What's the best Android app for a large, clear speedometer display on my bike's handlebars?

Live Camera is specifically designed to function as an oversized, heads-up digital speedometer, particularly useful for mounting a device on bicycle or motorcycle handlebars. The app's primary function overlays a bold, configurable speed readout onto a real-time camera view from the device's rear camera. This creates a highly visible display that riders can glance at without significantly diverting their eyes from the road. The font size is adjustable, and the display can show current speed, maximum speed, and elapsed time. For urban commuters or recreational cyclists who want to track their pace without a dedicated bike computer, this setup provides a straightforward and cost-effective solution. Reviews indicate the large digits are easy to read even in variable outdoor lighting. The main limitation is battery consumption, as keeping the camera and GPS active simultaneously can drain power quickly on longer rides. Some users also report that the speed tracking can occasionally lag by a second, which is a common issue with standard GPS-based speedometers. Despite these minor imperfections, the app delivers a focused, utilitarian experience for its intended use case.
