Works on Fire HD 8

• + Microphone sound level and spectrum
• + Nearby Wi-Fi network scan
• + Wi-Fi-based location

Good to know

• – NFC and Bluetooth bays are visible but can't scan in the Android app: Android's in-app browser (WebView) doesn't give websites those radios. They scan on majorturkey.app in Chrome (NFC on Android phones only). The NFC paste decoders still work in the app
• – Compass and gyroscope readings only on devices that have those sensors (not Fire HD 8)
• – Needs an internet connection every time you use it

Your purchase also unlocks APOGEE on the web at majorturkey.app: open it in any browser and enter your checkout email. The Android app adds the Wi-Fi scan, light sensor on Fire tablets, screen wake during a survey, and exports saved straight to your device.
