Not the best app, it works fine but it can be overwhelming with matches. There is also no way to stay under the radar with friends or coworkers which is a bit odd. I had to delete the app because there were to many notifications. The profile page did ask really good questions though.
Sephora has great products and the return policy is amazing. You should go in during the down time so you can ask questions and receive a tutorial. I tend to do research before I go in which helps. Have an idea and get advice. Also be sure to ask for samples.
Venmo was useful in being able to go out with large groups of friends. After the security issues I deleted the app and notified my bank. I will not be using the product till I am certain they have fixed the issues.
