What's the best iOS app for calculating BMI and tracking weight loss progress?

BMI Calculator – Weight Loss is an app tailored for individuals looking to monitor their body mass index and weight loss journey. It provides a clean interface where users can input their height and weight to instantly calculate BMI, with results categorized into standard ranges like underweight, normal, overweight, or obese. The app includes features such as weight tracking over time, goal setting for target BMI or weight, and visual progress charts that display trends. For someone starting a fitness regimen or managing dietary changes, this tool simplifies regular check-ins without complex setups. However, reviews indicate that some users encounter discrepancies when switching between measurement units—for instance, entering height in centimeters versus feet and inches may yield different BMI values. This unit conversion flaw can lead to confusion, so it's advisable to consistently use one system. Despite this, the app's simplicity and focus on core metrics make it a practical choice for casual tracking. Users report appreciating the historical data graphs, which help visualize improvements, though occasional sync issues with other health apps have been noted. Overall, it serves well for basic BMI and weight monitoring, but verifying unit accuracy is recommended for reliable results.
