Understand the Data analysis tab

The Data analysis tab turns your readings into a few simple summaries: your average, the direction your values are taking, and how often they fall into each category. The main summaries are free. More detailed sections need Premium.

The tab only describes your readings. It does not diagnose anything. As the app says at the bottom of the screen: For informational purposes only. Categories are based on published guidelines and do not constitute a medical diagnosis. Always consult your doctor.

Open the analysis

Tap Data analysis, the fourth icon in the row at the top of the screen. It appears once you have saved three readings.

This page describes the newer version of the screen, with buttons for 7, 28 and 90 days at the top. If you see the older version, scroll to the bottom and tap Switch to new statistics. See The older screen below.

Choose the period

At the top, tap 7, 28 or 90 days. All three are free. The screen opens on 7 days each time.

What the free sections show

• Average blood pressure: the average of your systolic and diastolic values in the period, the number of readings, and the category of the average. With Premium, it also compares the average with the period before.

• Trend: a line of your systolic and diastolic values over the period, with each point in the colour of its category.

• Measurement distribution: how many of your readings fall into each category, as bars, with your highest and lowest values.

• Health Metrics: your average pulse, and your weight and oxygen saturation if you recorded them. It also shows two values the app calculates from your readings: mean arterial pressure (MAP) and pulse pressure (PP). Each value has a label showing which range it is in, such as In range or Above range. Tap the info icon to read what a value means. With Premium, small charts show how each value changed.

The categories follow the guideline chosen in the settings; see Choose the guideline for the colours and categories.

What needs Premium

Below the free sections, Premium adds:

• the time of day: your averages in the morning, afternoon, evening and night;
• a correlation chart of systolic against diastolic values;
• how steady your readings are: the usual change between readings and the biggest jump;
• patterns linked to your tags and to the weather, once you have 12 readings in the period;
• the comparisons with the period before, mentioned above.

Without Premium, these sections are listed under What's included:. Tap Unlock with Premium to see the offer. See Premium.

When a section is empty

Each section needs a few readings. Until then it shows how many more you need, for example "Add 2 more readings". The averages need at least three readings in the period. If you have no readings in the period, the screen says so and offers Add measurement.

The analysis and your filters

The newer analysis always uses all readings of the selected profile. A filter you set in History or on the chart does not change it.

The older screen

Some people still see an older version of the tab, with a list of cards and a filter icon at the top. On that screen, the 7-day summary is free and the 28- and 90-day summaries need Premium, and the filter applies to the cards.

To switch to the newer version, scroll to the bottom of the tab and tap Switch to new statistics. To go back, tap Switch to old statistics at the bottom of the newer screen.

What to check if it does not work

• There is no Data analysis icon, or the tab shows Add more measurements to get free statistics and insights. Save at least three readings.
• The screen shows Too little data.. Add more readings, or choose a longer period.
• The numbers do not match History. The analysis ignores filters, while the list in History follows them. Clear the filter there to compare.
• A section you expected is missing. It needs Premium, or more readings in the period.
