Have you connected a calorie-burning habit (like your Apple Watch's "Move Goal") to Apple Health, only to see a massive, unexpected number appear in Habitify? For example, your goal of 500 Calories suddenly shows up as 500,000.
Don't worry—this is not a bug! This happens because of a simple but important difference in the units of measurement used by Apple Health and Habitify.
The Key Difference: Kilocalories (kcal) vs. Calories (cal)
The source of the confusion is the difference between a "Calorie" and a "calorie."
Apple Health uses kcal: The Apple Health app, like most fitness trackers and nutritional labels, measures energy in kilocalories (kcal). This is often written as "Calories" (with a capital C) as a shorthand.
Habitify uses cal and kcal: Our app offers both units. The smaller unit is the "calorie" (cal), and the larger unit is the "kilocalorie" (kcal).
The conversion rate between them is: 1 kcal (in Apple Health) = 1,000 cal (in Habitify)
A Practical Example
Let's say your "Move Goal" in the Apple Fitness app is to burn 3,000 Calories. This actually means you are burning 3,000 kilocalories (kcal).
If you create a habit in Habitify and set the goal unit to the smaller "calories" (cal), the app will convert the units when syncing:
Calculation:
3,000 kcal(from Apple Health)x 1,000 = 3,000,000 calResult: This is why you see the number 3,000,000 in your Habitify progress for that day.
The Solution: How to Set Up Your Habit Correctly
To ensure the numbers from Apple Health match what you see in Habitify, you simply need to select the correct unit when creating your habit.
When you create your calorie-tracking habit in Habitify (e.g., "Burn Calories"), tap on the Goal section.
Enter your target number (e.g., 500).
In the unit selection, make sure to choose kcal, not "cal".
Link the habit to Apple Health by selecting "Active Energy".
Now, when Apple Health syncs 500 kcal, Habitify will read it as 500 kcal, and your progress will be displayed correctly.
What if I already created my habit with the wrong unit?
It's an easy fix! Simply edit your existing habit. Go into the habit's settings, tap on the goal, and change the unit from "cal" to "kcal". Your progress will then sync and display correctly.
