Opening hook
The silence in the lecture hall was absolute, punctuated only by the professor’s rhythmic pacing. I was deep into a complex algorithm proof when a sudden, jarring marimba riff cut through the room. It was my phone, tucked away in my bag, blaring at maximum volume. I felt the collective eyes of two hundred students turn toward me as I frantically scrambled to mute the device. That moment of visceral embarrassment stayed with me long after I left the room, leaving me wondering why my phone couldn't simply understand where it was and adjust accordingly.
The problem
We live in a world of context-dependent behavior. When I am at a medical clinic, in a mosque, or sitting in a high-stakes meeting, I need my device to reflect the social environment. Yet, the burden of managing this state is entirely manual. Android offers Do Not Disturb and volume profiles, but toggling these based on location or time requires active intervention. If I forget to silence my phone, I risk disruption. If I remember to silence it but forget to restore the volume later, I miss important calls or notifications for the rest of the day.
I searched for a solution, but most existing apps were heavy, battery-draining monsters that required constant GPS polling or cloud-based server pings. I wanted something that felt like a native OS feature—something that sat quietly in the background, respected the hardware limitations of the device, and actually worked reliably without turning my phone into a space heater. The friction wasn't just about sound; it was about the cognitive load of constantly monitoring my own device state throughout the day.
