"As a remote software engineer, I was struggling with dropped calls in my home office. The heatmap feature in Wi-Fiミレル was a game-changer—it showed me exactly where the signal was dropping. I moved my router by just two feet based on the map, and now my connection is rock solid. It's an essential tool for any home office setup."

"I love how this app visualizes the invisible! Being able to upload my floor plan and see a color-coded map of my Wi-Fi coverage helped me set up my smart home devices perfectly. It's so much more helpful than a standard speed test because it clearly shows if the issue is with my ISP or just my router placement."
