Customized Fitness App for iOS and Android

We are a cross-fit gym. We want to build an app that will help us stay connected with our members even outside the gym. We have a whole bunch of features that we plan to implement in the app but for the first phase, we are looking to deliver the following features in the app - \r\n\r\n1. Facebook sign-in and member registration\r\n2. Publish workout related information\r\n3. Enter workout related information \r\n4. View leader boards for the workout\r\n5. Make payments to join as a new member or renew membership.\r\n\r\nWe are building the backend system and will provide an API with which the iOS and Android apps have to be integrated. We will also provide all UI assets, user flow wireframes and high fidelity mock-ups.\r\n\r\nWe are looking for experienced, professional mobile developers who can work well with a remote team and have excellent communication skills.\r\n\r\nPlease provide reference apps that you have worked on - for both iOS and Android.
