Users report that while the keyboard offers aesthetic customization and number shortcuts, the lack of predictive text and auto-correct makes it inefficient for heavy daily messaging. ### Can I turn off the keyboard sounds? According to user reviews, the current version does not provide an option to mute the persistent key stroke sounds. ### What is the main difference between this and the default iOS keyboard? This app provides custom themes, key shapes, and a number-row shortcut feature, but lacks the native auto-correct and predictive text capabilities of the default iOS keyboard. ### Is there a free alternative with auto-correct? Many third-party keyboard apps on the App Store offer both custom themes and native-like predictive text, which may be better alternatives for users who require auto-correct functionality. ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** - Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** - Identifies the app's core features, monetization model, target audience, and competitive positioning.
