Perfect

literally everything i wanted and for me personally i thought it was really easy to work. the only thing i was wondering if could be added was colors for the keyboard background or keys. otherwise i love this very much

Great for Conlanging!

It's very customizable and you can have it place different keys for a simple tap or a long press, and you can make it jump to different layouts with a button.

The only thing it’s missing is the ability to choose a custom font to have the keys display as.

Absolutely unreal. The best 4 dollars I've ever used on an iOS app.

I have literally been stranded with just an iPad for nearly two years. (My dog is terrified of keyboard sounds.) In that time, I've written over 250,000 words on a single project on this device, almost entirely in Obsidian. I have made 1,001 Templater, Note Toolbar, and Commander scripts...desperately trying to give myself a working environment that doesn't leave me in posture agony for days. I had looked for an app solution so many times, as when I downloaded and used the IPA Keyboard, I saw that creative keyboard designs were at least possible. And I never found one that seemed even remotely capable of suiting my needs. I wasted so much time javascripting when I could have just had this....

My life is completely and unabashedly more tolerable due to the customizability provided by this app.

I'm building my dream keyboard specifically for markdown use as we speak. Single press triple backticks? Do you know how long it took me to physically type just one on the native keyboard? About 1.5 seconds, FOR ONE KEYSTROKE. (You have to be in Shift mode, then hold down the ' for at least a half second, and then you get your one adorable backtick...)

If you have a place people share their keyboards,mI'll post mine when I'm done.

Thank you sooooooo much, compañero!

YOU WILL BE RECEIVING A THANK YOU ON MY NOVEL'S DEDICATION PAGE, I'M NOT KIDDING!

Worst 4$ ever spent

Extremely buggy, edit one key on caps side and it also changes the lower caps. Same for symbols. No way to make it do what you want. Also no autocorrect or languages.

Very Satisfied

This is everything that i wanted from a keyboard making app! This is perfect for creating keyboards using unconventional unicode symbols, has for sure been worth the cost!

only suggestion is perhaps making switching layouts more smoother, kinda like having the symbols button on the default IOS one, maybe it can be like a secondary caps lock function-wise.
