Greedy
Greedy dev, charging for features free in the version they ripped and called their own. Super entitled in their dev replies, maybe if they weren’t I’d consider supporting it anyway lol. Dev is charging you a convenience fee for something that’s free. If you don’t mind that, it technically works. Speed is ok but that’s by no fault of the “magic” since again this is repackaged FOSS. (not to take away from the effort they put into this gui, they did do work). $7 if you want to use any real upscaling model. Worth it perhaps, but in my opinion the M chips just aren’t fast enough to justify charging for it. Edit: I’ve softened my stance a little. I paid the $7 more out of curiosity than anything. It’s still not worth it. The models are good and it does work, speed is…. Fine, unimpressive (m4, but on an air). I wish I had realized that unlike waifu2x proper, there is no interpolation here. Now honestly, that’s more inconvenient than disappointing. Part of why my stance has softened is that getting waifu2x or any upscale (gan models etc) is a pain in the neck on Mac. They’re also highly unstable so, this does get points for so far having been very stable. The lack of rife/interpolation is less of an issue because I’ve not had an issue using interpolation software on Mac like I have video upscalers. Your other options would be software that cost $100 or more typically. So for $7 as a convenience fee? Meh. It’s fine. Slow, but acceptable as I’ve said, but god it is slow (if you know, you know, these scalers are always glacial even on proper GPUs)… but fine. Ram usage is good, description doesn’t lie about it being optimized. I do however think that charging extra to use custom models is still a bit greedy. Why charge? No reason but $$$ Whatever though, dev is allowed to earn their bread too.

I wish more people knew about this app
I've been using this little side branch of upscaling for probably over 7 years now, never used anything else. Everything else follows this nauseating standard/framework of being loaded to the brim with ads, begging the user to enter a subscription model, and yet still gives poor outputs that are usually way over processed or try to do that terrible facial reconstruction. Yet with this app I literally make a one time, few dollar purchase and have full access to every model permanently. It's extremely refreshing to find something that was actually streamlined properly.
