So many small things, combine to make my and my family’ daily life easier. As for lesser known, I’d say Tandoor. A web based UI for your recipes. I cook the most for our family, but old school like; add this and this, and enough of this until it tastes good. My wife needs more instruction. So with this, if I cook something she wants to eat again; she tells me. I then write down that recipe on Tandoor so it can be reproduced. I also got started with this software back when it was called just ‘recipes’.

Quality software, great usage. Lesser known.
