Ducky is a document-based app that helps you infer models from JSON.

### 5/5 — Great app!

*2023-12-01*

Simple and useful.

### 4/5 — Good but...

*2021-07-22*

This will be worth five stars once the codable output can be searched. I think this is relatively essential functionality.

### 5/5 — Great app, great developer

*2021-06-13*

The app is great and does what it’s advertised to do. I can’t fault any of that. I suggested a new feature and the developer seemed nice, courteous and open to suggestions. This is the kind of thing you don’t get with every app. I hope for this app to expand, but this is a great foundation.
