01 / Check

Before the drive, check the forest.

Choose a pin and a date. Read the forest’s suitability, seasonal context and available weather evidence together, before committing to a trip.

A number, with its meaning intact.

88/100 describes long-term forest suitability for the selected pin and date. Historical weather for that date is shown separately. The index is not an 88% chance of finding porcini or a promise that a day is good for a trip.

02 / Area Scan

Where should you look first?

Keep the date fixed. Compare forest cells around your pin, then choose a starting area for your own scouting.

iPhone capture, 26 October 2026 · Area Scan for 10 September 2026 · 5 km ring · General Guidance, Private Radar off.

Compare the forest around you.

In this 5 km example, the typical eligible forest cell scores 89/100 and the strongest pocket 92/100; the pin itself scores 88/100. Use the differences to choose where to scout first.

A planning heatmap, not shared finds.

Lower-to-higher colors show seasonal planning indicators. Here, 100% means every eligible forest cell is rated medium-or-better, not a chance of finding porcini. Departure conditions still need checking.

03 / Time Scan

When is it worth returning?

Keep the place fixed. Compare dates to understand the seasonal window, then recheck weather close to departure.

See each day in the seasonal picture.

For 1–30 September 2026, Time Scan returns one seasonal reference value per day, drawn as a smooth trend on a High, Medium and Low scale. It shows long-term habitat and climate timing, not a daily forecast.

Daily trip readiness stays separate.

This past range ends with “Daily trip conditions are not confirmed”: no day-specific trip assessment was returned for these dates. Seasonal timing helps you plan; recheck conditions close to departure.

Private Radar

Your experience makes it personal.

Keep your porcini places and visits in your own archive. When you enable Private Radar, matching confirmed records add personal seasonal context to your Check, on your iPhone.

One forest pin. One date. Private Radar off and on.

Off · General Guidance

89/100 public seasonal baseline. No private adjustment.

On · Your seasonal reference

97/100 private planning index. A local +8-point adjustment; the public baseline remains 89/100.

33 matching records. Used on this iPhone.

The report identifies 33 observation records that match this place and season. That is the count used in this Check, not the total archive or 33 distinct places.

Actual account example · Check for 10 September 2026, captured 26 October 2026 · Same pin, date and public report within each off/on pair. Private locations and individual records are not shown. This is one personal planning example, not an 8% increase in finding probability, an accuracy claim or a guaranteed uplift. Different records can produce a smaller, zero or negative adjustment.

On-device personalization. Never public model training.

Your records are never published as shared hotspots, and neither they nor their derivatives train the public prediction model. Matching happens locally to enrich your own seasonal planning reference; public readiness and other people’s results stay unchanged.

How Private Radar uses your experience

Pro and your opt-in enable the local overlay. Only eligible, confirmed observations with matching place, date and habitat can contribute; more saved records does not mean they all apply. Turning Private Radar off preserves your archive. Online Check still sends the selected location, date and request parameters to the service. Optional encrypted Vault backup is a separate choice, not public model training.

Porcini Field Guide

Know what to look for.

Plan the forest trip with Boletar. Then explore the structures mycologists describe, the limits of visual comparisons, and where to find qualified help.

Explore the Porcini Field Guide

Before you begin.

Is Boletar only for porcini?

Yes. Boletar focuses on the porcini group, not a catalogue or identifier for every mushroom.

Does a score mean a probability of finding porcini?

Not necessarily. Read the exact indicator label. For example, long-term suitability scored out of 100 is an index, not a certified occurrence probability. No result guarantees a harvest.

What do the heatmap and curve show?

Area Scan compares spatial planning indicators for one date. Time Scan compares dates at one pin. Read the displayed mode, date range, legend and sampling interval; seasonal context is not a daily weather forecast.

Are my places public, or used to train the public model?

No. Private records and their derivatives stay out of public training and do not change other users’ predictions. Private Radar personalization and encrypted backup are separate choices.

Can I start without a history of finds?

Yes. General Guidance does not require personal records. You can begin saving places and visits whenever you are ready.

What does an online scan send?

The selected location, date and relevant request parameters go to the service. That is different from publishing your private notes or sending them into public training.

What happens when Pro expires?

You can still read, record, delete and export your own archive, and the backup file and encrypted Vault stay available. Pro planning tools depend on active access. Manage subscription renewal in your Apple account.

Does it identify mushrooms or grant collecting permission?

No. It does not identify species, confirm edibility, or grant land access or collecting rights. Verify identity and local rules independently. Coverage is limited to selected European forest regions.

How can I get Boletar?

Boletar is preparing its App Store release for iPhone. Join the waitlist and we will email you when it is available to download.

Can the Field Guide tell me what I found?

No. It explains observation and points to scientific and expert resources. It does not identify a specimen or determine whether it is safe to eat. Explore the Porcini Field Guide
