I struggle to focus working from home so I built a solution▲31
Hey HN friends, I keep getting distracted working from home and always end up watching youtube, browsing blogs like HN or just mindlessly scrolling then I feel like crap because I didn’t do enough. I went through dozens of productivity tools but they’re quite overwhelming to use and none of them actually helped me focus. So I built http://complish.ai, a web-based sidebar that helps me focus on one task at a time. I launched it last month and have over 3,000 users now and I’ll be keeping it free. Would love for you all to try and give some feedback!
