How to find an investor for my project?

You need help for 2 things based on your request.

1, you need the app to be downloaded by many people - this can be achieved in 2 ways, paid method through http://welcome.freemyapps.com etc just search google for more. The other way is free but requires efforts and time, a website might be needed including seo marketing.
The first way is very fast but does not retain but the second way is very slow and retain in as much that your app is good.

2, You need investor for your app - i am sorry, i do not know of any.

thank you for your advice

crowd funding is not needed now. I already made the app, now i just need more people download and use.

If you didn't need crowdfunding since the app have been already launched then I think you are having problems on marketing it to attract people do download and use and as been mentioned its mostly Chinese which means you need to post or market on Chinese section on this forum and anywhere which would be a good spot for advertisement.Goodluck
