The differences you'll notice every day

Both turn plain words like $40 in euros into answers line by line, convert currencies and units live, and work with Alfred. The choice comes down to 2 things: whether you need your sheets on an iPhone or iPad, and whether you want to pay $59 or start free.

Our verdicts

Soulver app iconSoulver

Every line in a Soulver sheet can use an earlier answer, so changing your rent figure updates the whole monthly budget beneath it. You write sums in plain words, convert currencies and units as you type, and version 4 adds trip planning and hashtag totals. At $59 for Mac, iPad and iPhone it is a serious purchase, so use the 60-day trial or get it through Setapp; Numi handles lighter math free.

Numi app iconNumi

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.
