Verdict
The clearest difference is rating: Spell at 4.0 against Numbers's 1.0. Spell also leads on ratings volume (5 vs 1) and price ($1.99 vs $2.99). Numbers's advantage is update cadence (every 5 weeks vs every 4 months) and device support (3 vs 1). On ads, in-app purchases and monetization model there is nothing between them.
