📌 Notes

📡 The Radar and EMF Meter require a Magnetometer sensor. The SpiritBox works without it. Check your phone's tech specs to confirm sensor availability
📲 Compatible with Android 7.0 to 15
⚠️ This is a custom APK (sideload) installation. Never install APKs from untrusted sources! You can verify file integrity using the SHA256 checksum listed in the changelog below

⚠️ Important: Google Is Making Sideloading Harder

Unfortunately, Google has been tightening restrictions on installing apps outside the Play Store. Stricter sideloading rules may expand further in autumn 2026. Depending on your Android version and region, you may hit a 24-hour waiting period when installing APKs

There are two ways to deal with this:

• Method A — Developer Mode: Allows installation after a 24-hour wait
• Method B — ADB (Android Debug Bridge): Bypasses the waiting period entirely

---

📥 Standard Installation

1. Download the APK from this page
2. Go to Settings → Security (or Privacy → Install unknown apps on newer Android) and allow your file manager or browser to install from unknown sources
3. Open your Downloads folder and tap the APK file
4. Follow the on-screen prompts to finish installation

---

🧑‍💻 Method A — Developer Mode (24-hour wait)

If Google's enhanced protection blocks the install, enabling Developer Mode on your device will allow it — but only after a mandatory 24-hour wait from the first install attempt

1. Open Settings → About phone
2. Find Build number and tap it 7 times in a row. You may be asked for your PIN or fingerprint
3. Go to Settings → System → Developer options
4. Scroll down and enable Install via USB, or disable Enhanced security for unknown sources if that option is present on your device
5. Attempt to install the APK. If prompted about a 24-hour wait, confirm and try again the next day

⏱️ The 24-hour countdown starts the moment you attempt the install. You don't need to keep your screen on — just try again the next day

---

⚡ Method B — ADB Install (No Wait)

ADB (Android Debug Bridge) installs APKs directly from a PC or Mac, bypassing Google's enhanced protection and the 24-hour delay. You'll need a computer and a USB cable

Step 1 — Set up your computer

1. Download Android Platform Tools from developer.android.com and extract the ZIP to a folder (e.g. C:\adb\)
2. Windows: Hold Shift and right-click inside the folder → select "Open PowerShell window here"
   Mac/Linux: Open Terminal and navigate to the folder with cd ~/adb

Step 2 — Enable USB Debugging on your phone

1. Enable Developer Mode first (tap Build number 7 times — see Method A above)
2. Go to Settings → System → Developer options and enable USB debugging
3. Connect your phone to the computer with a USB cable
4. On your phone, tap Allow USB Debugging when prompted. Check "Always allow from this computer"

Step 3 — Install the APK

1. Copy the downloaded APK into your ADB folder
2. In your command window, run: adb devices — your device should appear. If it shows "unauthorized", check your phone and tap Allow
3. Install with: adb install ghosthunter.apk (replace the filename with the one you downloaded)
4. Wait for the Success message. The app is now installed! 🎉

💡 ADB completely bypasses any Google-imposed waiting period. It is the recommended method if the standard install is blocked on your device

🕵️ How to Use the App

1. Launch the app and grant access to the camera (photos) and microphone (EVP recording)
2. Walk around and investigate! If EMF readings seem erratic, shake the device or recalibrate the sensor
3. EVP recordings are saved to the "Ghosthunter" folder on internal storage. Photos appear in your Gallery

🧭 Sensor Calibration

Keep the phone away from metal objects, speakers, and other electronics — they cause false readings

• Check your sensor: Open the Phone (Dialer) app and enter the code *#0*#. Go to Sensor and look for Magnetometer readings
• Calibrate: Move your phone in a slow figure-eight motion several times
• Alternative: Open Google Maps → tap your blue location dot → select Calibrate Compass
