Verdict

The call

The clearest difference is monetization model: Calendar at free with in-app purchases against Plannu's subscription. Plannu's advantage is review sentiment (100% vs 70%) and update cadence (every 5 days vs monthly). On price, ads, in-app purchases and device support there is nothing between them.
