SOS Ring

Force ringtone for VIP contacts even in Silent/DND mode
New in version 1.0.1
Listing update:
- Added app icon and phone screenshots to the F-Droid listing
No functional changes.
SOS Ring forces your phone to ring at full volume when you receive a call from a VIP contact, even if your phone is in Silent, Vibrate, or Do Not Disturb mode.

Perfect for families where someone always keeps their phone on silent but needs to be reachable in emergencies.

HOW IT WORKS:
• Add your VIP contacts (family, partner, etc.)
• Enable the monitoring service
• When a VIP contact calls, SOS Ring overrides Silent/DND mode, plays the ringtone at your chosen volume (50-100%), and vibrates
• After the call ends (answered, missed, or rejected), your phone is restored to its original state — silent mode, DND, volumes, everything

WHY THIS APP EXISTS:
Android 14+ removed per-contact DND exceptions. No built-in way exists to let specific contacts bypass silent mode. Google restricts READ_CALL_LOG on the Play Store, so this type of app can't be published there. SOS Ring is free, open source, and works where others can't.

FEATURES:
• Pick VIP contacts from your phonebook or enter manually
• Configurable override volume (50-100%)
• Works in Silent, Vibrate, AND Do Not Disturb mode
• Full state restore after call (including alarm volume)
• Survives phone reboots (auto-start)
• Minimal battery usage (event-driven, no polling)
• Dark mode support
• No ads, no tracking, no internet required

PERMISSIONS EXPLAINED:
• Phone State & Call Log: detect incoming calls and identify the caller
• Contacts: pick VIP contacts from your phonebook
• Do Not Disturb access: override DND when a VIP calls
• Notifications: show a small persistent notification while monitoring
