Verdict

The call

The clearest difference is ads: Zal at none against Off's shown. Zal also leads on rating (5.0 vs 4.6) and review sentiment (67% vs 52%). Off's advantage is ratings volume (498 vs 2). On price, update cadence, in-app purchases and monetization model there is nothing between them.
