Modification to the Design of a Social Networking App

I'm looking for an experienced mobile app development team that can create a social networking app that will have live streaming capabilities.

Key features include:
- Social Networking: User profiles, friend lists, user interactions
- Live Streaming: A platform for users to broadcast live video
- Additional features common to social networking apps

Ideal skills:
- Proficiency in both iOS and Android app development
- Extensive experience with social networking app development
- In-depth understanding of live streaming technology
- Strong UI/UX design skills
- Previous work on similar projects is a plus

I have two applications:

Android and iOS.
- The Android application is built using Java
- The iOS application is built using an older version of Objective-C.
I am looking for a company to redesign the interfaces of both applications.
Each application has at least 7 interfaces. I have the design I want in a Figma file.

Important note: I am particularly interested in the iOS application design more than the Android one. Any company that does not have experience in Objective-C should not contact us.

We have:

The control panel for the live streaming platform
All the API links you need
The old Android and iOS applications for the control panel
The new design file in Figma


We are looking for a company specialized in programming
The work period should be 1 month
The quality of the work should be high
Provide technical support for at least 3 months in case of issues
