BMI Calculator: Weight Plan

BMI Calculator: Weight Plan is an iPhone app for working out your BMI and keeping track of where your weight is going over time. Alongside the calculator it holds your measurements, short lessons, check-ins, habit tracking and a food and drink log, so the numbers sit next to the context around them.

Everything you enter stays in the app’s own storage on your iPhone. There is no account to create and no server of ours holding your measurements. Apple Health is optional — the app can read your weight and write your weigh-ins back, and it works fully without it.

The app does not diagnose anything and is not a substitute for advice from a professional who knows your situation.
