Jayson is a JSON viewer and editor for iPhone and iPad. Browse JSON as a structure, edit values, and save your changes back to the file. Whether you're inspecting an API response, checking a config file, or making a quick fix on the go, Jayson turns raw JSON into something you can actually read and change. BROWSE AND EDIT - Open JSON files stored on your device or in iCloud Drive. - Toggle between a structured table view and syntax highlighted text. - Add new values and keys, and save your changes back to the file. - Parse text or the contents of a URL from your clipboard into JSON. - Highlight a key from a child of an array to get a quick overview of your data. TABS, SPLITS, AND WINDOWS - Switch between files, or different objects in a single file, using tabs. - Compare JSON in a single file or across files using multiple splits. - Open multiple windows on the iPad. WORKS WITH SHORTCUTS Jayson integrates with Shortcuts, which comes in handy for debugging API calls, previewing JSON files, and building workflows around JSON. - Pass a response from Get Contents of URL to Jayson to see how it is structured. - Open JSON as a document you keep working on, or as a temporary preview. - Format JSON and hand the result to the next action, using spaces or tabs. FREE, WITH AN OPTIONAL UPGRADE Jayson's core functionality is free. Browsing, editing, saving, splits, Shortcuts, and working with up to two tabs at a time cost nothing. A one-time in-app purchase enables having more than two tabs open at once, switching between light and dark themes, and personalizing the app icon, accent color and type icons. One purchase, no subscription.
Neural Object Detector
This app allows users to detect and classify objects in images using machine learning models. It supports importing custom models and offers adjustable settings for camera resolution and computer vision algorithms. Processed data remains on-device for privacy.
- Object detection with YOLOv3
- Image classification with Resnet50
- Import custom Core ML models
- Adjustable camera and algorithm settings
- CPU-only mode for testing
- On-device processing for privacy

Neural Object Detector was designed to be used by both developers and people who are enthusiastic about Machine Learning, Computer Vision, and Object Detection / Image Classification using the combination of both. Neural Object Detector, by default is bundled with YOLOv3 model, which is a neural network for fast object detection that detects 80 different classes of objects. In addition to that, the app allows the users to import any custom machine learning model designed for object detection or image classification, with a single tap, the downloaded model can be imported via the Files app import window which is available within the app by simply pressing the plus icon on the models view so users do not have to leave the app. The app, based on the model selected, draws a rounded rectangle over the detected objects, the annotated image can be rendered and saved to photos or shared if the user chooses to share it directly from the app. To meet every users needs a handful of settings for computer vision algorithm and camera resolution can be changed. Users have the option to enable CPU only mode, which helps test their models under that specific condition. In addition to Object Detection, Neural also supports Image Classification, by default, Neural is bundled with Resnet50 Image Classification Model. Core ML* models which are a type of "Pipeline" in the format of *.mlmodel is supported by this app for Object Detection. No other model format is supported as of now.

The machine learning aspects are all proceed on device so nothing leaves the device. No cloud services are involved. No private analytics services. If, a user decides to contact app support a handful of data will be complied into a log file and attached to the mail composer, these data include app version, app configuration, device model, battery info, device software version, CPU utilised my the app. If the user decided not share, they can simply delete it and continue with the composing the support mail. No data is that is individually identifiable is collected. https://hariharanm.com/

Verdict
The clearest difference is price: Jayson at Free against Neural Object Detector's $2.99. Jayson also leads on ratings volume (425 vs 4) and update cadence (every 3 weeks vs every 4 months). Neural Object Detector's advantage is rating (5.0 vs 4.5) and in-app purchases (none vs 1). On ads, chart position and device support there is nothing between them.

Jayson is free to download; Neural Object Detector costs $2.99 up front. Jayson sells 1 one-off in-app purchase. Neural Object Detector asks for nothing beyond the download.
Neural Object Detector holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Jayson has 425 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 81% of Jayson's written reviews are positive against 100% of Neural Object Detector's.
Jayson ships an update every 3 weeks, Neural Object Detector every 4 months. The most recent releases landed on October 17, 2026 and October 8, 2026 respectively.
