Roam: GPS Speedometer

Roam shows one thing: your current GPS speed, in big digits on a pure black screen, with nothing else fighting for your attention. It exists because leaving a navigation app open for hours just to watch your speed is rough on OLED screens. A bright, static interface slowly burns itself into the panel. Roam is designed from the ground up to leave no trace on yours. How it protects your screen: * The readout moves. Every few minutes (1 to 10, your choice) the speed display glides to a new position, so no area of the panel carries the load for long. * Pure black background. On OLED, black pixels are switched off, so only the digits are lit. * Colour drift. The digit colour slowly shifts hue over time, so no single subpixel is driven hard at one fixed colour for hours. * Outline digits. An optional hollow digit style that lights a fraction of the pixels. * Brightness control. Dim the display from inside the app without touching your system settings. The rest: * Current speed in km/h or mph, plus a session max. * The screen stays awake while the app is open. * No ads, no tracking, no network access at all. The only permission is location, used for GPS speed. * Tiny: the app is well under 100 KB. Roam is free and open source (AGPL-3.0). Source code and privacy details are linked below.
