FeedbackHero is an iPad mounted on the exit, where customers can give their quick feedback in 2 clicks that take less than 20 seconds. Our experience in a few hotels in San Francisco shows up to 35% of the guests giving feedback due to its shine, simplicity, and speed.

We provide real time SMS/Email updates to the managers when a customer is unhappy about something, so that they can fix the issue before the customer walks out. We also provide an online interface to quickly change the survey questions, and to generate detailed reports about customer satisfaction over hours/days/weeks, across different branches.
