Bit of feedback on uruky - biggest gap I experienced was lack of calculator and currency converter rather than the quality of results. Stuff like "50 GBP in USD".
It's something we've felt has been best served by the OS at this point (macOS and Linux, at least), and adds significant complexity (we need to start tracking multiple currencies, their current exchange rates, parse different regex/ways of people doing that), so we've been reluctant to add it so far.
I'd be curious to understand if you bypass those OS entry points (and why) and use search for those things.
