How does Numi compare to Soulver 3[0]?

I have your exact question in mind. If the OP hasn't tried Soulver, they must! It's a gem of computing for me and I lean on it regularly.

I have a single, but major, complaint with Soulver: version 3 for iOS/iPadOS doesn’t exist yet. There are a lot of calculations I’d want to do both at my desk and out on the road, and I’d like them synced. Calca handles that pretty well and I’ve been using it over Soulver lately for that one specific reason. I like Soulver more than Calca, though, and the second Soulver 3 for iOS comes along I’ll switch back.

Bummer, no RPN for Soulver, Numi, or SpeedCrunch.
