Leaf Color Scan
Leaf colour against a calibration card; a leaf is compared only with itself over time.
Free (Free and Pro) Needs a camera (easier from a phone)
Also called
leaf colour · yellowing · chlorosis · calibration card
Where it is
- Bottom menu → “Tent” → “🔬 GrowScope Lab” button → “Leaf Color Scan”
The mobile and desktop versions are the same: the app runs at growscope.uk/app/ as a single column with a bottom menu of four tabs — “Today”, “Plants”, “Tent”, “Comparison”. Settings open from the avatar at the top right; the Archive opens from “Comparison”. On a computer the only difference is that features needing the phone’s camera, motion sensor or Bluetooth should be run from a phone.
Requirements
- Camera
- Calibration card (printed from the app)
How to use it
- Print the card following the in-app guide.
- Put the leaf next to the card and shoot.
- Save the measurement.
Result
A leaf colour score and its trend for the plant.
If you can’t see it
- No camera — open on a phone.
