Verdict

The call

The clearest difference is rating: Buffer at 4.7 against ZOLEO's 3.7. Buffer also leads on update cadence (every 5 days vs every 2 months) and ratings volume (35K vs 104). ZOLEO's advantage is in-app purchases (none vs 12) and iOS requirement (13 vs 18.0). On price, review sentiment, ads and monetization model there is nothing between them.
