Contacted typewise, asked if I could purchase apk from them (the pro version or whatever) since I don't use GPlay store and they said no.

I've tried FOSS keyboards, but always return to Gboard, my particular needs are: Swype and bilingual suggestions (English and Spanish). There are alternatives for Swype style, but none works good with bilingual language.
