SmartFind is a find-my-phone app triggered by SMS from designated contacts.
When a trusted contact sends an SMS containing your chosen keyword, SmartFind sounds a loud alarm — even if your phone is on silent or Do Not Disturb mode.
Features:
• Designated contacts — only people you trust can trigger the alarm
• Custom trigger keyword — choose your own secret word (default: FIND)
• Bypasses silent mode and Do Not Disturb — the alarm always sounds
• Biometric authentication — all settings changes require fingerprint or PIN
• Encrypted storage — contacts and settings secured with Android Keystore
• Cooldown protection — prevents alarm spam with configurable cooldown
• SMS spoof detection — validates SMS origin to prevent abuse
• Audit log — full history of alarm triggers and events
• Device admin — optional uninstall protection
• Battery-aware — adapts behavior based on power save mode
Privacy:
• Zero internet connections — operates entirely offline
• No analytics, no tracking, no cloud services
• All data stored locally on your device
• Phone numbers redacted in audit logs
Versions
Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
