<human>:  How do I build a mobile app?
<bot>: To build a mobile app, you will need to have some knowledge of coding and development. You will also need to decide what type of mobile app you want to create, as well as its design and functionality. Once you have a plan in place, you can start to build the app using a code editor and/or development platform. Then, you'll need to test and debug the app to make sure everything is working correctly before submitting it for review.
