About this app

Design your custom keyboard — no ads, no tracking, full control of every key.

• No permissions, no ads, zero data collection
• Keyboard for Android phones, tablets and Wear OS smartwatches
• 40+ languages with word lists and auto-correction
• Free base package · pro packages (EDP, EKP) optional via in-app purchase
• EDP for example Multi-press and multiple functions per key
• EKP for example Code Block Editor for developers

More than just colours:
The Keyboard Designer is a complete keyboard that works in every app. Unlike other keyboards, you don't just tweak colours — you build the whole keyboard: arrange keys freely, set sizes, choose labels, assign any function to any key. No other keyboard offers this kind of control.

Privacy guaranteed:
The app requests no permissions whatsoever — not even internet access. That makes it technically impossible for anything you type to leave your device. Passwords, private messages, contact info stay where they belong: with you.

What a good keyboard must deliver:

1. No internet connection
You enter very private data through a keyboard. A keyboard must therefore not request internet permission — only then can your input be guaranteed to stay on your device.

2. Individual adjustments
The keyboard is the most-used app on a mobile device. It must fit the user perfectly — key arrangement, size, labels, colours, functions. With Keyboard Designer you decide every detail.

3. Easy to use
Limited screen space makes typing hard. Helpers like the enlarged edit bar, big keys and smart actions keep the keyboard usable in tough conditions — walking, one-handed, for people with motor impairments.

4. Speed
A keyboard must respond instantly. This app does not use the system keyboard API but renders all keys as optimised graphics. Input is noticeably faster.

Highlights of recent versions:
• Multi-press: assign multiple functions to a single key, picked by how often you press it
• Auto-correction with bigram context for whole sentences, not just single words
• Code Block Editor with syntax highlighting for developers
• Stickures: hand-drawn symbols as input gestures
• Hardware keyboard mode for Bluetooth and USB keyboards

Packages:
• Base (free): full keyboard, create your own designs, up to 4 rows, 12 keys per row
• Extended Design Package (in-app purchase): unlimited rows and keys, design import/export, rounded keys, colour gradients
• Extended Keyboard Package (in-app purchase): advanced function types like code editor, hardware keyboard support

Note: When you select the keyboard, Android shows a default notice that keyboards can collect data. This notice appears even for keyboards without internet permission — and Keyboard Designer has none.

Ratings and reviews

I use the Clipboard lot on any keyboard, when copying a large amount of text, only getting a potion of it copied is frustrating and time consuming, While this app does have a clip board function, it is sub par to the rest of the great features. Being able to adjust how much text is copied, or removing the limit all together, would be a major improvement, that lack of functionality is the only reason i didn't give 5 stars

It's a really good app for designing custom keyboards! The only problem I have is with whenever my keyboard tries to be in capital mode, where it occasionally disappears, and when I switch back to lowercase, it says that an error has occured. Also, whenever it does this, the app itself only shows the keyboard, tab buttons and changelog button and whenever I try to click the middle part where everything else usually is, the app closes. If this didn't happen, I'd rate it 5 stars.

Excellent app! I've never found one that lets you design a keyboard this thoroughly with this much freedom before. It's a bit tricky at first while you figure it out, but it's more than helpful enough to make up for it, and they do have tutorials and templates! 10/10, would definitely recommend especially if you're looking to remap/adjust keys. I type a lot faster with this.
