APIOrbit 27.1 — Meet iPhone Duo!
Sending a request on a phone usually means a trade-off. You build the request, hit send, then flip to the response, then flip back to fix a header. A narrow screen makes every API check a round trip between views.
APIOrbit 27.1 is built for iPhone Duo, and it removes that round trip. Unfold the device and you get the request on one panel and the response on the other. Fold it and the cover screen becomes a quick way to browse your collections. Let's dig in.
Two panels, one workspace
Unfolded, iPhone Duo gives APIOrbit enough room for the same split you know from iPad and Mac. The request builder sits on the left, with its tabs for request details and settings. The response sits on the right: status code, timing, and the JSON tree.
Change a setting, send again, and watch the response update right beside it. Nothing needs to be dismissed or switched back to.

Your response, tree or raw
The response panel keeps the views you already use. The JSON tree lets you expand objects and arrays and shows each value's type. The raw view shows the same payload as numbered, syntax-highlighted JSON. On Duo's wider unfolded screen both have room to breathe next to the request.


Browse on the cover screen
Fold the Duo and APIOrbit adapts to the cover screen. Your Library is right there: pinned requests, then your collections. Expand a collection and you see its requests with their method and last status code, so you can tell at a glance which ones passed and which came back 403.

A layout that fits the screen
Making an app work on a new screen shape is mostly layout, and the details matter:
- Balanced columns — in portrait, the request builder used to take roughly 60% of the width and squeeze the response. It now stops at its ideal width, so the two panels share the space sensibly.
- Both orientations — the layout adapts whether you hold the Duo in portrait or landscape.
- Sidebar on demand — your library opens as an overlay, so the request and response keep their full width until you need to switch requests.
Thank you
This is a big step for APIOrbit on a new kind of device, and we'd love to hear how it feels in your hands. If APIOrbit is useful to you, a rating or review on the App Store helps more than you'd think. More is on the way.
