Hi @thinzartheintzaw00x1 , welcome to Thunkable! 
Be sure to check out our posts about How to ask Great Questions v2.0 and our Community Guidelines as you get started.
If you are looking for someone to build an app for you, I would suggest taking a look at our Freelance / Paid Help Opportunities - Community category. Otherwise, you will likely want to share a bit more about specific ideas or things you have tried in Thunkable already.
Thank you!
