Tips for accurate results

Worms must not touch or cross each other. Spread them apart before taking the photo.
Keep worms away from the purple glare near the edge of the circle.
Make sure the grid squares are sharp and visible around the worms.
Check the coloured outline on each result. If something that isn't a worm was measured, press Not a worm to leave it out.
