Can someone kindly share some helpful tips for me to create a perfect mobile application for the android and iPhone users? My friend has recently started her own online pet store, and since she knew that I have studied mobile app development she asked me to create a simple app for her as well. I have also looked up at the work of some mobile app developer as this is my first live project, but it will be more helpful if anyone could suggest me some great tips to create the application for her. I will be waiting for your responses. Thanks.
