Silent Proof

Prove your focus! Create tamper-evident proof of phone non-usage in sessions.

Prove Your Focus with Verifiable Proof

Silent Proof creates tamper-evident, cryptographically verified proof of your phone non-usage during focus sessions. Whether you're studying, meditating, working, or practicing digital wellness, Silent Proof provides verifiable evidence that you maintained uninterrupted focus time.

How It Works

Create custom focus sessions with personalized labels and durations. Once you start a session, Silent Proof monitors your device's screen lock state and app usage in real-time. Lock your screen within 10 seconds to begin, and keep it locked to maintain a clean session. The app automatically detects any interruptions—screen unlocks, app switches, or service interruptions—and records them with precise timestamps.

Verifiable Proof Generation

Every focus session generates a cryptographically secure proof report with SHA-256 hashing, device binding, complete metadata (start/end times, duration, violations, integrity status), and export options (PNG cards free, PDF certificates Pro).

Smart Violation Detection

Silent Proof tracks screen unlocks, foreground app changes, service interruptions, device reboots, and records all violations with precise timestamps.

Analytics & Insights

Track your focus journey with daily and weekly stats, streak tracking, activity pattern visualizations, and complete session history with detailed violation records.

Free & Pro Tiers

Free: 3 sessions/day, PNG export, full analytics, complete history, all core features. Pro: Unlimited sessions, PDF export, all free features, priority support.

Privacy & Security First

100% local storage—all data on your device only. No cloud sync, no external servers, no data sharing with third parties. Cryptographic security ensures tamper-resistant proof certificates. You control what you export and share.

Beautiful Design

Modern Material Design 3 interface with dark & light themes, smooth animations, and intuitive navigation.

Requirements & Setup

Android 5.0+ required. Grant Usage Access permission and disable battery optimization for best results. Getting started: Install, grant permissions, create session, lock screen within 10 seconds, keep locked, view and export proof.

Important Notes

Silent Proof monitors but does NOT block apps. It only tracks activity during active sessions to generate verifiable proof. Usage Access permission is required to detect app changes during sessions. We only monitor package names during active focus sessions, not general usage.

Perfect For

Students, professionals, digital wellness enthusiasts, meditation practitioners, accountability partners, and anyone who wants verifiable proof of phone-free time.

Why Silent Proof?

Unlike apps that block distractions, Silent Proof provides verifiable, tamper-evident proof with cryptographic hashing and device binding. Your proof certificates are authentic and cannot be manipulated.

Technical Details

Uses Android KeyguardManager for screen state, UsageStatsManager for app monitoring, foreground service for continuous monitoring, SHA-256 hashing for proof integrity, device-specific binding, and local SQLite storage.

What Gets Monitored

During active sessions only: screen lock/unlock events, foreground app package names, service interruptions, device reboots. We do NOT monitor general app usage, app content, personal information, or location data.
