-app purchases, starting at $9.99 per 7 days and Yohaku sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Yohaku holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Brainlock has 5 ratings behind it against 1, so its average is the more settled of the two.
Brainlock ships an update every 2 weeks, Yohaku every 2 months. The most recent releases landed on October 28, 2026 and October 8, 2026 respectively.
