On their website (energydome.com) they claim “75%+” round trip efficiency, so not a bad guess!

I completely agree! I guess there are more people on Lemmy using android than iOS. It’s a bit more in line with the ethos I guess? And Mlem is only iOS.

I used to be android as well, but honestly I won’t ever go back I don’t think. But to each there own

I second that! It’s great. I tried a few different ones at the start, then tried Mlem and never looked back.
