Speed of Light:
Phillips de Pury & Company have made a bespoke attempt to make the experience of browsing and searching auction catalogues intuitive and extra quick. Easily zoom into high res images, share details by email, and find auction results back to 2006.
Sotheby's app is less user-friendly, and only partly functional in portrait mode. Unlike their website, to view catalogues you must register and confirm your email first. It wins on the convenience front –entire catalogues are downloaded to your device to view offline.
Christie’s app lists dates for auctions in the next year. Only recent catalogues and auction results can be downloaded, but they are easy to navigate. Full contact list for all branches is included as well as a basic guide to buying and selling.
