Read full description

Images Classifier enables you to identify and group images using your iPhone or iPad with custom-trained machine learning models. The app includes a built-in model, FruitsClassifier.mlmodel, which detects 8 different types of fruits using a neural network. Features: • Automatically group images into category folders, accessible via the Files app • Preview grouped images within the app • Set a classification confidence threshold - images below this value are grouped under "Other" • Load and run custom machine learning models from your library • Rename or delete models directly from the library Grouped images are saved in the Files app under: [Images Classifier / Images] To Add a Custom Model: Download a pre-trained .mlmodel file and place it in: [Images Classifier / MLModel] via AirDrop You can also train your own model using tools like CreateML or TensorFlow (models must be converted to .mlmodel format) Custom Model Tips: For example, if your model classifies 5 dog breeds - Husky, Bulldog, Golden Retriever, German Shepherd, and Beagle—it will perform accurately for those. However, classifying an unfamiliar breed like Boxer may result in incorrect predictions (e.g., classified as Bulldog). To improve results, include as many relevant classes as possible when training your model. Usage Examples: • Group plant species images in the jungle using a custom-trained model • Identify and sort dog breeds with a trained model • Classify and group wildlife or insect species • Detect and categorize defective products • And many more use cases - limited only by your creativity Quick Start Guide: 1. AirDrop your .mlmodel file (e.g., DogBreedsModel.mlmodel) into: [Images Classifier / MLModel] via the Files app 2. Launch the Images Classifier app 3. Open the Library tab and select your model (e.g., DogBreedsModel.mlmodel) 4. Load images from your Camera Roll 5. Tap Run and wait for processing to complete 6. Tap Result to view categorized images 7. Access all grouped images in the Files app under: [Images Classifier / Images] [*] Make sure your model is specifically trained for image classification (not object detection or other ML types). What is Image Classification? Image classification is the process of identifying and labeling groups of pixels or vectors within an image using predefined rules. It's a supervised learning task where a model is trained to recognize specific target classes using labeled sample images. Early computer vision models used raw pixel data as input, and this foundation still powers many modern classification techniques.

One photo. More ways to light it. Add soft light to a portrait, find a new mood for a still life, or let light move across your image. Relight makes photo lighting a hands-on creative process: see the effect, refine it, and keep the light you love. START WITH A LOOK Explore 11 lighting looks organized by purpose: essentials, portraits, mood and light patterns. From Softbox, Window and Golden to Duotone, Blinds and Neon, find a starting point for your photo. Every look can be refined. MAKE EVERY LIGHT YOUR OWN Move light points directly on your photo. Adjust brightness, color, reach and distance. Combine up to four lights with ambient illumination. Hold to see the original; release to return to your edit. STILL PHOTO. MOVING LIGHT. Explore 5 film styles, from a gradual reveal to alternating lights and moving window light. Adjust the movement, then preview and export a four- or six-second looping light film. Light changes the atmosphere; it does not animate the subject into new actions. KEEP THE DETAILS Crop and rotate before editing. Zoom in to inspect your result. Keep saved photos and films in your library, ready to view and share. High-resolution photo export reaches up to 4096 pixels on the long edge, limited by your source image, without upscaling. YOUR PHOTOS STAY YOURS No account required. Photo processing happens on your device without uploading your images or buying generation credits. Made for iPhone and iPad, in English and Simplified Chinese. START FREE. UNLOCK ONCE. Use Softbox and single-light editing for free, with photo exports up to 1200 pixels on the long edge. Preview other looks, multiple lights and films before a one-time purchase unlocks their export. The features included in this purchase require no renewal or per-use fees. Previous paid-app customers can restore complete Studio access without buying again. Start with a sharp, evenly lit portrait or still life. Results depend on the lighting and detail in your source photo. Relight cannot recover hidden detail or fully remove strong shadows already in an image.
