Calorie app that works with Apple Health and Health Connect: what it reads, and nothing more
In short
Radish, a free calorie counter for Android and iPhone, connects for free to Apple Health (iPhone) and Health Connect (Android), and reads only one thing there: your daily step count. It writes nothing to Apple Health, and your steps show in your diary without changing your calorie goal (checked in the app’s code on 5 November 2026). Google Play: fr.nutritrack.app · App Store: id6791090193.
Plugging a calorie app into your phone’s Health app often opens access to far more than you think: weight, sleep, heart rate. Before you accept, the right question is simple: what exactly does the app read, and what does it write? Here is the answer for Radish, checked in the code.
On a computer? Scan this code with your phone to install Radish.
What Radish reads
Your step count for the day, and nothing else. The only permission requested is reading steps (the READ_STEPS permission on Android). The connection screen says it plainly: “Reads only your daily step count.” Your weight, sleep, heart rate and workouts are not read.
What Radish does not write
Radish writes nothing to Apple Health: no meals, no calories, no weight. iOS still shows a write-permission request, because the technical library the app uses declares it; the app does not use it, and the text iOS displays says so.
What the steps are for
They show in your diary, with an estimate of the calories burned walking when your weight is filled in. Since 2 September 2026, they no longer change your calorie goal: only activities you enter yourself do. A day with truly zero steps shows zero, and a step count you entered by hand is not overwritten by an empty sync.

- Free: health sync has been free since 27 July 2026, with no subscription or purchase.
- On the phone: the step count is read on the device and saved with your diary. Your journal stays on your phone — never sent to our servers (except for AI and barcode scanning, if you use them).
- Revocable: you can withdraw access at any time in the phone’s Health settings; Radish detects it and shows “Access to your steps was revoked”.
- In the app only: the connection exists only in the Android and iPhone app, not on the website.
For everything that does or does not leave the phone, see what stays on your phone.

Which calorie app syncs with Apple Health for free?
Radish connects for free to Apple Health on iPhone and Health Connect on Android. It reads only your daily step count and writes nothing to Apple Health (checked in the app’s code on 5 November 2026).
Does Radish send my meals to Apple Health?
No. Radish writes no data to Apple Health: no meals, no calories, no weight. iOS shows a write request because the library used declares it, but the app does not use it.
Do my steps change my calorie goal in Radish?
No, not since 2 September 2026. Steps show in the diary, with an estimate of energy burned when your weight is filled in, but only activities you enter change the goal.
Is the Apple Health or Health Connect sync paid?
No. It has been part of Radish’s free version since 27 July 2026, with no account.
On the food side, the food pages on this site give values per 100 g and their source: banana, cooked pasta, salmon and green beans.
