FieldStack turns large construction plan sets into a focused workspace built for the person holding the phone. Open the complete PDF, pull the sheets you need into one zoomable board, and add checks and notes without changing the original drawings. INFINITE REFERENCE CANVAS • Bring plan pages, images, PDFs, text notes, and editable sketches into one smooth visual workspace. • Arrange and group job context freely, then tap a plan page to reopen the original blueprint. • Pan and zoom around the canvas without changing source documents. BUILD A WORKING BOARD • Select one sheet or a group of related sheets from the full reader. • Arrange the board in one, two, or three columns. • Move between sheets while keeping the larger plan context in view. FIND AND RECORD FIELD CONTEXT • Search rooms, doors, labels, and other plan text. • Add Check or Note items at plan locations. • Track field-facing progress as Open, In Progress, Blocked, or Done. • Review the same saved entries from Board or Today. KEEP THE SOURCE CLEAN FieldStack stores boards, checks, notes, and Reference Boards as a separate private layer. Imported source PDFs are not overwritten or flattened by ordinary field work. The reviewed primary FieldStack interface supports English, French, Spanish, and Brazilian Portuguese. Existing customers choose whether to keep English or follow their iPhone language; new installs use the reviewed iPhone language automatically. FieldStack is designed as a personal field tool. It does not require an account, realtime team workspace, or subscription. Optional consumable tips support continued development and unlock nothing.
