OnePageCRM's answer
OnePageCRM is the first action-focused CRM in the world. This simple CRM is built for small businesses and has a powerful task management functionality. OnePageCRM doesn't only sort contacts from A to Z but also has a unique Action Stream feature. In the Action Stream, all contacts are sorted by the urgency of their assigned task or follow-up reminder. This way, you have both a central contact management system and a dynamic to-do list in one app.
