AppGyver Steroids mobile application

We have developed a mobile app using AppGyver Steroids (created in Composer and then exported for Steroids). We are using Parse as the database and the basic functionality is working ok with the data pulling through ok. This is what we require to complete it: - Ability for calculations to be made in JavaScript from within the app. E.g. user enters a number and it calculates the result based on the variable in the page. - The user needs to be able to click an 'Email results' button that will then send the calculation results on the page to someone. - The login page does not validate with the database currently. People should only have to login once also. Please only bid if you have experience in hybrid apps using AppGyver/Steroids and if you can complete this by Sunday.
