No — MarbleMap runs in your web browser today. There is no MarbleMap app on the App Store or Google Play yet.
The web platform is built for desktop. Several screens are wide tables — the comparison matrix, the multi-line demand wizard, the split-award board — so the layout does not reshape itself for a phone screen. That is a deliberate choice; a separate app is planned for mobile.
So our recommendation is plain: open MarbleMap on a computer, or on a wide tablet held in landscape. Nothing to install, download or keep updated — just sign in through the browser. Everything works in full there: opening a demand with New Demand, comparing the sealed bids that come in, My Demands, Marketplace and in-demand messaging.
If you do need to check something urgently from your phone, the pages still load, but you may have to scroll sideways through parts of the tables. The decisions — comparing offers, splitting line items, approving an order — go faster and more safely on a wide screen.
When the mobile app does reach the stores, the download links will appear inside MarbleMap itself. Until then your phone receives no push notifications: sign in through the browser to follow your approval status and offer activity.
