Paying 100 bucks for an app to use a service that still growing (and in the state Lemmy is currently in) is having so much faith. I really hope Lemmy stays, grows and matures.
That's for Ultra. Pro will be a one time payment available as a separate app on the play store. Pro will be available once sync is out of beta, from what I've heard.
Yeah the $20 one is just to remove ads and is a lifetime purchase. I figured that there would be a "pro" version like sync for reddit but it seems like it's all on the same app now and not separate.
