Project description:
"Mobile App Developer Needed (iOS / Android) – Focused Utility App

We are looking for an experienced mobile app developer to build a simple, high-polish utility app for iOS and Android.

This is not a complex platform, not an AI product, and not a large backend system.
It does, however, require excellent mobile fundamentals, OS-level experience, and discipline.

About the App

The app allows users to:
Pre-record a personal voice message
Assign it to specific contacts or groups
Automatically send an instant SMS with a secure audio link when a selected contact calls and the user does not answer

The app:

Does not answer calls
Does not replace voicemail
Uses device-sent SMS (no third-party SMS services)
Has a very strict, locked specification

A full developer specification and UX/UI spec are already complete and must be followed exactly.

What We Are Looking For

You must have:

Proven experience building native iOS and/or Android apps
Experience handling OS-level permissions and background behaviour

- Call state detection
- SMS sending
- Microphone access

Experience shipping apps to the App Store and/or Google Play
Ability to work from a clear specification without improvising
Strong attention to reliability, edge cases, and user trust

This is a precision build, not an experimentation project.

What You Do Not Need

AI / ML experience
Complex backend or scaling experience
Web-only or no-code platform experience
Feature ideation or “product improvement” suggestions

We already know exactly what we want built.

Scope & Expectations

MVP build (polished, review-ready)
Minimal backend (audio storage only)
Clean, calm, user-friendly UI
Strong focus on:

- Correct OS behaviour
- Reliability
- App Store / Play Store compliance


To Apply, Please Include

Links to real mobile apps you have built and shipped

Briefly explain your experience with:
- OS permissions
- Background behaviour
- SMS or call-related features (if any)

Confirm that you are comfortable building strictly to spec
