Every year, thousands of drivers get fined by a camera they never saw. A hidden mobile radar. A section camera your sat-nav didn't know about. A speed limit sign you missed. Suddenly it's a €200 fine and points on your licence. Most speed camera apps are slow and bloated. RadarIO is 9.6 MB and opens instantly. EVERY CAMERA ON YOUR ROUTE Fixed cameras, mobile radars, section controls and red light cameras. 79,000+ of them worldwide, refreshed every week. Other drivers report mobile radars, and you are warned about them like any other camera. Where they are set up again and again, the app remembers the spot. And every ten of your reports that other drivers confirm earn you a free month of Pro. In Spain, also the zones where the DGT deploys mobile radars, on the map and announced as you enter and leave, and its seatbelt and phone cameras. And your own radars: press and hold the map on that spot where there is always one, and you will be warned every time you pass. You get voice, sound and vibration warnings, at the distance you choose for each speed limit. You also get the limit itself, so you know what you are being measured against. Licence plate readers too, if you want them. They are off until you turn them on. They cannot fine you for speeding, so they get their own warning and never appear in your radar history. SEE HOW YOU ACTUALLY DRIVE Every drive is recorded on its own, and you can name it and file it in folders. Distance, time, your fastest routes, and the speed you passed each camera at. The road gets painted by how you drove it, compared to your own history. A live delta you can switch between your average, your best, and the limit. Replay a drive on the map with its speed graph. Follow it again turn by turn, along the same roads. Or put two drives on the same road side by side, plotted against distance instead of the clock, with both cars running at once. WHEN THE SIGNAL DROPS In a tunnel, the car keeps moving along the road instead of freezing, so exits and cameras are still announced. The app learns where your own signal dies and downloads the road ahead before you get there. FUEL, CHARGING AND YOUR CAR One button shows the fuel stations you can still reach on the range you have left, with prices, sorted by how little you leave your route. Driving electric? RadarIO plans the charging stops the trip actually needs — which chargers, which socket, how long at each. If the trip cannot be made, it tells you where you would run out. My Car keeps an odometer that updates itself as you drive, service reminders by date or mileage, and a fuel and expense log. It also remembers where you parked, without you pressing anything.

Great Circle Map
Read full descriptionHide full description
A globe you can turn in any direction, including straight over the poles. Great circle routes cross the poles, so we built a globe that follows them there. Enter two airports and the shortest path between them is drawn on the Earth itself, with distance and bearing on every leg. A Globe With No Pole Clamp Most map apps clamp the view at the poles. North stays up, and the globe stops turning right where great circle routes go. Great Circle Map uses a quaternion arcball instead. Drag in any direction and the globe follows, straight over the North or South Pole. Drag along the outer edge and the view rolls, so any direction can face upward. Find Any Airport • Search the full OurAirports database by IATA code, ICAO code, or city name. • Enter two airports and the great circle between them is drawn with its distance. • Recent routes save automatically and recreate with one tap. Waypoints and Weather • Double-tap anywhere on the globe to drop a waypoint. Double-tap it again to delete it. • Add as many waypoints as you want. There is no limit. • Every waypoint shows current conditions, temperature, and wind direction and speed in knots, from Open-Meteo. Distance on Every Leg • Each leg carries a sliding distance label and its initial bearing. • A running total stays pinned at the top of the screen. • Units switch between kilometers, nautical miles, and statute miles. Choose Your Earth • NASA Blue Marble satellite imagery or Natural Earth relief. • Toggle borders, airports, labels, and the grid. • View the globe in perspective or orthographic projection. Share the Route • Create Map exports your route as a flat map projection image. • The map unrolls across the antimeridian, so polar routes render cleanly. Privacy There are no analytics and no tracking. Weather requests send only waypoint coordinates to Open-Meteo.

Verdict
The clearest difference is price: RadarIO at Free against Great Circle Map's $0.99. Great Circle Map's advantage is in-app purchases (none vs 3) and update cadence (every 3 days vs every 6 weeks). On ads and device support there is nothing between them.
