Simple by design
Just the numbers that matter: calories in, calories out and net. Carefully curated, glanceable information when you need it.
Flexible by nature
Eat in a way that suits you and move how you want. Flex calories in and out from day to day. It's the weekly trend that counts.
Net is the key
Calories in minus calories out is what drives your weight. See it by day, week, month or year, and know if you are ahead or behind.
Works wherever you are
On your phone, your tablet or your watch, so the numbers are always close at hand.
Everything you need, nothing you don't
A calm, quick-to-read dashboard for people who already track their food and activity somewhere else.
Three rings, one glance
Calories in, out and net for the day, each against your own target.
This week: ahead or behind
Adds up how far each day since Monday is from your daily target, so one bad day doesn't hide the bigger picture.
Any period you like
Switch between day, week, month, 3 months, 6 months and a year, with averages that make trends easy to see.
Today's projection
An optional estimate of how today will finish, based on your average resting calories from recent days.
Workouts
See how your sessions contribute to what you burn.
Progress
Weight and body fat over time, how much you have lost in the period, and how far you have to go to your goal.

How it works
CaloriesIO doesn't ask you to log meals again. It reads what your existing apps and devices have already recorded.
Connect your health data
Allow access to Apple Health on iPhone or Health Connect on Android. You choose what to share.
Set your targets
Enter your daily calorie targets and, if you like, a goal weight and date.
See where you stand
Open the app, glance at your watch or add a widget to your home screen.
On your wrist and home screen
An Apple Watch app and a Wear OS app show your rings and whether you are ahead or behind, and widgets put the numbers on your home screen. Your phone and watch share data directly with each other, on your own devices.
