User Reviews

Love the minimalist design of JSON Master. The ability to switch between tree and code views is seamless. It’s very helpful for verifying data structures quickly. No unnecessary features, just a solid editor that feels native to iOS. If you’re looking for a reliable JSON tool for your iPhone, this is it.

I’ve tried several JSON tools on iOS, but most of them are either cluttered with ads or have a terrible UI. This one is surprisingly clean and intuitive. It makes reading nested structures so much easier on a smaller screen. The tree view is smooth and the overall performance is great even with larger files. Highly recommended for any dev on the go!

As a backend engineer, I often need to quickly check API responses when I'm away from my desk. This app handles complex JSON objects effortlessly. The editor is responsive, and the syntax highlighting is spot on. It has definitely improved my mobile workflow. Simple, fast, and does exactly what it promises. 5 stars!
