FieldStack is an offline field workspace for construction plan PDFs. Import the drawings without changing the original files, search every page for a room or sheet in seconds, and build a board of just the sheets a task needs. It is built for job sites with bad or no internet. SEARCH EVERY PAGE Type a room number, sheet title, or any word. FieldStack searches every page of every plan and opens the page right at the match. BUILD THE BOARD Pull the sheets a task needs into one board and arrange them your way. The full PDF stays readable. MARK UP THE PLANS Draw on any page. The markup shows on every board with that page, and the eye shows or hides it. RECORD FIELD STATE Place notes and track Open, In Progress, Blocked, or Done work. Boards, checks, and notes stay in a private layer beside the drawings. NOTEBOOKS Place plan pages, photos, shapes, and symbols side by side, and connect them. SIRI, SEARCH, AND WIDGETS Ask Siri to search FieldStack, find sheets from Home Screen search, and open a board, a plan set, or search from a widget. BRING THE PLANS Import source PDFs without changing the originals in Files. FieldStack does not require an account, a team workspace, or a subscription. Optional tips support continued development and unlock nothing. The reviewed interface supports English, French, Spanish, and Brazilian Portuguese.
