How does the connection between YAZIO and Apple Health work?

In the development of YAZIO version 7.2.0 we have also improved our synchronisation between YAZIO and Apple Health. Overall, we would like to point out that the following requirements must be met:

  • iOS 12 or higher
  • YAZIO 7.2.0 or higher 
  • In your iPhone settings > Health > Data access > YAZIO you have to enable all read and write permissions especially for the active energy

What exactly has changed regarding the transfer?

The biggest change is that YAZIO now transfers activity calories to Apple Health! 🚀

Until now, we have transferred the step count from Apple Health and then used this in the YAZIO app to calculate the activity calories. In some cases, this led to steps entered in Apple Health that already had activity calories being counted twice in YAZIO.

Now we transfer our calculated activity energy for steps to Apple Health. There, the data is compared with all stored entries, including data from other third-party providers. YAZIO then uses the activity energy calculated by Apple Health for the day. In this way, we prevent data from being transmitted incorrectly or twice.

A quick example:
Apple Health records activity energy from 1PM to 2PM. YAZIO records activity energy from 1PM to 1:15PM and transfers this value to Apple Health. Apple Health recognises that there are two values for the period 1PM to 1:15PM and subtracts them.

What does the value in the step card and the flame mean?

The value in the orange step card is the value that YAZIO has calculated for your steps. The value in the flame appears when you connect YAZIO to Apple Health or a third-party provider and shows your synchronised activity energy.

If you only enter your steps manually or do not use other apps to record steps, the value under the flame always corresponds to the value in the step card.

However, these values may differ if you have several devices (e.g. your Apple Watch) or other apps connected to Apple Health and transfer these steps. Please see our instructions for Case 2 and Case 3.

Case 1: I only use my iPhone and have exclusively connected YAZIO with Apple Health.

The following information is only applicable if you do not use an Apple Watch or other fitness apps. If you do, please read our instructions for cases 2 and 3.

We first transfer our self-calculated activity energy to Apple Health. There, the data is compared with all stored entries and simultaneously recorded data is deducted. The result is then transferred to YAZIO and displayed as a flame. The activity calories (flame) displayed in YAZIO are identical to the value in Apple Health.

You can edit whether the YAZIO value or the Apple Health value is used for overlapping periods by prioritising data in Apple Health, but this should generally not be necessary:
Browse -> Activity -> Active Energy -> Data Sources & Access -> Edit -> Data Sources -> you can edit the ranking of data sources via the three lines on the right.

Case 2: I only use YAZIO, but I also have my Apple Watch connected to Apple Health.

In this case, it may be that both the Apple Watch and your iPhone record steps. By default, Apple Health prioritises the steps recorded by the Apple Watch.

You can edit the prioritisation as follows:
Apple Health Browse -> Activity -> Active Energy -> Data Sources & Access

Case 3: I use YAZIO, Apple Health and another fitness tracker.

When using other fitness apps or pedometers, it is possible that they record data at the same time.

To avoid mistakes, please check the following:
Please select Browse -> Activity -> Active Energy -> Data Sources & Access in Apple Health. Click on the other fitness tracker below Data Source and select the data for today.

Now there are two cases: 

  1. The additional fitness tracker writes data for the entire day (timestamp 23:59), as one entry. 
  2. The other fitness tracker enters the data with an exact time, e.g. 12:09. 

In the first case, we ask you to activate the transfer of activity energy to Apple Health only for the fitness tracker or YAZIO. You can set this in your phone settings -> Health -> Data Access & Devices -> YAZIO (or the other fitness tracker) -> Allow YAZIO to write Data: Active Energy (disable & enable).

Please ensure that the reading permission is maintained.

In the second case, please adjust the prioritisation of the data sources. YAZIO should be prioritised lower than the other fitness tracker to achieve a more accurate result. 

You can adjust the prioritisation under Browse -> Activity -> Active Energy -> Data Sources & Access -> Edit -> Data Sources -> you can edit the ranking of data sources via the three lines on the right.

We wish you a lot of fun with YAZIO and Apple Health!
