I need professional app

I want to make apps similar with phone's contact.

I think it will be on mobile apps because its feature and maybe need admin panel to access data (but i don't know, i need your suggestion)

This apps can generate QR code and download it by QR code or in the form of name card

Also can scan QR code

And also can analyse how many user that scan their QR code

User need to sign up to this app

User can

1. Input their personal data

2. Get QR code contain one page about their data

So we need to generate QR code

They can choose between they can copy QR code or download name card with QR code with simple template that we already provide

3. Get friend list

Friend list is auto generate with phone's contact

Like whatsapp or line

So when other user on their phone's contact list use this app, that will be autogenerate

4. User or another user do some action with that data

Connect every data (whatsapp, facebook, linkedin) to specific action (like they can message to whatsapp number or call number or enter linkedin profile) like phone's contact

5. Scan QR code for other account's QR code

After they scan QR code, they can add friend to phone's contact

Because friend list will be auto generate from phone's contact, it will be added to friend list too

6. Add friend

By phone number or email

By QR code

7. Analytics

They can know number of people and data (gender, location, age) of people that show their profile or scan their QR code
