Hi,
Please take a look at the design of www.safenudies.com. I customized the design according to the theme of our app, which is encryption. The fonts and color combination are also matched to the idea of security and privacy.
Additionally, on a project like this, I would work with one or two other freelancers, who are talented guys, and colleagues of mine at my Engineering College.
I'm US English Level 3 qualified in the top 5% on freelancer.com, and I have no hang-ups about coming up with an easy-to-understand copy.
Here's to good things,
Isuru
Additional: If possible, please comment on our app as well (I value a mobile development professional's opinion).
