Ok - with the additional information, yes you do have a chance, and a good one, of having approval. As long as the perceived functions of use are for native iOS features, then it should be all good.
The best is to try and see what happens. Usually (most times) Apple will let you know where the problem is with the app.
Things to be aware of, based on my experience, are:
1. If you are developing on a contractual basis for a company - make sure they have a DUNS number and account with Apple - even if you manage it for them - or else Apple will tell you a lot about copyright, intellectual property and all those nice things.
2. Make sure that most of your app is functional without needing a login upfront - and if you do need to have a login first - make sure you provide a username and a password to the review team when you submit the app so that they can test it.
3. Don't be shy to leave a message for the review team (on your Apple Account - when you setup the Store Presence for your app). This goes a long way in establishing an introduction to the workings of your app.
4. Make sure all your entitlements (permissions) are in your app and address what they need to.
5. Follow the tutorial on B4i for submitting an app (The one where you are told how to put your app in Airplane Mode etc).
6. Make sure your app works on iPad (Screen Sizes if you do not use anchors etc). The two stores were recently combined and it is now a requirement for your app to work on both. Also check your device under setting for screen - is it zoomed or normal - this changes your designs if you have it on Zoomed.
7. If you submit and you pass the first time - you have done very well !!
I trust that this will help a bit.
Enjoy !!
