How it works

Three steps to a smarter you.

No lectures. No timers. Just a photo, your best guess and a little brain growth.

1

Observe

Use a prepared deck or create your own. Then study detailed photos curated from the wild, close up and from different angles.

2

Guess

Swipe the photo to skip or ID, then test your knowledge by choosing the correct name from look-alikes.

3

Grow

Stats track your progress. Correct answers earn spores to spend in your Fungarium, an interactive collection of species you've mastered.

Play

Exercise your fung-eye.

Build a custom deck or choose one already built. Multiple learning modes keep things fresh. Photos change every round, so you learn the mushroom and not the picture.

⚠️

Don't be a dummy; never eat a fungus based on this app.

shroomIQ is for learning and fun only and must never be used to decide what is safe to eat. Many edible mushrooms have deadly look-alikes, so always get an in-person identification from a qualified local expert.
