Checklick lets you record things you do in a logbook. For example, you might want to record that you ran 10km today, or that you ate a breakfast that was 1000 calories.
Your logbook entries can be seen by you and any organization that you are affiliated with.
Some checklists even have special requirements for the log entries that you make. Depending on the organizations you are affiliated with, you may see a few logbook templates that will help you enter the right information for a particular checklist.
