So I tested every open source keyboard a while back and was thouroughly disappointed with every solution. (tested for swipe, word prediction/text prediction, language support, "coding" support, size, speed [yes there are slow Keyboards]) Switched back to asop. This keyboard is over a 100MB as well, BUT it's the first keyboard where I get the additional size.

I habe to check if this is "open source enough" for my needs but glancing over the comments it seems to be completly source available at least which is great. If this turns out to be a decent keyboard I only need an open source text to speech solution and I'm golden.

Edit: tried the keyboard and I failed in adding the dictionaries I downloaded. And I failed to find language models for other languages, but the keyboard seems nice at first glance. Have to try it on a low end device to see how it really performs, but I could live with this

Edit2: oof seems a bit heavy. Phone feels warmer and battery usage reported by Android is kinda high. Have to throughly test the different settings and see how it affects battery life

Edit3: so the voice recognition is okish. If you don't say anything and press the circle it hallucinates something and it's a bit annoying that it only prints out the text after you are done talking, but it is usable. Now I need the ability to transcribe voice messages I get using whisper as well :)

Edit4: OK text prediction is really bad right now. I saw a function to learn from my typing behaviour (with the "eats batteries" warning attached), but hopefully it will get better through this
