  "account": "The author recounts the experience of a high-pitched ringtone interrupting a silent environment, which inspired the creation of Muffle, an automation tool for managing phone sound profiles. The challenge was finding a balance between accurate location tracking and battery life on Android devices. Android's GeofencingClient allows for location-based triggers, but it optimizes for battery life by batching location updates, which can lead to delayed triggers or inaccurate transitions. To address this, the author implemented a custom state-buffer system to buffer state changes and prevent rapid toggling of sound profiles. The author also had to contend with Android's aggressive battery management policies, such as Doze mode, which could kill background services. To counteract this, the author used a ForegroundService with a persistent notification to signal to the OS that the app is performing a critical user-facing task, thereby maintaining higher priority. The author emphasizes the importance of respecting Android's constraints and designing architecture around them, rather than fighting them. This means using JobScheduler or WorkManager for non-time-sensitive tasks, maintaining local state for app resilience after reboots, and focusing on creating an invisible automation experience rather than one that adds complexity.",
  "summary": "It was the second rakat of Maghrib prayer, the quietest moment of my evening, when a jarring, high-pitched ringtone shattered the silence of the room. It wasn't my phone, but the sound was loud enough to break the focus of everyone standing in the row. I felt that familiar, sinking pit in my stomach. We have all been there: a meeting at work, a medical checkup, or a silent lecture where our…",
