A translator app/website for the Tetun language, which now has over 50,000 monthly active users: https://tetun.org
Tetun is the national language in Timor-Leste, and it's not available on Google Translate. Most of my users are Timorese students translating educational content from English to Tetun.
Very possible this stat has increased in the last two months, would be interested to see the trend here
