Features & Capabilities

Keyboard Designer offers a complete DIY keyboard experience for Android devices including smartphones, smartwatches (Wear OS), and tablets. This extension lets users fully customize their keyboard layout—not just colors but also key positions and functions, enabling rapid text input tailored to individual needs. Users can create new keyboards or import designs, including support for umlauts and all Android characters.

Privacy is prioritized with zero internet connection permissions, ensuring all personal data stays on the device. The keyboard features fast response times, an enlarged edit bar for easy text correction, and specialized accessibility for difficult conditions or users with handicaps. Additional premium features like export/import, rounded keys, and color gradients are available via in-app purchase. Designed and developed in Sauerland, Germany, Keyboard Designer empowers users with complete control over their keyboard experience across multiple devices.

User Reviews

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.

Recent reviews

Amazingly flexible app. Responsive developer. This is the only app I've found that can replace the, now abandoned, MultilingO. A bunch of stuff is even better than that was. Great work!

Almost perfect, though there is no dead key support, and some text fields do not accept some combining diacritical marks, seemingly at random (Firefox has no problem with an underdot but won't accept an acute accent). The latter is, obviously, not a problem with this app, but it is something you should know.
