CropandGrade

CropandGrade is an iPhone and iPad app that rates photos and crops them with AI. It is made by Dongguan Tuesday Technology Co., Ltd. and sold on the App Store for $2.99. The app scores a set of photos offline to pick out the best shots, and it tests many crop ratios and zoom levels on a single photo to find a better composition. It is aimed at photography enthusiasts and professional photographers.

CropandGrade runs all of its processing on the device. Its AI Rating feature uses a deep-learning aesthetic model to give each photo a score, so a large library can be sorted by score and the top shots picked in seconds. The library can be switched between score order and date order. Photos come from the photo library or can be opened from Files on the home screen.

For cropping, the Crazy-Crop mode in CropandGrade explores multiple ratios and zoom levels on one photo and compares the score before and after each crop. Preset ratios include square, 16:9, 4:3 and a cinematic 65:24. Smart Cropping explores composition from different angles automatically, and a real-time preview shows each adjustment as it is made, so parameters can be tuned until the crop looks right.

CropandGrade is a paid app at $2.99. It requires iOS 16 or iPadOS 16 or later and also supports iPod touch. The interface is available in English, German, Japanese, Korean, Simplified Chinese and Spanish. Family Sharing lets up to six family members use the app from one purchase. The developer states that no data is collected from the app, and photos are processed locally rather than uploaded.
