Productivity Mobile App Creation

I want a hybrid app created in a way that the app will be for the people who have speaking difficulty. The app will have the following functionality

1. The user will download the app and the other user will also have the app downloaded on their phone. 2. If the other user does not have the app downloaded then the user one can send them an invite to download the app (just like ZOOM for example)

.3. Once both of them have the app downloaded, they can initiate the call with each other.4. as the user 1 has difficulty in speaking, he will be able to type something on the screen and send it so the user 2 can play it an answer it on the phone5. In this app, we can create one simple screen where the user will be able to call the other person and on the bottom section type something and send it. The other user will immediately receive it on his app and will be able to play it instead of reading it. either he can play it or read it so he can listen to what the other user has written.

so we need audio to speak converted on the other user end.The app needs to be done on both platforms Apple and android. Any hybrid platform will work.

More details below

overall functionality will be like
User will log in.
In the screen we provided, there is a logo, and there will be a username-password screen in between. New sign-up can be done or login of the existing user can be done.

In Signup, there will be name, email address,
Phone number, password, confirm password , and there will be captcha and then we can submit it and everything will be saved in the database

Then we can use those credentials and login and go inside

The first screen will be of recent conversations, recent calls will be shown there. UI will be the same as recent calls

2nd, there will be an icon of invite, after clicking that, we can Invite people to download the app

After downloading that app, both users can call each other through the application

3rd tab will be keypad, by clicking on it, we can make calls
There will also be an icon of the contact book and by clicking on it, the saved numbers will be shown and we can take any number from them and call them and it will be shown in the recent calls

While the call is ongoing, there should be an option of chatting, by clicking on the chatting button, we can do some texting at same the time when the person is on the call like in Wh atsapp

Call is ongoing and there is some chatting going on, the user gets the message, there will an icon at the bottom which will be a play button, the audio will also be sent with the converted text of the audio with a play button so the other user can play it and listen to the message and if he wants to reply, he can reply it by text
Option or audio option


Also we need to update on daily basis like login is completed, registration is completed with a video everyday so we can share it with client
