Offline-first project management that syncs seamlessly when connectivity returns.
Remote construction teams suffer from poor internet connectivity at job sites, making cloud-based project management tools unusable.
BuildVault is a progressive web app (PWA) that allows construction teams to manage tasks, log progress, and upload photos entirely offline using local storage. When internet is available, all data syncs automatically to the cloud dashboard accessible by managers. No more lost updates due to spotty site internet.
