Hi Product Hunt! I'm the solo developer behind Signal Hound. I built this app out of pure frustration. Whether I was working remotely, downloading large files, or gaming, my WiFi would occasionally drop silently. I wouldn't realize the connection was dead until 10 minutes later when a download failed or a call disconnected. I wanted an active guardian for my network. Enter Signal Hound. 🐕📶 It’s a background WiFi monitor that acts as a guard dog. The exact second your internet drops, it throws a "Red Alert" Heads-Up notification and blasts a custom alarm to let you know. To keep it from being just another boring utility app, I gamified the experience: The Stamina System: Your guard dog needs stamina to stay awake in the background. You can stack up to 7 days of monitoring by "feeding" him, or upgrade to Pro for infinite stamina. Smart UI: It tracks your network history, logs your uptime, and gives you a visual representation of your connection health. The Technical Journey 🛠️ Building this entirely in React Native and Expo was a massive challenge, especially navigating Google's strict new Android 14 policies around background tasks and USE_FULL_SCREEN_INTENT. After getting initially rejected by Google Play for trying to build a native full-screen wake-up, I had to pivot to a high-priority Heads-Up notification system paired with Expo's local authentication to secure the dismiss button. It was a brutal learning curve, but the final result is incredibly lightweight and battery-friendly. I would absolutely love your feedback on the gamified UI, the stamina loop, or any questions about building background-heavy utility apps with Expo! Thanks for checking it out! 🚀
