Verdict
The clearest difference is in-app purchases: polestarM at none against eClock!'s 1. polestarM also leads on ads (none vs shown) and update cadence (fortnightly vs every 2 months). eClock!'s advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price there is nothing between them.
