Verdict

The call

The clearest difference is in-app purchases: BLK CARDS at none against Buffer's 12. BLK CARDS also leads on rating (5.0 vs 4.7) and iOS requirement (12.0 vs 18.0). Buffer's advantage is ratings volume (35K vs 1) and chart position (#150 vs unranked). On price, update cadence, ads and device support there is nothing between them.
