Boletus: Mushroom Foraging

Boletus is a mushroom foraging journal with a map of your own mushroom spots, GPS route recording and an offline mushroom guide. Save your finds as you walk, keep track of your harvest and remember where to return on your next mushroom hunt.

Build your own mushroom map

Found porcini, chanterelles or birch boletes? Save the location and mushroom count, then add a photo or note. Your finds build a personal record of where you have picked mushrooms, so you can revisit productive spots on future walks. The map grows with the finds you record.

Record your foraging walks

Start a walk and Boletus records your route using GPS, including when your screen is off. Check your time, distance and mushroom count while recording. Each find stays linked to the walk, so you can review the route later and see what you found along the way.

Keep a mushroom journal with photos

Choose the mushroom and enter the count. Add details when they are useful: subtype, condition, size and the type of forest where it grew. Attach photos and notes to remember a patch of chanterelles or a promising clearing. Your frequently selected mushrooms appear first in the quick picker.

See where you gathered the most

Circles on your mushroom map reflect the number of mushrooms you recorded. Switch to the heatmap to see where your harvest was concentrated. Filter finds by mushroom and date range, view past routes and compare your spots using your own records.

Take offline maps into the forest

Download the area you need before heading out. Once downloaded, the map is available without mobile service. GPS route recording and saving finds work without an internet connection too. Prepare your offline map at home and use it throughout your walk.

Browse the offline mushroom guide

Explore 55 species and subtypes with illustrations, common and scientific names, seasonal information, growing environments and lookalikes. The built-in mushroom guide works offline, so you can browse it while you are in the forest.

Look back on your season

Browse walks by month, review photos and follow the sequence of your finds. Track walking time, distance, personal records and your seasonal or all-time results. Export a route as a GPX file to open it in another compatible app.

Keep your records close

Start using Boletus without creating an account. Your walk history, finds and photos are stored on your phone. Save a backup of your data and photos in one file and restore it when needed. English and Russian interfaces are available, with light and dark themes.

Record your first walk and start building your own map of mushroom spots.

Important: Boletus does not identify mushrooms from photos or confirm whether they are safe to eat. The guide does not replace expert identification. Never eat a mushroom unless its identity and edibility are certain.
