Verdict

The call

The clearest difference is ads: Lockera at none against FirstSeed Calendar's shown. Lockera also leads on iOS requirement (16.0 vs 26.0). FirstSeed Calendar's advantage is update cadence (every 8 days vs every 2 months) and ratings volume (336 vs 17). On price, rating, review sentiment and in-app purchases there is nothing between them.
