I did a free trial of this app. It worked super great. And I've tried numerous AI Photo Enhancers (Upscalers). But, with frequent use, they kept introducing modifications that made it harder to use.
First, occasionally, my ability to upscale 3x disappears. And their lesser upscaler option doesn't work well, distorting the image.
Second, they suggest not upscaling hi-res images. I'm OK with that. But, they don't define what hi-res is. If I have a blurry 800 x 1200 image, I want to upscale and sharpen it! But, Revoto will fail and shutdown repeatedly when it doesn't want to upscale something.
Third, I subscribed with "no ads"! When shutdowns occur (which is frequent), the log-on process makes the user navigate through an advertisement (very slow). "No ads" should mean "no ads," period!!
Fourth, when they added functionality recently, they made it even more difficult to navigate to the images that I want to upscale. As mentioned above, there are certain images that they'd prefer not to upscale. But, if you're persistent with the fails, shutdowns and slowness, you can upscale an image and it turns out great.
Overall, Revoto is not what the developers advertise it to be.
