I got a new iPhone & now Gyroscope doesn’t open

If you are switching phones, we suggest logging out of Gyroscope and deleting the app prior to migrating from one phone to the other.

It is counterintutive, but the simplest and cleanest way to make sure you can set it up again one you get your new phone set up.

The automatic backup process doesn’t handle Gyroscope’s realtime syncing and complexity well, so you’re better off just installing it again rather than trying to transfer it.

If you restored your phone from a backup onto a new phone and it automatically copies over Gyroscope, this can create issues and will likely cause the app to crash.

The backup process doesn’t fully duplicate your previous phone, and so introduces many possible complications that could cause Gyroscope to crash — including only partially copying over the app setup, not transferring certain required permissions, copying bad data into Apple Health, or resyncing old data from Apple Health while it redownloads. Even if it doesn’t crash, you may be missing some permissions or data access, so it is best to set it up correctly on a new phone. This should only take 2-3 minutes every year or however often you get a new phone.

The first thing to try is to delete the app, restart your phone, and then reinstall the latest version from the App Store. This should let you log back in and start setting it up.

Then log back in, re-enable Apple Health & Places permissions, and continue where you left off!


When you try to delete the app, you will see this scary warning. Ignore it!

It is not true, your data will not be lost.

“What about my data!?” you ask? Fortunately, that is not stored in the phone, and should not be affected.

Your actual data is stored in your Gyroscope account and just synced and displayed on the phone, just like it is on the website. You can log in to your account on the website to review what all is there.

However, it is critical you log back into the same account. Most people should only have one Gyroscope account, so it is just a matter of remembering your email or username and password and should be easy. Where this process can go wrong is if you log back into another account, or create a new account when you come back.

If that doesn’t work…

1 Wait a while until your backup is fully completed restoring

Sometimes people will install the app right when their new phone is opened. If your Apple Health data is still being restored and copied from an iCloud backup, that could cause issues as Gyroscope has to try and sync millions of data points as they get added back in.

You may want to wait a few hours to until your phone is in a stable configuration and make sure the backup has completed before attempting to set up Gyroscope syncing. Trying to keep up with this firehose of data can also cause the app to crash while it is running.

2 Try running the app in a simpler mode

When you first set up the app, you should see a prompt to set up Apple Health, places, etc. Instead of turning everything back on, you can leave all of these off — and not grant any requested permissions in Apple Health — to skip the syncing and see if that fixes the issue.

If that is the case, something about those data points is causing the crash. Since millions of apps can write to there, it is possible one of them has put bad data that can’t be synced or causes a crash. Then you can selectively start turning them on to narrow it down.

This is quite rare, but is known to happen as there are many apps out there. For example, at least one person has a weight measurement that is larger than the mass of the earth and too big to store or upload successfully, and trying to do so could cause a crash. The more apps you give access to write to Apple Health, the more possibility there is of this happening.

3 Try deleting and reinstalling

Generally, deleting the app or logging out should also reset the app.

4 The most extreme option would be to fully reset your phone

Sometimes there is something wrong with your phone or your OS setup, especially if restored from a previous backup and not from scratch and corrupted in some way. This is rare but can happen.

This will let you set up the app cleanly without bad data or a strange configuration caused by the backup. This is typically not necessary, but should resolve the issue.
