Prepare

- AI analysis of the area, with a search plan
Hobby metal detecting
Prepare, search, understand your fields.
Hermaion is with you before, during and after every outing: your fields and permissions, the ground you have really covered, your finds identified, catalogued and on display.
- Free to start
- Works with no signal
- English and French
Why “Hermaion”?A name from Ancient Greece, three ideas that suit us
- The lucky find
What you weren’t quite looking for, turning up at the end of a furrow. To the Greeks, that kind of luck was a gift from the gods.
- Luck on the road
The best surprises come along the way, to those who go out and walk. Every outing is a path: you walk, you come back, you cover the ground step by step.
- A travelling companion
Hermes watched over travellers, traders and unexpected encounters. Hermaion wants to be that companion: it plans the outing, keeps the track and helps you understand what you find.
Walking a field, following a path, and coming across what nobody expected: that is a detectorist’s life. That is Hermaion.

Features
Your whole hobby in one app
On your phone in the field, on your computer at home: the same data, with a layout suited to each screen.
Fields and permissions
Area, access, sectors to avoid, and a written landowner agreement ready to print.
AI area analysis
Old maps, ground survey data, nearby heritage: an interest level and a plan.
Coverage tracking
Your passes on the map, in 2D or in relief, and the areas still to do.
Find identification
One photo, and the AI suggests hypotheses, objects to compare and what is missing to decide.
Showcase and vault
Show off your best pieces and keep the rest private. The findspot is never shown.
A review after every outing
The field split into sectors: what is covered, where your finds are, where to go next.
Beach mode
Count your coins by type: the outing’s total adds itself up.
Badges and titles
Distance, finds, junk removed: every outing levels up your character.
On your computer too
Map and records side by side, finds in a table, spreadsheet export, drag-and-drop photos.
After the outing
Know where to go back, and why
Hermaion compares what the analysis expected with what you dug up, then ranks the sectors still to search.
- Nine sectors per field: the darker, the more it is covered.
- Your finds placed where you made them.
- The AI reassesses the field using your outings.
Your profile
A character in your image, surrounded by their kit
Detector, headphones, spade, pinpointer: build your kit, earn titles, and show your showcase to whoever you like.
- Several detectors, and the one used on each outing.
- Friends you can share your vault with, if you wish.
- Your real name never appears; your area stays approximate.
Your showcase
Looking at your finds and showing them off is half the fun
No more photos lost in your phone’s gallery: your best pieces are displayed like in a pocket museum, ready to be admired.
Photos worthy of a display case
Every photo is enhanced and cut out on the phone, then placed on a studio background: sand, white, black or khaki.
- Title, category, period, material
- Several photos per item, front and back
- Free editing, even with no signal
A tidy collection
A showcase for what you show, a vault for the rest. Everything is sorted and found in a moment.
- Search, sort and table view on a computer
- Vault private or shared with friends
- Export your whole collection
Show off without giving anything away
Your showcase appears on your profile and in the Discover feed, where other members like and comment.
- Findspot never shown
- Depth and detecting data kept private
- Hide your showcase at any time
Responsible detecting
A hobby that respects the land, its owners and our heritage
Hermaion gives no right to detect. The app helps you stay within the rules, and show that you do.
Permission first
Every field asks for its access rights. The permission form can be signed on the phone or printed.
The rules of the place
England and Wales, Scotland, France, the US: the rules shown are those of the country where the field is.
Finds reported
An object of historical interest? The app flags it and prepares the record for your Finds Liaison Officer.
Protected places
A findspot is never published. Sensitive sectors of a field are marked to be left alone.
Community
Learn from others, detect together, lend a hand
Discover
Other members’ showcases, to scroll through, like and comment on.
Help
One photo, one question: the community helps identify your objects.
Group outings
Private, with friends or public, with a shared map.

FAQ
Before you start
Do I need to install anything?
No. Hermaion opens in the browser on your phone or computer. On a phone, you can add it to your home screen to open it like an app. An Android app is on the way.
Does it work with no signal?
Yes. An outing can be started and finished with no signal: track, holes and finds stay on the phone and are sent when you are back online. Maps viewed before you leave stay available.
Does the app give me the right to detect?
No. Hermaion is a tool for organising and remembering. You remain solely responsible: landowner permission, protected sites and your country’s rules, which the app reminds you of but cannot check for you.
Who can see my fields and findspots?
Only you, with one exception: the field of a group outing is visible to the participants you accept. The positions and depths of your finds are never published. In the showcase and the help section, only the photos and the description of the object are visible.
Which countries is the app for?
The app is in English and French. Rules and maps are adapted to the United Kingdom, France and the United States, depending on where the field is.
How do I pay for Pro?
By card, through Stripe: Hermaion never sees your card details. You manage your subscription (card, invoices, cancellation) from the app, under Plans. Cancelling takes effect at the end of the period you paid for.
What happens to my data if I stop?
You can download your data or delete your account at any time from the settings.
