4. TimeToMeet
   
   TimeToMeet is a web-based tool that helps people finding a common meeting time. When you create a meeting with TimeToMeet, every participant receives a personal link that they use to access TimeToMeet and respond to your request. TimeToMeet will ask everyone for times when they are available, meaning: when it's most convenient for them to meet. As everyone replies, TimeToMeet calculates the overlap and notifies you so that you can confirm a final time. TimeToMeet is free but a Pro version is available at $3 for 3 months or $5 for 6 months. All Pro features are available for the free plan subscribers during the first month
