Estinate is a hobby project that I've been working on for some time. As a developer, I'm often asked for time estimates, but I've been struggling to find a tool I like for the job.
I really just wanted some simple way to make nested lists and estimate each individual item and share it with project managers and clients.
So I set out to create the tool I wanted myself. At the same time I learned some Rails and Angular!
Feel free to try it out and give some initial feedback! There are still a lot of things to wish for.
