StackFocus turns your iPhone into a professional macro camera. One tap sweeps focus through your subject, stacks the sharpest pixels from every frame, and exports one tack-sharp photograph — no computer, no cloud, no subscription.
One-time $4.99 · no subscription · no account · your photos never leave your phoneTwo centimetres from your subject, a camera can only hold a sliver thinner than a credit card in focus. Everything in front of it, and everything behind it, melts away. One shot was never going to be enough.
A single shot at 2 cm
The lens sweeps through your subject —
up to 28 focus planes in seconds.
Every frame is re-aligned to the pixel,
even if your hands weren't still.
Only the sharpest pixels survive.
One impossible photograph.
The actual capture flow — sweep · align · stack
One tap drives the lens through your whole subject — 12 to 28 frames, metered to the scene. Macro lock means the lens never jumps mid-stack.
Every frame is re-registered with dense optical flow — pixel by pixel, not just globally. Tripods optional, shaky hands forgiven.
The stack is recomposed at full sensor resolution when you export. Every hair, every facet, every scale — kept.
See exactly what's sharp before you shoot — painted over the live view in amber, tuned for macro's razor-thin planes.
Light, colour and detail on a 16-bit master — non-destructive, re-editable, with your look applied to every stack.
No account. No cloud. No analytics in the app. The entire pipeline — capture to export — runs on your phone.
StackFocus has no servers to send anything to. Your macro work is yours — captured, stacked, edited and exported without a single byte leaving the device.
Free to download and try — your first three exports are full-resolution and watermark-free.
Requires an iPhone whose ultra-wide camera can focus: iPhone 13 Pro and newer Pro models, iPhone 16 / 16 Plus, and the iPhone 17 line. 48 MP capture only where the ultra-wide supports it; other models stack at 12 MP. More
