You will have to write an introduction/statement about revealing that I have been working on an app.
This is an app that will have beauty on demand services. Use smart words and phrases, beacuse this is going on the instagram and the facebook of the app.
SHould start something like this: I am excited to share that I have been working on a project with an amazing team the past 4 months on developing an app under the name CECE.”
Make sure this is going to be very formal and very good english.
Let me know if there is anything you need to know about details.
