Just discovered it some days ago . Really small in size (under 3 mb ) , minimalistic and easy to use client with most of the features your ever gonna need . It started as a fork of fair mail that didn't put features behind a paywall but it tries to be more minimalist and peaceful and have no bloat or flashy colors as fairmail . And most important of all doesn't need webview to function lol that was the biggest plus for me and all of this under 3mb lol . All around a pretty good client .
