Verdict
The clearest difference is in-app purchases: Kilo at none against Weight Tracker's 1. Kilo also leads on ads (none vs shown). Weight Tracker's advantage is update cadence (every 5 days vs fortnightly) and iOS requirement (16.4 vs 26.1). On price and device support there is nothing between them.
