CrowdCall is a specialized conference-calling app for iOS and Androids created by the founders of SocialDial. SocialDial allowed LinkedIn users to call contacts through their user profiles without users having to know the phone number. The founders of this app realized that users were taking advantage of the group-calling option. This inspired the creation of CrowdCall. The app allows users to choose up to 20 participants from their contact lists and LinkedIn connections (if the user has a number associated with the profile) and dial immediately. The free version allows up to 500 minutes per month. The premium packages are $9.99 for 1,000 minutes, $49.99 for 10,000 minutes and $99.99 for unlimited monthly minutes.
