Build an android or ios app.

I have a vocational training center. I would like to inform people who download the app (will be free for download but users must authenticate themselves by email or phone number) and accept the policy of my organization. Aim is to be infromed for any training program we advertise and any job opportunities that many companies ask us to find employees for them. Also after many people will have the app will be able to fill a preconfigure cv so we do the much for any job opportunities.
