Sure, for that use case you really can’t do better than one of the existing small field or voice recorders on the market, or your phone potentially.
I was thinking about getting another super pocketable recorder for this kind of thing and was considering the Sony A10 which would be near the top of the list I guess. There’s a few other similar options out there from OM System or Tascam, but I don’t know if they would be any better.
