FocusSpark: Smart Focus Sessions

Session-based Pomodoro + intelligent site blocker for deep work.

Features & Capabilities

Overview

The ultimate session-based Pomodoro timer and intelligent website blocker. Take back your time, block distractions, and build healthy focus habits. No willpower required.

🛡️ PRIVACY-FIRST: Zero Tracking, 100% Local Data.

FocusSpark turns every focus session into a complete deep-work ritual: a Pomodoro timer that starts your work, a smart site blocker that defends your attention, and a personal analytics suite that tracks your progress,all running securely on your device.

No friction. No nagging. No logins. Just deep work.

⚡ Why FocusSpark is Different

Most productivity timers just count down. FocusSpark protects your time. The moment a session starts, distracting sites are blocked instantly at the network layer, a beautiful floating timer follows you across tabs, and your progress is tracked silently in the background. Stop the session, and everything releases automatically.

✨ Core Features

🍅 Customizable Pomodoro Timers: Run classic Pomodoro 25, Deep 52, Deep 90, or build your own custom work/break cycles. Pause, skip breaks, or schedule sessions to auto-start every weekday morning.

🛑 Intelligent Site Blocking: Built on lightning-fast native network engines. Choose Blacklist or Whitelist modes, let FocusSpark suggest sites to block based on local browsing patterns, or set daily time caps on specific sites.

🛟 The "2-Minute Peek": Willpower is finite. If you genuinely need to grab a link from a blocked site, use Peek Mode for 2 minutes without abandoning your entire session.

💚 Healthy Focus Habits (New!): Avoid burnout with 20-20-20 eye strain reminders, hydration nudges, guided box-breathing breaks, and "Wind-down hours" that auto-block distractions in the evening.

📊 Deep-Dive Analytics: Understand exactly when you do your best work. View 7×24 hour-of-week heatmaps, week-over-week deltas, top-10 distraction heatmaps, and your "time-to-first-focus" morning median.

🏆 Gamified Motivation: Unlock 23 built-in achievements (plus 3 secret ones!), define your own custom goals, and maintain momentum with automatic streak freezes, custom motivational quotes, and 30-day milestone ladders.

🧠 Smart Suggestions (Opt-In): Wondering where your time goes? FocusSpark can optionally analyze your recent browsing during work hours to suggest distracting sites you forgot to block.

⚡ Polished & Out of Your Way: Features an AMOLED true-black theme, an optional New Tab dashboard, idle detection that auto-pauses when you step away, and auto-tab grouping to keep your workspace uncluttered.

🔒 100% Privacy by Design

FocusSpark is engineered with strict security standards. Your data belongs to you. Zero Data Collection: All data lives purely in your browser's local storage. Nothing is sent to a server. Ever.

No Accounts: No sign-ups, no emails, no tracking pixels. Locally Processed: History analysis for smart site suggestions is completely opt-in and processed 100% on-device.

Transparent Permissions: Every permission requested is fully documented and justified.

⌨️ Pro-Tips

Instantly control your timer with built-in keyboard shortcuts for start, pause, resume, and stop. Jot down session notes directly in the app to reflect on your deep-work output later.

Export your analytics as a CSV, PDF, or share your Streak Calendar as a PNG.

💸 Free, Forever

FocusSpark has no paid tier, no upsells, and no ads. It exists because focused work is hard enough,your tools shouldn't make it harder.
