The usual advice applies, if you are really worried consult a lawyer. Many will do 30min - 1hr consultations for free and will enlighten you to the risks about your app specifically.
An LLC will protect you from most liabilities and is probably the easiest way to protect yourself in this case. Worst case scenario they sue the company and get all $0 worth of assets from it (assuming no sales).
Applying for an LLC is fairly simple and straight forward. Most states allow you to create one online for less than $100. It honestly takes less than an hour to set them up. Beware the tax implications of doing so, it's a pass-through entity meaning profits and losses are passed directly to your personal income. This is usually not a big deal and most tax software makes this very simple to document at tax time, just keep a record of all profits and expenses.
This is just from experience so take it with a grain of salt. Hopefully this gets you started with some further research.

But worst case has to assume significant sales, or what's the point of the whole discussion? And are you suggesting the OP doesn't defend in court? Because if not, then legal fees will kill OP. If he doesn't defend, then I guess it is cross your fingers and hope the jury in East Texas holds an Opposite Day that day.
