I have been recommended to join up with a company called Appoly to complete my mobile application, would this be a good idea?
If anyone could help me out, I would appreciate that. :)
Absolutely not. That company apparently has not responded to your concerns which is a bad sign. Also such companies are a dime a dozen now.
Find one that you can actually talk to and work on your concerns.
IOW, I see nothing special about Appoly.
PS. You asked about Appoly last month. Asking again reinforces my answer here that they are not to be considered given your posts about them and their apparent non-responses to you.
