Verdict
The clearest difference is ads: Kadam at none against Stardust Period Tracker's shown. Kadam also leads on update cadence (every 5 days vs fortnightly). Stardust Period Tracker's advantage is chart position (#47 vs unranked) and iOS requirement (15.2 vs 17.0). On price, in-app purchases and device support there is nothing between them.
