FAQ
Q: How does the Optimal Pace Guidance feature work?
A: The Optimal Pace Guidance feature acts like a friendly co-pilot by calculating the highest safe speed you can maintain for the remainder of an active zone. If you entered a zone going a bit too fast, the app dynamically calculates how to adjust your pace so you remain fine-free without having to drop down to a painfully slow crawl.
Q: Do I need an active internet connection to use SrednaBG while driving?
A: Not at all. SrednaBG comes with an embedded map of Bulgaria, which means it functions completely offline. You won't need to use any mobile data while driving, making it reliable even in areas with poor cellular reception or for drivers who prefer to keep their mobile data turned off.
Q: Where does SrednaBG get its average-speed camera zone data?
A: The app is built exclusively for Bulgarian roads and utilizes official, verified zone data. This information is meticulously cross-referenced with BG TOLL listings and OpenStreetMap data to ensure high precision and accuracy whenever you are on the highway.
