Freelance App Deployment / PWA Specialist Needed

Greetings!

I have a companion app for a physical productivity planner that has already been built in Emergent and is functioning.

I am NOT looking for someone to rebuild the app.

My immediate goal is simple:

Customers who purchase my physical planner will scan a QR code in the planner and access the companion app from their phone.

I would like to explore whether the existing app can be deployed as a PWA/web app or through another simple solution that allows customers to access it without requiring me to go through the Apple App Store approval process for the initial launch.

I am looking for someone who can:

Evaluate the existing Emergent app
Determine the simplest way for customers to access it from their phones
Set it up/deploy it if a PWA or similar solution is appropriate
Make sure it works properly on both iPhone and Android
Help with the QR-code access/link setup
Explain any limitations or additional steps I need to know about

Please do not send me a list of programming languages, frameworks, or technical acronyms as your response.

I am not a developer. I need you to explain in plain terms what you recommend, why, what you would need from me, how long it should take, and your price.

If you have experience taking an existing app built with AI/no-code/low-code tools and getting it ready for real users, please mention that specifically.

This is a project-based opportunity, with the possibility of additional work later if the initial project goes well.

Please send me:

A brief explanation of how you would approach this
Examples of similar work you've done
Your estimated timeline
Your project price

Plain terms only, please. I want to understand your solution before I hire you.
