Frequently Asked Questions

How does Stoplight Pro work?

Stoplight Pro uses advanced AI to detect traffic lights and predict when they'll turn green. The system learns from anonymous driving patterns across our user network, becoming more accurate over time. Your device displays real-time countdown alerts showing seconds until the light changes.

Do I need an active subscription?

Yes, Stoplight Pro requires an active subscription to use the prediction service. We offer two tiers: Standard ($5/month) and Insider ($7/month). You can manage your subscription from your account page.

Does the app need to run in the foreground?

No! The Stoplight Pro app is designed to run in the background. Simply open the app once, and it will automatically connect and work while you drive. You don't need to keep the app open on your screen.

Will Stoplight Pro work everywhere?

Stoplight Pro works best in areas with active users contributing to the network. The more drivers using Stoplight Pro in your area, the better the predictions become. The system continuously learns and improves as the network grows.

Is my location data private?

Absolutely. Your driving data stays private. Only anonymous timing patterns are shared to improve the system for everyone. We never sell or share your personal location data with third parties.

How accurate are the predictions?

Stoplight Pro's AI provides high accuracy predictions that improve over time. Accuracy varies by location based on network density and traffic signal patterns. Areas with more active users typically see the most accurate predictions.

Does the device need to be charged?

No! The device has a large built-in battery that stays topped off through solar charging when mounted on your windshield. Under normal use, the battery maintains charge indefinitely without any cables or external charging. The solar panel continuously recharges the battery while your car is parked in daylight. For backup charging in extended low-light conditions (such as winter months or covered parking), the device includes a USB-C charging port that works with any standard USB-C cable.

Troubleshooting

• Ensure Bluetooth is enabled on your phone
• Make sure the device is properly mounted
• Try force-closing and reopening the app
• Restart your phone and try again
• Ensure you're within Bluetooth range (typically 30 feet)

No predictions showing

• Verify you have an active subscription in your account
• Ensure the app is running (check background apps)
• Check that location services are enabled for the app
• Drive to an area with traffic lights to allow the system to detect signals
• Network learning may take a few trips in new areas

Predictions not accurate

• The system learns over time - accuracy improves with more usage
• Ensure the device display is clean and clearly visible
• Verify the device has a clear view of traffic lights ahead
• More drivers in your area improve prediction accuracy

App battery drain concerns

• Background operation is optimized for minimal battery use
• Ensure you're using the latest app version
• Check that power saving mode isn't restricting background activity
• Consider using a car charger for long trips
