You can use up to 10 band pass filters, represented by bubbles in the UI, with controllable resonance. Each band can have a dedicated delay with feedback.

Verdict

Arpeggist's advantage is update cadence (every 5 weeks vs every 32 months) and price ($2.99 vs $6.99). On ads, in-app purchases and monetization model there is nothing between them.
