Verdict

The call

The clearest difference is ads: PileStack at none against ABC Contacts's shown. PileStack also leads on update cadence (every 4 days vs every 2 months) and rating (5.0 vs 4.6). ABC Contacts's advantage is ratings volume (1.2K vs 2) and iOS requirement (15.0 vs 17.6). On price, in-app purchases, monetization model and device support there is nothing between them.
