Gattwise: BLE Workbench

Gattwise is a private Bluetooth Low Energy workbench for developers, makers, and curious people. Scan what is nearby, decode what each device advertises, connect to inspect its GATT services, and save snapshots to compare later. Everything runs on your iPhone or iPad. SCAN - Start and stop scans yourself; nothing runs in the background - Live RSSI with a per-device signal history chart, median, spread, and signal quality - Search by name, identifier, company, or service, plus minimum-signal, named-only, connectable-only, and "hide unnamed Apple devices" filters - Sort by signal, name, first seen, or most recently seen DECODE - Company identifiers, advertised services, service data, Tx power, and connectable flag in plain language - Eddystone-UID, Eddystone-URL, and Eddystone-TLM frames (battery, temperature, uptime) - Rough distance estimates when a device advertises its power GATT EXPLORER - Connect on demand and browse services, characteristics, properties, and descriptors - Read values, write as hex, UTF-8 text, or a single byte (with or without response), and subscribe to notifications - Readable values for common characteristics such as battery level, heart rate, temperature, humidity, pressure, and device information strings - Timestamped session log you can export as CSV SNAPSHOTS - Save what is nearby with signal medians and advertisement data - Compare two snapshots: devices that appeared, disappeared, or changed (services, manufacturer bytes, service data, Tx power, signal beyond your threshold) - Export snapshots and comparisons as CSV, and back up or restore all snapshots as a JSON file OFFLINE TOOLKIT - Advertisement decoder for bytes pasted from any capture, including iBeacon frames - Byte converter: hex, UTF-8, little- and big-endian integers, Base64 - Searchable lookup of common company IDs, services, characteristics, and descriptors - Distance estimator with an adjustable path-loss exponent SAMPLE DEVICES No hardware nearby? Turn on sample devices to explore every screen with clearly labeled, app-generated sample data and a simulated GATT table. PRIVATE BY DEFAULT No account, ads, tracking, analytics, or network requests. Snapshots and logs stay on your device until you export them. ONE PURCHASE Everything is included. No subscription and no in-app purchases. WHAT iOS ALLOWS iOS gives apps a per-app device identifier, not the hardware address, and does not deliver iBeacon advertisements or Classic Bluetooth devices to Bluetooth LE scans. Gattwise shows only what CoreBluetooth exposes. Radio observations are not identity proof.
