This is a free app, available from the Apple App Store or the Google Play Store. Among other things, it has an augmented reality capability providing a tour of various Commonwealth War Graves Commission sites.
The augmented reality system is initially available for these cemeteries in England, Scotland and Wales — Brookwood Military Cemetery, Cambridge City Cemetery, Cannock Chase War Cemetery, Cardiff (Cathays) Cemetery, Edinburgh (Comely Bank) Cemetery, Harrogate (Stonefall) Cemetery, Manchester Southern Cemetery, Seaford Cemetery, Plymouth Naval Memorial and Tower Hill Memorial. More are to come. For aumented reality to operate you have to be there!
The app, which is not a CWGC product, also provides information on other sites, in Ottawa, the Korean memorial (not CWGC) and Beechwood Cemetery. Below is a short video explaining Memory Anchor, directed more at providers than those seeking information.
