What you get
Free — included for everyone
An OpenStreetMap base map with the scheduled monuments and other protected sites from Historic England's National Heritage List drawn straight on it, GPS session tracking so you can see the ground you've covered, and a private find journal with photos and notes — kept on your own phone. You can back up and restore everything to a file to move to a new phone. The core map and the private journal work without paying.
Muld+ — what the subscription unlocks
Bare-earth LiDAR. Shaded-relief from the Environment Agency's free national LiDAR, with an adjustable vertical-exaggeration slider. Strips away trees and buildings to pick out round barrows, ridge and furrow, hollow ways and deserted villages the aerial photo hides.
Historic map layers. Out-of-copyright Ordnance Survey six-inch County Series editions and the GB1900 record of vanished places — the surveys that show where the old farms, mills, chapels and field names actually were.
Permission workflow. Turn your landowner permissions into a pipeline — mark each field prospect, asked, granted or declined, and see your whole territory on the map.
Beach & storm conditions. Muld+ ranks coastal spots by the conditions that may have cut sand away and exposed new ground — so you know where to check after a storm.
Offline map downloads. Cache the layers you care about for areas without signal — useful for woodland edges, the coast and anywhere the mobile signal drops out.
Find & journal export. Export your finds as an illustrated report with photos (open and print in any browser), a spreadsheet (CSV) or GPX — plus GPX export of your session tracks.
The base map, scheduled-monument overlays, GPS sessions and the private find journal all work identically on free and Muld+. Muld+ adds the heavier map data and field tools — LiDAR, the historic maps, the permission workflow, beach conditions, offline tile downloads and find export.
Pricing FAQ
Can I try Muld+ before paying?
Yes — the yearly plan will start with a 7-day free trial. If you cancel during the trial in Google Play or the App Store, you won't be charged. The monthly plan has no trial.
How do I cancel?
On Android: open Google Play → your profile → Payments & subscriptions → Subscriptions → Muld → Cancel. On iPhone: open Settings → tap your name → Subscriptions → Muld → Cancel Subscription. Either way, your Muld+ access stays active until the end of the period you've already paid for.
Why is yearly so much cheaper?
Yearly is £49.99 vs. 12 × £6.99 = £83.88 — a 40% discount. Annual subscribers cost less to support and reduce churn, so it's worth offering a real discount instead of a token one.
Can I get a refund?
Refunds are handled by the store you bought through, not by us. On Android: open the purchase in Google Play and choose Request a refund. On iPhone: request a refund from Apple at reportaproblem.apple.com. We don't process store refunds directly — Google or Apple does.
Will the price change?
We don't plan to raise prices on existing subscribers. If it ever happens, Google Play or the App Store notifies you in advance and you can cancel before the new price takes effect.
Do you store my payment details?
No. Payment is handled entirely by Google Play or the App Store. Muld never sees your card number, billing address or other payment data. See our privacy policy for details.
