Readings look too dark or too bright

Meter a grey card or an even wall with Grainmeter and with a meter you trust, then enter the difference in Settings → Calibration. If negatives come out thin, add exposure (+).

Which camera does it use?

The main wide camera on the back of the iPhone. Spot metering covers about 4°.

Where does the reciprocity data come from?

From the film makers: HARMAN/Ilford's published factors and the technical data sheets from Kodak and Fujifilm. When a maker publishes nothing past 1 second, Grainmeter says so instead of guessing.

iPhone Duo

Unfold for the side-by-side meter, split exactly at the fold. Stand it half-folded on a table for long exposures: the image stays above the crease, the readout and timer below it.
