The clearest difference is update cadence: BairnApp at every 3 days against Weight Diary Lite's every 5 months. BairnApp also leads on iOS requirement (16.0 vs 26.0). Weight Diary Lite's advantage is ratings volume (7.3K vs 1). On price, rating, ads and in-app purchases there is nothing between them.
