What tool do you use for maintenance of work-life balance?

I use living things: my family talks to me, my dogs remind me when it is time to pet them, selected humans (a.k.a. friends) say hello in person or by phone quite often too.

Our own - tira.so We designed a productivity workspace - tira.so - where startups can communicate with the team, manage all the projects and tasks, and keep track of the schedule. All from one place. There’s no need to switch between apps. We've also got a pretty cool drag & drop feature where you can drag a task to a chat and edit it directly in the chat. We are working on launching Tira on Sep 15th.

At the moment I just use the basic timer with a prominent alarm tone. I try not to stretch it for too long, max 10 mins snooze and then I just get away from technology. Go around the house chatting with family members or just sit by myself reading book, etc I think it's really about disciplining ourselves. Just like we try to get things done on time, we also need to unwind on time. Being aware of your time and state of mind really helps.
