It sounds easy enough: Ask a thought-provoking question and you'll set the right atmosphere for a psychologically safe group meeting that's conducive to collaboration and learning. Yet, as effortless as that can sound, many of us can attest to racking our brains or performing endless online searches to find inspiration for the right question to break the ice in our training sessions.

Next time you are feeling stuck, try the Let's Talk app. Use the tool to launch strangers into ice-breaking, tension-releasing, comfort-building banter. Available to Apple users, the $1 app provides more than 1,200 questions grouped into nine different categories, including small groups, business groups, and even dinner with friends. After selecting a category, you may also select the question's level of difficulty.

Whether for a weekly team meeting or a large-scale training event, icebreakers can have a great effect on participants' engagement level. And the questions available on Let's Talk can help you get the conversations started.
