Sarahah – The “Honesty App” that has everyone talking – or at least 300 million users! Originally devised to allow employees to submit truly anonymous feedback to their companies, the service has expanded to an app that allows users to register and publicly (or to a select few) invite anonymised messages of feedback. Controversially making headlines due to the obvious risks of cyberbullying, Sarahah has been integrated into Snapchat, resulting in a large proportion of teen user registrations, culminating in growing concerns from parents around the world. Know someone who could use a little feedback? There’s an app for that!
