Already learning toki pona! its great! my only complaint is the hint feature (it spazzes out when you try and type in it, so it doesn't work)
update: completely fixed! this app is amazing, has so many thoughtful features that makes it a smooth experience, and honestly just so refreshing to not have an app loaded full of ads!

Developer Response ,
