Jinear▲192
Hi HN, Two years ago, I started building Jinear as a side project for fun. Then my wife started using it to plan her PhD thesis. I added features as we needed them. After a while, my best friend started using it in his small company, so I thought maybe I could productize it. You can create tasks, set reminders, attach files, link your Google Calendar, etc. It can be used as a PWA. We've been using it daily. I would be happy to receive your feedback. Thanks.
