Obsidian Utility

Obsidian Utility is a multi-purpose pocket toolkit with a sleek dark interface, designed for comfortable use in any environment. Combine essential everyday tools into one lightweight app.

🔦 FLASHLIGHT
Instantly turn your phone's camera flash on or off with a single tap. Adjust brightness level using the built-in slider to suit your needs. The flashlight can be set to automatically turn on when the app launches, and optionally stay active even when the app is in the background.

🆘 SOS EMERGENCY SIGNAL
Activate the standard international SOS morse signal (··· ——— ···) with one tap. Your phone's flashlight will automatically flash the SOS pattern repeatedly, making it useful in emergency or low-visibility situations.

📡 MORSE CODE TRANSMITTER
Type any message and transmit it as morse code through your phone's flashlight. The app converts letters and numbers into dots and dashes following the international morse code standard. A real-time morse code preview shows the encoded signal before transmission. Includes a signal legend for learning morse code basics.

🧭 DIGITAL COMPASS
A real-time digital compass powered by your device's built-in magnetic and accelerometer sensors. Displays current bearing in degrees with cardinal direction indicators (N, NE, E, SE, S, SW, W, NW). Includes a dedicated compass calibration tool — move your device in a figure-8 pattern to improve sensor accuracy. The calibration screen shows magnetic field strength and sensor accuracy status in real time.

🎨 COLOR LIGHT
Turn your phone screen into a colored light source. Choose from multiple preset colors including white, red, blue, green, magenta, and yellow. Useful as a soft ambient light, for photography lighting, or signaling purposes.

Whether you need a reliable flashlight during a power outage, a compass for outdoor navigation, an SOS signal for emergencies, or a morse code transmitter for fun and learning — Obsidian Utility has you covered in one simple app.
