Parents and teenagers who are struggling to make the other side see their part of argument during a family fight may find tips right on their smartphones that could lead to a compromise instead of continuing the fight.
The 'Close My Deal' app gives parents useful hints on how to approach their children and gives teenagers suggestions on how to negotiate.
AdvertisementIt works by posing scenarios, which could spark an argument, and prompts the user to choose from a range of answers to the problem.
It then scores users on their choice and gives tips on how to improve their negotiating style.
Both sides can also get ideas for "concessions" they can make to secure a deal, for example the teenager offering to unload the dishwasher every night or go without pocket money for a month, or parents agreeing to pay for concert tickets if a teenager attends an elderly relative's birthday party.
"In my experience, negotiating with a stubborn teenager is every bit as difficult as trying to win a boardroom deal," the Daily Mail quoted creator Clive Rich, 52, a business negotiator as saying.
As part of the app, users can choose from a range of answers before being scored and then get feedback on how to tackle each situation and improve their negotiation style.
The web app also gives users an insight into their personal "negotiating style."
By completing the profiler section users can find out if they subconsciously use demanding or aggressive behaviour during negotiations and receive instructions on how to adapt their approach.
After a 25-year career brokering multi-billion corporate deals Rich now hopes his new app - launched this week - will eventually bring an end to the family squabbles.
Rich, a trained barrister who worked as a negotiator for companies such as Sony, Yahoo, Napster, BBC and Apple, has also designed other scenarios as part of the app.
They include negotiating with a partner, asking for a pay rise, and buying or selling a house or car.
