I’m building a lightweight utility that lets people turn images into PDFs, plain text into images, and text directly into PDF files. The goal is a smooth, three-in-one experience that works identically on iOS and Android without forcing users to create an account or sign in—conversion should happen the moment the file is chosen. Here’s what I need from you: • A clean, modern UI with just enough guidance for first-time users while staying clutter-free for repeat conversions. • Fast, reliable conversion logic for the three core tasks: – Image ➔ PDF – Text ➔ Image (common fonts plus system fonts) – Text ➔ PDF • On-device processing where possible, so users can work offline and keep their data private. • Export options that let users share or save the output through the standard iOS and Android share sheets. • Well-structured, commented source code (Swift/SwiftUI or Kotlin/Jetpack Compose, or a cross-platform framework if you can maintain native fluidity). • A concise hand-off document showing how to update the conversion libraries and publish the builds to both App Store and Google Play. No authentication screens, social logins, or extra sign-up prompts—open the app, convert, and move on. If you’ve built file-handling or document-scanning apps before and can deliver polished binaries plus source within a clear timeline, I’d love to hear how you’d tackle it.
