Weight Chart helps to monitor your weight and waist circumference over time. Newer studies show that a waist to height ratio of over 0.5 increases the risk of cardiovascular diseases, a ratio over 0.6 significantly. It's a better measure than the well known body mass index (BMI) because it takes the distribution of fat into account more accurately.

Verdict
The clearest difference is review sentiment: Goal BMI at 100% against Weight Chart's 29%. Goal BMI also leads on price (Free vs $0.99) and rating (4.9 vs 1.0). Weight Chart's advantage is update cadence (every 6 months vs every 19 months) and iOS requirement (12.0 vs 15.0). On ads, in-app purchases and device support there is nothing between them.
