Device Finder App vs Device Protocol Studio

Device Finder — the smart way to track down your lost Bluetooth gear in seconds. Misplaced your earbuds, headphones, speaker, smartwatch or a Bluetooth tag? Device Finder turns your iPhone into a powerful radar that scans the air around you, shows every nearby device and guides you straight to it — step by step. LIVE PROXIMITY TRACKING Pick a device and watch the live distance update in real time. The closer you get, the stronger the signal — with sound and haptic feedback that speeds up as you approach. "Hot or cold" has never been this easy. TREASURE-MAP MODE Our unique treasure-map view uses motion and signal data to draw a heat map of where your device most likely is. Just walk around and let the map point you to the spot. SEE EVERYTHING NEARBY • Instantly discover all Bluetooth devices around you • Clear signal strength and estimated distance for each one • Smart filters to find exactly what you're looking for • Save your favorite devices for one-tap tracking later WHY YOU'LL LOVE IT • Beautiful, modern dark interface • Fast, accurate, real-time scanning • Sound + haptics guidance — find things without even looking at the screen • Works great for earbuds, AirPods, speakers, smartwatches, trackers, headphones and more Whether it's slipped under the couch, buried in a bag or left in another room, Device Finder helps you get it back fast.

Device Protocol Studio (DPS) is a professional communication, protocol development, and testing toolkit built for embedded developers, firmware engineers, hardware engineers, and IoT developers. Connect to real hardware, simulate virtual devices, design custom protocols, monitor live data, and build repeatable test workflows — all from your iPhone. SUPPORTED COMMUNICATION • Bluetooth Low Energy (BLE) • TCP Client / Server • UDP • MQTT • WebSocket • HTTP / REST • CoAP DEVICE COMMUNICATION Connect to real devices and inspect communication in real time. • BLE scanning and connection • GATT service and characteristic exploration • Read, Write, and Notify operations • Dynamic RX / TX characteristic binding • TCP, UDP, MQTT, WebSocket, HTTP, and CoAP communication • Real-time terminal with ASCII, text, and binary workflows REAL-TIME DATA & PLOTTING Turn incoming device data into live engineering telemetry. • Multi-channel real-time plotting • Live CSV / ASCII data monitoring • High-speed data updates • Session logging and data export • Real-time RX / TX monitoring PROTOCOL DESIGNER Build and test your own communication protocols directly on your device. • Custom packet field definitions • Header and footer fields • Length and opcode fields • Payload configuration • CRC and checksum support • Custom field ordering • Reusable protocol presets VIRTUAL DEVICES Test communication workflows even when physical hardware is not available. • Built-in virtual device environment • BLE virtual device testing • TCP / UDP virtual communication • Simulated sensor data • Rapid protocol and UI verification TEST STUDIO Create repeatable communication tests for device and protocol development. • Command and response testing • Expected-response validation • Automated test sequences • Timeout and failure detection • Reusable test scenarios BUILT FOR ENGINEERS DPS is designed to reduce the number of separate tools needed during embedded and IoT development. Use one workspace to connect, inspect, design, simulate, plot, log, and test your device communication. PRIVACY-FIRST Your engineering data stays under your control. DPS is designed around local workflows without requiring external cloud synchronization for core development and testing. Whether you are debugging a BLE peripheral, testing a TCP device, designing a binary protocol, monitoring sensor telemetry, or validating command/response behavior, Device Protocol Studio gives you a portable engineering workspace directly on your iPhone.
