FUTO is the company that also hired Louis Rossman. They also make the Grayjay video app, FUTO Voice (offline voice recognition keyboard, as well as FUTO keyboard), and Circles (a Matrix-based private social media app), and many other cool things.

They have a literal free lunch every Friday and I've been a couple times. Eron the owner seems like your typical tech billionaire. You're definitely right that it seems "too good to be true" but we're in the midst of the worst of times for technology and they just keep doing all the right things.

Most of their stuff is licensed under a FUTO license, often called "source available".

Everything is a paid app, but also if you choose not to pay, as Louis says, "that's between you and your God".
