Numi

Calculator that blends plain text and math

MacFree to start

The verdict

Spotlight converts one thing at a time and forgets it the moment you close it. Numi keeps a running page of math written as plain text, like $40 in euros or today plus 3 weeks, with an answer on every line, plus time zones, crypto and named variables. The download is free, but unlimited notes and iCloud sync need the $29.99 license; Soulver costs $59 and adds iPhone and iPad versions.
