• With clear documentation on how to run the code and api usage;

• Mobile application should follow apple/google design pattern;

• Provide proper unit test;

• Choose either sql or no-sql database to make the data persistence;

• Use git to manage code;

Feel free to use any libraries you would use if this were a real production app, but remember we're interested in your code & the way you solve the problem, not how well you can use a particular library.

We're interested in your method and how you approach the problem just as much as we're interested in the end result.

Here's what you should aim for:

• Good use of some third part library or use your own;

• Solid testing approach;

• Extensible code;

• Where should I send back the result when I'm done?

Fork this repo and send us a pull request when you think you are done. We don't have deadline for the task.

• What if I have question?

Create a new issue in the repo and we will get back to you very quickly.
