Hello!
I'm a representative of a young developing company in medical cosmetology. We want to launch an application + website. We have already found a developer and designer for the site. Now we are looking for a team to develop the application. The primary purpose of the application: is to show the user the benefits of using our cosmetics. The application should perform mathematical functions (some formulas we will provide, some will have to be invented). It has to have a modern design with graphs, charts, input and output fields. The application should be intuitive and work on devices based on IOS, Android, Windows, Mac 

Developers were looking for on the freelance exchanges and through google search, but so far no one came up. Maybe you know someone who can take on the development of the application?
