App Creation Advice

Hello, I have been learning to program for a little over a year now. I would like to create an app, and I feel overwhelmed with how I should start. I have experience with html, css, c++ , and python. Although, when I started researching I discovered swift and java script are the primary choices for app creation. I would appreciate if any individual who has gone through this process could point me in a starting direction or even offer just a little advice. Thank you for taking the time to read this, and if you respond extra thank you.
