Silent Proof: Focus Tracker

Prove your focus with verifiable proof.
Silent Proof is the first app that creates tamper-evident proof of your phone non-usage during focus sessions. Whether you’re studying, working, or in a digital detox, you can show others—or yourself—that you stayed off your phone.
How it works
Create a focus session, lock your screen within 10 seconds, and keep it locked until the session ends. Silent Proof monitors your screen lock state and app usage in real time. When you’re done, you get a verifiable proof report with cryptographic hashing and device binding—so it can’t be faked.
Verifiable proof
Tamper-evident reports with SHA-256 cryptographic hashing
Device-specific binding for authenticity
Export as shareable PNG cards or detailed PDF reports (Pro)
Full session metadata, including any violations and timestamps
Analytics and insights
Track daily and weekly silent minutes
View your longest clean session streak
Heatmap of your focus patterns over time
Dashboard, Activity, and Insights tabs for a clear overview
Smart violation detection
The app records screen unlocks, app switches, and service interruptions during a session. Every violation is timestamped so your proof reflects exactly what happened.
Privacy-first
All data stays on your device. No cloud sync, no external servers. Your focus data is stored locally and protected by cryptographic hashing.
Free and Pro
Free: 3 focus sessions per day, PNG export
Pro: Unlimited sessions and PDF export
Note: Silent Proof monitors your phone usage to generate proof. It does not block apps or restrict access—it only records activity to create verifiable proof of focus time.
