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.

Verdict
The clearest difference is rating: Jayson at 4.5 against Rootly's 3.6. Jayson also leads on ratings volume (425 vs 18). Rootly's advantage is in-app purchases (none vs 1) and iOS requirement (17.6 vs 26.0). On price, review sentiment, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Jayson sells 1 one-off in-app purchase. Rootly asks for nothing beyond the download.
Jayson holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: Jayson has 425 ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 81% of Jayson's written reviews are positive against 88% of Rootly's, so the app with the better star average is not the one people write more warmly about.
Jayson ships an update every 3 weeks, Rootly fortnightly. The most recent releases landed on October 13, 2026 and October 12, 2026 respectively.
