Alex Lindsay's pick of the week on MacBreak Weekly episode 390 is an app called Secret - Speak Freely. This is an app for sharing secrets anonymously with friends who are in your contact list.
When you create a new post, you can choose either a photo or a solid color as the backdrop. Then people can anonymously comment or "love" your posts. The more people love your posts, the further they will spread out beyond just your circle.
Secret's developers claim that user data is secure. They use Google's servers for storing data, and all data is encrypted. Find out more about Secret's security measures here.
For Alex Lindsay's explanation and recommendation of Secret - Speak Freely, check out MacBreak Weekly episode 390.
