Why is my timeline showing the wrong time or timezone?

Cardiogram uses your phone’s system timezone to display timestamps in the Timeline. In most cases, it should update automatically — but if you’re seeing incorrect times, here’s how to fix it.

🕒 Manually update your timezone in Cardiogram (iOS only)

Open the Cardiogram app
From the Timeline screen, tap the three horizontal lines (☰) in the top left corner
Tap Settings > General
Scroll to the bottom
Use the Timezone dropdown to manually select your correct timezone

✅ This option is currently available for iPhone users only

🔁 Resetting your timezone manually (iOS workaround)

If the timeline still appears off, try this reset method:

Open your iPhone’s Settings app
Tap General > Date & Time
Temporarily change to a different timezone
Open the Cardiogram app
Go back to Date & Time and switch back to your correct timezone
Reopen Cardiogram again

This often forces a refresh of the timezone setting in your Timeline chart.

💡 Android users

Cardiogram should always follow your system timezone on Android. If times look off, try:

Restarting your phone
Opening Cardiogram again after confirming your phone’s timezone is correct
