WeProfile

WeProfile is an app that lets you enter a phone number and check out a person's WhatsApp profile. The problem? Not only does it not always work but it also requires you to pay for a subscription. When it does work the app is at least quite easy to use: just enter the phone number and the country code, and within seconds you'll have all the corresponding info. The paid version of WeProfile lets you do this whenever you want, while the free version just lets you do it twice a day.
