Your iPhone is already a bench microscope.

BenchScope shows a live, magnified view at up to 120 fps, with as little delay as possible, so your hands and the screen stay in sync.

BenchScope showing an M92T36 charge controller at 13×, sharp enough to read the part number, with the zoom rail at the bottom of the screen.

Most magnifier apps lag half a second behind your hands. That's fine for reading labels, and useless when you're holding a hot iron.

Features

Low latency, high frame rate

Up to 120 fps. Stabilization, HDR and other processing that add delay are off by default, and the app shows you the measured frame rate and delay.

The lens panel, showing 3840×2160 at 120 fps in 8-bit, with 120 fps selected and the note “Lowest delay.”

The focus panel set to manual, with a near-to-far slider and focus peaking switched on.

Manual control

Pick the lens, zoom without losing sharpness, tap to focus or lock it, set ISO, shutter and white balance by hand.

A crosshair and circle guide in green, laid over the whole board at 1.8×.

Made for the bench

Rotate and mirror the image to match your hands, lock the screen orientation, add crosshair, circle or grid guides, and use the flash as a work light.

A frozen frame at 13×, marked “Frozen”, with a row of the chip's pins and the M92T36 part number.

Freeze and save

Freeze the image and pinch into it to check for bridges. Save photos and video to your library.

Real work

BenchScope was built while replacing an M92T36 USB-C charge controller (a QFN-40) in a Nintendo Switch Lite.
