I get no results for Apple Watch measurements

  • Most probably, Welltory doesn’t have enough permissions to receive the data.

Go to Apple Health, open the Sources tab, find Welltory in the list of connected apps, and make sure it has access to all data categories (both to write and to read data). If you don’t see Welltory in the list of connected apps in Apple Health:

  1. Go to the Welltory app.

  2. Open the Menu.

  3. In Sources, choose Apple Health.

  4. Tap Connect.

  5. Turn all categories on and tap Allow.

  • If the measurement is too short (less than 50 heartbeats) — you won’t get chart or liquid messages, nor will the measurement appear in the Measurement History.

You’ll see such short measurement in the feed as a simple message with SDNN.

Your watch takes background measurements only when you’re relaxed. That’s why it often records less than 50 heartbeats, and we don’t get enough data to analyze. Although you can’t control background measurements, you can “force” your watch to take a measurement if you want. Open the Breathe app, set the session length to at least 3 minutes, and breathe naturally, ignoring the watch’s guidance. Such measurement’s length will usually exceed 50 heartbeats. Find more on measuring heart rate variability with Apple Watch here.

  • Another reason — the results seem physically impossible (outside the physiological norm).

It happens when the signal is unclear, e.g. contains noises or arrhythmias which our algorithm can’t filter out. It’s often the case when you move or talk during a measurement. Find more on what affects measurement quality and how to improve it here.

If it’s an Apple Watch measurement taken in the background, we’ll just ignore it.

If it’s an Apple Watch measurement taken with the Breathe app, we’ll send you a message about its low quality.

  • Sometimes, data synchronization may take a little too long, or the results may be running a little late.

Data from Apple Health may have not yet reached Welltory. Or data transfer from Apple Watch to Apple Health may have taken longer than usual. If you see your measurement in Apple Health, but not in Welltory, give it 10–15 minutes to sync — this time is usually enough.

When we analyze your measurements, we take into account your previous results and a lot of other data. It takes time. Usually, measurements are analyzed within 5–10 seconds, but sometimes it may take longer. If you’ve excluded the reasons above but still see absolutely nothing in your feed after a measurement — just wait a bit, the results will be there soon. If you close the app while waiting, you’ll get a push notification when they come.

FAQ

Why do I see no measurement results in my feed, while they are in the Measurement History?

It can happen with Apple Watch measurements taken in the background:

  • If you already have a high-accuracy measurement this time of day. We don’t want to clutter your feed with unnecessary information. Remember that measurements taken during the day mostly reflect your body’s responses to what’s happening. Your body’s general state is better captured by morning measurements.

  • If it’s a measurement taken during the night while you’re asleep. Exceptions may happen in the following situation: you wake up during the night — you Apple Watch notes it and takes a measurement — we send the results to your feed not knowing you’ve fallen asleep again.

Why do I get no message with the Productivity, Energy, and Stress scores after getting a message with a chart?

There may be two reasons for that:

  • The measurement’s accuracy isn’t high enough for our algorithm to calculate your Productivity, Energy, and Stress scores. Find out what affects measurement quality and how to improve it here.

  • You took two high-accuracy measurements, one after another, but the latter’s accuracy is lower than the former’s. In this situation, you’ll get both chart and liquid messages for the first measurement and only a chart message for the second one — because your Productivity, Energy, and Stress scores were more accurate in the first case.
