The essential Bluetooth app for scanning and locating your smart devices from Apple, FitBit, Garmin, and many other companies. Scan and identify nearby devices. Locate devices by signal strength, heat map or direction finder. You can now find Fitbit and other Bluetooth devices that are paired with your iPhone. If the Bluetooth device is paired with another iPhone, turn off Bluetooth on that iPhone. Blue Hound is always scanning for Bluetooth devices. When a device is detected, Blue Hound identifies it by name, maker and model when possible. It does this using a large database of smart recognizers that are updated automatically. Devices you find are uploaded to the cloud to help you search for them later. Blue Hound works great with Bluetooth tags. If you attach one to your keys, you can locate them within 100 feet or more even outdoors in high grass. Attach one to your drone and you will be able to find it if it lands unexpectedly. Scanning for Bluetooth devices can be a fun outdoor activity. Take Blue Hound out for a walk. Enable Power Saver Mode for Blue Hound in Settings and put your iPhone in your pocket upside down. The screen will go dark and the app will enter power saver mode. If you wish, Blue Hound can even bark to alert you when a new device is found.

Scheme O is a tactical planning tool designed to help leaders rapidly build clear mission graphics and planning products. Instead of spending hours manually drawing terrain analysis and overlays, Scheme O allows users to construct tactical planning geometries in seconds. Built around real problems leaders encounter during mission planning, the platform focuses on speed, clarity, and predictable results. Key Features: Rapid Geometry Creation - Build planning geometries instantly using real weapon systems or custom parameters. Flexible Map Drawing - Create shapes, lines, and overlays that match the complexity of real terrain instead of forcing planning into rigid formats. Route Planning with Checkpoints - Plan routes with checkpoints, pace estimates, and time calculations to better understand movement across the battlefield. Integrated Planning Tools - Quickly place friendly and enemy positions, generate graphics reference grids (GRGs), and build planning overlays directly on the map. Close Air Support Planning -Integrate CAS considerations directly into the planning environment. Weather Integration - Pull weather data for specific days to support planning and analysis. Data Matrix Output - Automatically consolidate planning data into structured outputs that can be easily copied into orders, briefs, or planning documents. 3D Recon - Assess the terrain and see how your plan will actually look on the ground. Scheme O helps leaders spend less time drawing graphics and more time thinking about the fight.
