Ratings and reviews

I'd prefer the UI to be conformant to Google's M3 Expressive standard however, the app is great in upscaling photos; I just wish it worked on DNG files. When I tried it, the thumbnail only gets upscaled not the RAW data itself, which I presume to be more high quality because of the data present. Anyway, it basically functions like the Google Pixel 10 Pro's Pro Res Zoom. Cheers to on-device upscaling.

Neat tool to have on device image processing without three cloud. Developer is responsive to feedback. looking forward to progress with this one! Ads could be a little cleaner but otherwise it's free with ads out you can pay for the unlocked version in tiers including full lifetime one-time payment.

Amazing image upscaling app! - Easy to use. - High-quality upscaled images. - Fast processing. - User-friendly interface. Only suggestions: - Add more upscaling models/options. - And sometimes doesn't work properly, needs improvement.
