RePix vs PixelGen

RePix enlarges your photos with AI — right on your iPhone. Blurry screenshots, old photos, compressed images saved from social media: RePix uses an AI super-resolution model to upscale them 2x or 4x, producing sharp edges and clean detail instead of simply stretching pixels. YOUR PHOTOS NEVER LEAVE YOUR DEVICE All processing happens on your iPhone. Your images are never uploaded to any server. No account or sign-in required. FEATURES - AI upscaling at 2x or 4x - Crop freely or with preset aspect ratios, and rotate - Before/after comparison slider - Save as JPEG or PNG, or share directly to other apps FREE TO USE Enjoy one free 2x enhancement every 24 hours. For more, watch a short ad. OUTPUT SIZE Output is limited to 4096 px on the long edge. 2x works on areas up to 3276 px on the long edge, and 4x on areas up to 1638 px. If an area is too large, crop it to the size shown in the app first.

Hi Apple review team, PixelGen enhances photos on-device. No account or sign-in is required. All features are available without purchases, subscriptions or ads. The main differentiator of PixelGen is it's ability to run entirely on device. On launch, please wait for model preparation to finish. The progress bar shows estimated time remaining; the first launch may take longer. Models are bundled with the app. If a device compatibility warning appears, tap “I understand, but I want to use it anyway” to continue. Review steps: 1. Tap “Try now” on the Welcome screen. 2. Tap “Add photo to enhance” and select a photo. The gallery is empty on a fresh installation. 3. Optionally crop the photo, then tap “Enhance”. Keep the app in the foreground during processing. 4. Tap the result to compare the original and enhanced image. 5. Tap “Save” and allow Photos access. A new copy is saved; the original remains unchanged. High-resolution images require confirmation before further upscaling. For a quicker test, use a small, locally stored photo. Enhancement works offline. Photos are never uploaded by PixelGen. The Welcome comparison is illustrative; actual enhancement uses the selected photo. Settings contains support and legal links. PostHog receives usage and performance analytics, never photos or photo identifiers. Session replay and advertising tracking are disabled.
