A mushroom hunter's best weapon.

Detailed descriptions. Powerful filters. A map of findings. iCloud sync. And much more.

Identifying the right species has never been easier.

Apart from high-definition photos, each species in the app includes detailed descriptions of appearance, habitat and common lookalikes, making it simple to identify species in the outdoors. If you are still unsure about a finding, you can add it as an unknown species and decide later.

All your findings in one place.

Morels will hide no more if you know their exact place of growth. All findings can be viewed on a map, or as a list. And iCloud synchronisation ensures that your findings will automatically appear on your new device.
