Hi there! I understand you're having trouble updating the Livongo app on your iPhone. Let’s figure this out together. Could you please share if you're seeing any error messages when trying to update, or is it that the update simply isn't starting? Also, can you confirm if your device is connected to the internet?

With a bit more information, I can guide you through some steps to resolve this.

It said update app I tap update it just keeps going back to update.

Thank you for the additional details! It sounds like you're experiencing an update loop with the app. Let’s try to resolve this with a few steps.

1. Close and Reopen the App:
- Swipe up from the bottom of the screen (or double-click the Home button on older iPhones) to see the app switcher.
- Find the Livongo app and swipe it off the screen to close it completely.

2. Restart Your iPhone:
- Hold the power button and either volume button until the "slide to power off" slider appears.
- Slide to turn off your iPhone, then press and hold the power button again until you see the Apple logo.

3. Check for Available Updates:
- Open the App Store and go to the "Updates" section by tapping on your profile icon in the top right corner.
- Pull the screen down to refresh it, then try tapping "Update" again for the Livongo app.

4. Free Up Storage Space:
- Go to Settings > General > iPhone Storage to see if you have enough space available. If you’re low on storage, try deleting some unnecessary apps or files.

5. Log Out and Log Back In:
- If the issue persists, try logging out of your Livongo account in the app settings and then logging back in again.

If you've tried all of these steps and the issue continues, you might want to consider deleting the app and reinstalling it. You can do this by pressing and holding the Livongo app icon until it wiggles, then tapping the "x" to delete it. After that, you can reinstall it from the App Store.

Let me know if any of these steps help or if we need to explore other options!
