Start Timers on Google Keep Directly in Chrome — TimeCamp Extension
Track time on the quick tasks and checklists you keep in Google Keep, without turning them into a heavier system.
The Chrome extension adds a start button to any note or checklist item, and the note's name comes across as the label on your time. Keep stays the place where you jot down what needs doing; TimeCamp becomes the place that tells you what it costs.
TimeCamp Extension for Chrome is free to use, and so are all its integrations.
