"How can I protect my idea from being stolen by a development company ?"

Our NDA's, in fact, are bi-directional ... meaning that we are also protected so we can openly throw ideas out there based on our extensive experience and know that those ideas are safe too.
All of our employees are also covered by Confidentiality Agreements with us - and this protection extends via the NDA to you.
Unlike some of the "top" iPad/iPhone Developers in Australia (Yeah - you know who you are!), we don't outsource overseas, so we have much tighter legal control over Intellectual Property (IP) that comes through our hands.
If your development company doesn't immediately offer an NDA, BEWARE! We have all heard stories of ideas suddenly turning up elsewhere after seemingly innocent discussions.
Don't let that happen to your next big idea.
