To be perfectly honest, people can steal your idea.

Case in point, back before we launched our first startup, I went out to a trade-fair asking people their opinion about our conceptual product as if it was something we had already built.

I must have talked to maybe 50+ people that one specific day, but one person in particular was very interested in it and wanted to keep in touch.

A bunch of years later, that guy turns out to have been part of another company, in a similar field, with a bigger network, a bigger budget and an existing infrastructure that matched. Over these past years, they've changed their entire company to align with our startup's little idea and actually managed to capture a significant part of the market by launching simultaneously to us rather than following our lead.

The point is, don't ever assume that your neighbor who is an accountant will steel your mobile app idea.

On the other hand, when you are talking to the CEO of a company that is developing mobile experiences about your awesome idea, then don't be surprised if suddenly that company suddenly does take your idea and execute it better than you ever could have.

When you are trying to gain actual "first mover advantage", there are situations where it's not a good idea to tell your idea.
