I use: tomato-timer.com, and I use the basic 25/5 or 25/10 for a longer rest. I set the bell tone I want and tell it to go continuously (that's "auto start" under settings). I get myself ready, close out wasting time tabs, open my document, make sure I have my water by my side, and press "start." Then I do my 5 or 6 sprints and usually am done for the day.

I’d recommend using an app called StretchMinder which reminds you to take breaks and guides you through movement routines so you don’t need to think about what to do. It’s an easy way to get started with this habit. Source: over 3 years ago
