Is it correct to say,
there are still a lot of apps there charging for money
is the above sentence correct?
It should start with a capital letter. I think the sentence is OK- the repetition of there makes it sound a bit stilted- can it be changed? Some might prefer you to say people charging for apps, but I think it's OK as it is.
----- Not an ESL teacher -----
There are still a lot of apps remaining charging for money.
There are a lot of apps remaining charging for money.
Lots of apps remain there charging for money.
trying to avoid the repetition of there ?
Depending on the context, you could also change the second there
in your original sentence to something more explicit (the name of the place, etc.)
I think the word app is somewhat of a jargon and should be avoided for
nontechnical audiences. But if your audience is technical, no problem.
Give us some context.
