They just released a major update, but it's not something I would pay a subscription for. I paid the lifetime fee in it's early days, but that doesn't unlock the new updates sadly.
I use Analogue for day to day capture, and NoFusion and Moment apps for things I will want to edit later. All with one-time purchase. I don't mind paying for quality apps, but I do have subscription fatigue now.
There is still a lifetime purchase for the new version, IIRC. I can see it in the App Store IAP section. (Which is so useful! Lets me filter for apps that have a lifetime option at all.)
