Editor's Overview

SrednaBG is a navigation application developed by Stanimir Karoserov, packaged as a single Android APK of version 2.0 weighing in at 92.34 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 92.34 MB, so it installs quickly even on modest connections.
This build is signed by "Stanimir Karoserov" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

SrednaBG shows your real-time running average speed inside Bulgaria's average-speed camera zones — and tells you the maximum speed you can sustain for the rest of the zone without going over the limit.

Free. Open source. Bulgaria only.

WHAT IT DOES

• Running average, live — The moment you enter a zone, your running average becomes the hero number. No lag, no jitter. Updates every second.

• Max now — Shows the top speed you can drive for the rest of the zone without breaking the limit. Waze tells you the zone exists; SrednaBG tells you what to do about it.

• Green / amber / red at a glance — The screen color tracks your state. Green: within limit. Amber: careful, slow down. Red: already over.

• Voice alerts in Bulgarian and English — Keep your eyes on the road. SrednaBG speaks zone entries, exits, and slowdown warnings in the language you choose.

• Works fully offline — The Bulgaria map and zone list are bundled inside the app. No internet needed in the car. Updates arrive quietly when you're on Wi-Fi.

• Alongside Waze, or instead of it — Run SrednaBG as a full navigator, or let it sit quietly behind Waze / Google Maps — you'll hear its voice when it matters.

PERMISSIONS, EXPLAINED

• Background location — Average-speed zones can be many kilometres long, and a drive often outlasts the screen timeout or runs behind another navigation app. SrednaBG needs location while in the background so your average keeps updating with the screen off or another app in front. It is used only to compute your speed inside zones — never shared, and it never leaves your phone.

• Ignore battery optimizations (optional) — You can grant an exemption so the system doesn't suspend tracking mid-drive. It is optional and requested only from a card you tap; tracking still starts without it, just less reliably on devices with aggressive power management.

PRIVACY

• No cookies, no trackers anywhere.
• No account, no email, no signup. Install and drive.
• No ads. No in-app purchases. Free forever.
• No third-party SDKs. No Google Analytics. No Firebase.
• Your location never leaves your phone.

Frequently Asked Questions

Is SrednaBG free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does SrednaBG require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is SrednaBG safe to install?
We link to the exact APK published by Stanimir Karoserov. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update SrednaBG?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
