S1Pro
Auto Mobile Silent App by Target Area & Range
S1Pro is an intelligent mobile automation application developed by ProDevOpz. It automatically switches your smartphone into Silent, Vibrate, or Do Not Disturb (DND) mode as soon as you enter designated target locations—such as mosques, temples, classrooms, offices, or hospitals—within your selected distance range, and seamlessly restores your normal ringtone volume the moment you step outside.
Silence Phone Where It Matters Most
Mosques, Temples, Churches & Gurudwaras. Avoid embarrassing ringtones during prayer times, sermons, and spiritual gatherings without manual intervention.
Classrooms, lecture halls, reading rooms, and exam centers. Keep phones disciplined during study hours and automatically unmute during campus breaks.
Intensive care units, doctor consultation chambers, and quiet wards where ringing phones disturb patients and medical operations.
Boardrooms, client pitches, and quiet open-office spaces. S1Pro ensures silence throughout business meetings and restores volume when heading home.
Intelligent Features of S1Pro
Target Area Pinning & Geofencing
Easily search or pin any location on the map—such as places of worship, educational campuses, hospitals, or conference rooms—as an active silent zone.
Adjustable Proximity Range & Radius
Set the exact perimeter radius (from 25 meters up to 2 kilometers) for each zone so your phone silences right when you enter the threshold.
Instant Auto Silent & DND Trigger
Switches your device immediately to Silent, Vibrate, or Do Not Disturb as soon as GPS or fused cell-tower coordinates enter the target radius.
Automatic Sound Restoration
Never miss an important call again. As soon as you step outside the target perimeter, S1Pro instantly restores your normal ringtone and alert volume.
Ultra-Low Battery Consumption
Engineered with intelligent background geofencing APIs and passive location listeners that consume less than 1% battery over a 24-hour cycle.
Time-Window & Day Filtering
Combine location with time rules. For instance, silence only during Friday congregational prayers, college lecture hours (9 AM - 4 PM), or office shifts.
How S1Pro Automates Your Sound Profile
Add Target Area & Range
Search any place on the map or save your current location. Set your desired boundary range (e.g. 50 meters for a mosque hall or 200 meters for a college campus).
Auto-Silent On Arrival
When your smartphone crosses into the defined target range, S1Pro quietly silences the ringer and notification alerts without any button presses.
Auto-Restore On Exit
The moment you leave the target perimeter, S1Pro automatically returns your phone back to your normal sound profile so you never miss an incoming call.
Engineered by ProDevOpz
S1Pro is engineered by ProDevOpz using native Android hardware APIs, fused location providers, hardware geofencing, and background Android WorkManager tasks. It runs 100% on-device: your private target locations and daily routines never leave your phone.
