📝 About this app
Build your own keyboard!
Touchscreen keyboards don't need to be one-size-fits-all, so let's change that! With Keybuild, you choose the layout, the keys, everything.
Keys can be set up to type whatever you want! Letters, greek letters (ɑ, β, ɣ), maths symbols (π, ∫, ∑), arrows (↑→↓←), or even your favourite emoji can be added and organised depending on your needs.
Create multiple ‘panes’, each containing keys arranged using a stack-based layout, and switch between them with either an automatic menu, or direct links.
Add a small number row to your Qwerty keyboard, or have a try using Azerty or Colemak layouts. Build a keyboard that can keep up with your maths-heavy university course, or specialist profession. Or just make a dashboard for your favourite emoji. Or do all that and more, it's up to you!
This app does its best to supports VoiceOver, and accessibility APIs.
Technical note: This app is 99% SwiftUI, which is as close as you can get while we wait for the ‘SwiftUI Lifecycle’ to come to Custom Keyboard Extensions! SwiftUI powers this app's advanced functionality, as well as some of its more unusual bugs. :)
Disclaimer: This iPad app is available on Apple Silicon Macs, but macOS currently does not support keyboard extensions. Still waiting for that tablet Mac!

★★★★★ Thank you
Thank you for developing this app. I am able to type on iPad with the dvorak left-handed keyboard. I am wondering if this can work with an add on iPad keyboard. Thanks again!…
★★★★★ Really cool app
Keybuild is great. It took me a while to figure out, but now I’ve got a great keyboard. I’m really looking forward to future updates. Worth every penny!…

★☆☆☆☆ This app really needs to have instructions
Couldn’t figure out how to use Unicode to customize a keyboard AT ALL. Would it hurt to put ANYTHING about how to use this app?…
★★☆☆☆ Warning: no autocorrect
I was really excited to find an app that let me customize the size of the keys. I set up my new keyboard and was all ready to go, then started using it and found it doesn’t have autocorrect. It is unusable without it for me.…

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
