Hi there! I understand that you’ve had no signal on your Kardia app for two weeks, and after uninstalling and reinstalling the app, it won’t accept your email login. Let’s work through this together.

First, just to clarify:
- Which Kardia device are you using? (e.g., KardiaMobile, KardiaMobile 6L)
- When you say “won’t take my email,” do you mean the app doesn’t recognize your email, or is there an error message when you try to log in?
- Also, have you checked if your email is working fine on other apps or websites?

Meanwhile, here are some steps we can start with:

1. Verify Email and Password: Make sure you’re entering the same email and password you used before. If you’re unsure, try resetting your password through the “Forgot Password” link on the login screen.

2. Update the Kardia App: Sometimes reinstalling might install an outdated version. Ensure you have the latest version of the Kardia app from the App Store.

3. Restart Your iPhone: A simple restart can fix temporary glitches affecting app performance.

4. Check Bluetooth and Permissions: Since Kardia devices rely on Bluetooth, ensure Bluetooth is enabled on your iPhone. Go to Settings > Bluetooth and confirm it’s on. Also, check Settings > Kardia app and make sure all permissions (Bluetooth, Notifications, etc.) are enabled.

5. Check Battery and Device Status: If you have a Kardia device with a replaceable battery, consider replacing it, as a weak battery can cause no signal issues.

If these initial steps don’t resolve the email login issue or signal problem, we can dig deeper into account verification or device-specific troubleshooting.

Could you please provide the extra details I asked for? That will help me tailor the next steps perfectly for your situation.
