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.

Verdict

The call

The clearest difference is review sentiment: Jayson at 81% against Supanator's 33%. Jayson also leads on ratings volume (448 vs 23). Supanator's advantage is rating (4.8 vs 4.5) and iOS requirement (17.5 vs 26.0). On price, update cadence, ads and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Jayson sells 1 one-off in-app purchase and Supanator sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Supanator holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Jayson has 448 ratings behind it against 23, so its average is the more settled of the two. Written reviews complicate that: 81% of Jayson's written reviews are positive against 33% of Supanator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Jayson ships an update every 3 weeks, Supanator every 2 weeks. The most recent releases landed on November 2, 2026 and October 30, 2026 respectively.
