It started because I missed BlackBerry keyboard's above-key predictions dearly. That is, suggestions are displayed above individual keys as you type, and you can flick them up to input words. Then came the realisation that I am violently nostalgic for the design languages of the past, when phones were fun – and have been looking for something like that on iOS for ages. Lastly, I realised that everything should be highly customisable and privacy-first because that's nice for me and for everyone.
v1.2 now out with 25+ languages supported. Any Qs on the peculiarities (there are a ton) of building a custom iOS keyboard – feel free to shoot, and any thoughts & feedback.
