DualFrame — record with both cameras at once

DualFrame records the front and back cameras at the same time into a single video. You capture the thing you are filming and your reaction to it in one take — no editing, no syncing, no stitching afterwards.

Frequently asked questions

Does it really record both cameras simultaneously?

Yes — front and back at once, combined into one video as it happens.

Do I have to edit the two videos together afterwards?

No. That is the point: the result is a single file with both views already in it.

What is it good for?

Reactions, travel clips, unboxings, first-time-trying-something videos, concerts, kids' moments — anything where your face is half the story.

Why record the reaction at all?

Because in most memories the event is only half of what you want back later. The look on your face when it happened is the other half, and it is the part a normal camera never keeps.

Can I choose how the two views are arranged?

The two frames are composed together into one video, so both views stay watchable without any editing work.

Do I need an account?

No account is needed.

Is it hard to use?

No — it works like a normal camera app, except both lenses are live. Press record, live the moment, stop.

Can I share the videos normally?

Yes. The output is a regular video file, so it shares anywhere a normal video does.

Why not just use the phone's camera app?

Stock camera apps record one lens at a time. Switching mid-moment means losing the moment; DualFrame simply refuses to choose.

Where can I use it?

In the browser at dual.bnj.app.
