Building mobile apps used to cost thousands of dollars. You had to hire software programmers for this job. Now the same job can be done by yourself using online app building tools. Follow the step by step guide provided by these tools and you will be able to create your mobile app within a few days. Build your app for free using an online app building tool. Define your goals clearly before you start building the app. What problems are you trying to solve? Outline the issue you want to solve. Think about all the ways the app can help the end-users solve that issue.
Research a lot when planning your app. You do not want to provide a solution already available on the app store. People must feel compelled to use your app. There should be a market for your solution. Create a mock-up with basic screen layouts, navigation features, workflows, wireframes and UI elements. Add properties to the text boxes, drop downs and buttons. Soon you will have your app ready for publishing on the app store.
