Polar seems like a neat project, but I worry about things like this that are supposed to take on my whole digital life. At one time in my life, I trusted Thunderbird. It got slower and slower, until simple actions (rendering the preview for an email) took thirty seconds or more. At a small scale, this is all well and good, but a lack of foresight around performance means that the biggest power users get punished. How do I know that this won't get dirt slow after the first 1000 (10k? 100k?) documents? Will it lock up my phone trying to crunch through a full text search of a gig of data? It's almost never the case that I see a project like this and have distrust for the mission/philosophy/model/values. But if it can't do what I need it to reasonably, it'd might as well not exist. And I'm not willing to use it for years at a time to find out that it doesn't scale to the point where I need it to. And to be quite honest, I'm more than willing to pay someone to keep a server running to make sure that it does scale and doesn't melt my phone, but that rarely seems to be an option for projects like this.
