# StringMaster vs HEY CLAY®

The clearest difference is price: HEY CLAY® at Free against StringMaster's $14.99. HEY CLAY® also leads on update cadence (fortnightly vs every 3 months) and ratings volume (13K vs 24). StringMaster's advantage is review sentiment (80% vs 58%). On rating, ads, in-app purchases and monetization model there is nothing between them.

HEY CLAY® is free to download; StringMaster costs $14.99 up front. StringMaster sells 2 one-off in-app purchases and HEY CLAY® sells 17 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for StringMaster against 4.6 for HEY CLAY®. That said, the two scores are not equally well evidenced: HEY CLAY® has 13K ratings behind it against 24, so its average is the more settled of the two. Written reviews are what separate them: 80% of StringMaster's written reviews are positive against 58% of HEY CLAY®'s.

StringMaster ships an update every 3 months, HEY CLAY® fortnightly. The most recent releases landed on October 4, 2026 and October 12, 2026 respectively.
