Build a focused mobile utility that converts images and common documents into standards-compliant PDFs^?, merges and reorders pages, supports basic text placement, and validates output before printing or sharing. Process files locally by default, preserve originals outside app-controlled storage, and charge once or per export bundle instead of requiring a recurring subscription.

Mobile phones increasingly serve as scanners and document workstations, while subscription fatigue makes transparent ownership-based pricing more attractive. Repeated complaints across competing PDF^? products indicate that the workflow persists beyond one app or release regression.
