Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
You should ask for the app to be tested for basic compliance with Apple's HIG (human interface guidelines) though any experienced coder will know to do that. As it's an online app you need to test reachability, ie: being able to get to the website & not letting the user try and fail. Re: stress testing things are easier with newer devices which have more memory but you need to test for low memory conditions on the likes of the iPhone 3GS which is still fully supported but has less memory than the 4 4s & 5. Re: the testing you need to get a few people to try it out early on as well as your professional tester to get feedback on ease of use & by using ordinary people you will get the app past the 'idiot test', ie: how does Joe Q Public find it to use.
