Best mobile app I’ve ever used

I generally hate phones and prefer to do everything on desktop, but this works really well and fits the form factor. 10/10 app

Great app for learning!

I originally picked this up to learn Toki Pona, but I've also ended up learning stuff like the NATO Phonetic alphabet, Finnish (vocab), and Minecraft Enchantment Language.
