Retake - AI Photo Enhancer

Retake positions itself around a simple promise: everything happens on your phone. Instead of shipping your pictures to a remote GPU, the app bundles its super-resolution and face-recovery models into the download, so edits are processed locally and finish fast. That local-first design is the main reason the app advertises itself as privacy-friendly and usable in airplane mode.

Functionally the app covers four areas. Super Resolution enlarges images while rebuilding edge detail, with the developers claiming up to 600% resolution gains. Face Recovery targets the very common problem of a face being cropped out of a group photo at tiny resolution, reconstructing texture up to roughly 3072 x 3072 pixels. The photo enhance mode handles the harder cleanup work — high-ISO noise, low-light brightness and colour, compression artifacts and general softness. Finally, the cartoon portrait feature converts portraits into a range of illustrated styles.

The app is free to download with advertising, and unlimited access to premium features is unlocked through a monthly, yearly or lifetime in-app purchase managed by Apple. Reviews are a mixed but broadly positive picture: reviewers like the results and the offline operation, while some complain about the volume of ads on the free tier and about the in-app photo picker only exposing recent shots rather than the full camera roll.
