1) The above the fold stuff sort of showed me what it describes itself as, but not what it really is. A looping animation or video would have been really helpful.
2) The below the fold stuff originally came across as separate products. Like I thought it was your catch-all page for a few other products you've made. So maybe you could make it clearer that they are all components of Bee.
3) Just my own reaction that I noticed - when you demonstrate compatibility with several outside services, there might be a weird disincentive to try it out if the potential customer doesn't use all of those services. Like I immediately had a suspicion that since I use Jira but not Github or Fogbugz, that the other focuses of the tool would get in the way or make it feel unwieldy. (I didn't download it to disprove that feeling.)
4) Time/task tracking is a REALLY crowded space, and I imagine it is really difficult to convince someone to try out a new tool, partly because of switching costs. For instance, for me, I use Quickbooks on the Mac, and I'm pretty married to Intuit's "My Time" since it's the only tool I know of on the Mac that will automatically transfer time records to Quickbooks, which I then use to make invoices. And then if someone asks me why I create my invoices from time records in Quickbooks, then... heck, I dunno, I made the decision at one point and it works for me. I could do a whole first-principles analysis I guess that might lead me to a completely different way of working that might lead me to being able to using a different time-tracking app like Bee, but... I don't like going that low on my e-Maslow's hierarchy very often.
5) No obvious mention of price on the front page... no obvious indicator of what clicking the "Buy" button will do or where it will take me. I moused over it, looked for an info tip, and didn't click. (I'm one to just buy rather than deal with download/try/maybe-buy.)
