SrednaBG
APK
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. Open source — MIT License. Source code: https://github.com/demosten-com/SrednaBG

APK
There are slides and you click to stack the slides and try to stack them perfectly. Bright colors. Gameplay: * A block slides back and forth above the tower — tap to drop it. * Whatever hangs over the edge is sliced off and tumbles away. Whatever remains is all the next block has to land on. * Miss the tower entirely and the run is over. * Frame perfect: land within one frame of travel of dead centre and the block keeps its full size, and the placement scores double. * The slide speed ramps up as the tower grows, and consecutive frame perfects raise the chime pitch. Stack Tower 3D is free and open-source software, licensed under the GNU General Public License v3.0. Built with libGDX.
