## Review summary

Reviewers praise Keyboard Designer for its powerful customization and broad Unicode support, making it ideal for creators of constructed languages and users who want complete control over their keyboard. The ad-free experience and a substantial set of features available for free are also highlighted. However, many users report a steep learning curve and a confusing, sometimes overwhelming UI, with particular difficulties adding or removing keys from layouts and finding/using emojis. Several reviews note that advanced features often require paid extensions, and that guidance or in-app help could improve. Overall, it's compelling for power users, less approachable for beginners.

### Pros

- Extensive customization options for keyboard layouts, keys, and fonts.
- Strong Unicode and symbol support, useful for constructed languages.
- Ad-free experience with many features available for free.
- Thoughtful, user-centered design and empathy toward users' typing needs.

### Cons

- UI is confusing and has a steep learning curve; not beginner-friendly.
- Editing layouts (adding/removing keys) and discovering settings is not intuitive.
- Emoji access is limited or missing; emoji list not easily available.
- Many useful features are behind paid extensions or may require extended packages.
