Dual Camera — TwinLens

Two cameras. One shot. And it's actually FREE. TwinLens is a dual camera app that films your face and the scene at the SAME time, then merges them into one clip or photo — Picture-in-Picture, side-by-side or stacked. Front and back, in a single tap, all on your phone. ★ 100% FREE — no ads, no watermark, no sign-up, no subscription. Really. Most other dual camera apps hide the good parts behind ads, watermarks or a paywall. TwinLens doesn't. Every feature, free forever.

Dual camera. Front and back. Picture-in-Picture, side-by-side or stacked. One tap. Zero cloud. Zero cost. COMPATIBILITY Simultaneous front + back capture uses Android's concurrent-camera support, which not every phone exposes to apps. On phones that don't support it, TwinLens takes the two photos one right after the other and merges them automatically (sequential dual photo); only simultaneous video stays unavailable.
