Book Print Helper is a local tool for authors, editors, independent publishers, and print preparation workflows. Enter trim size, page count, paper weight, binding method, and print quantity to estimate print sheets, spine thickness, paper usage, and basic costs before contacting a printer. The app requires no login, does not connect to the internet, and does not collect personal data. All projects, parameters, and calculation results stay on your device. It is useful for proof copies, graduation portfolios, small print runs, zines, fan books, and internal document layout planning.
