A free, open-source productivity tool built by the community, for the community.
We live in an age of engineered distraction. Every app is designed to capture and monetize your attention.
TimeMark exists as an alternative.
We believe that understanding your digital habits is a fundamental right, not a premium feature. That awareness should empower, not shame.
Our mission is simple: give everyone the tools to understand their digital life, make informed choices, and work with their brain's natural rhythms—not against them.
TimeMark began as a personal project. I tried commercial screen time apps, but they were either too expensive, privacy-invasive, or treated me like a child to be controlled.
What started as a personal tool has grown into a full-featured productivity suite. TimeMark proves that powerful tools can be built without surveillance.
The principles that guide every line of code we write.
Your usage data reveals intimate details about your life. That's why TimeMark stores everything locally on your device.
Your data never leaves your computer.
Closed-source productivity apps are black boxes. TimeMark is fully open-source.
Open-source isn't just a development model—it's an ethical commitment to transparency.
Productivity tools shouldn't be gatekept behind paywalls. TimeMark will always be 100% free.
Money will never be a barrier to digital wellness.
You're an adult. You don't need an app to parent you. TimeMark provides information and reminders—not restrictions.
The goal is awareness and intentionality, not control.
TimeMark isn't built by a corporation optimizing for profits. It's built by users, for users.
The roadmap reflects what users actually need, not what investors want to see.
Carefully chosen technologies prioritizing performance and reliability.
Google's UI toolkit for beautiful, native interfaces with high performance.
Modern, type-safe language optimized for UI development and stability.
Lightning-fast, local NoSQL database. No servers, complete privacy.
Direct integration for accurate, low-impact foreground tracking.
TimeMark is actively developed. Here's where we're going.
From personal project to global tool.
I realized I was spending 10+ hours daily on my computer but couldn't answer: 'How much was productive?' Existing tools were invasive or expensive.
Built a basic Flutter app that tracked foreground applications. No analytics yet, but it worked.
Published on GitHub. Got first star from a stranger. Realized there was real interest in privacy-first tracking.
Released on Store for easier installation. First bug reports from real users began rolling in.
10,000+ downloads. Contributors from 15 countries. TimeMark is now a community effort.
Used by thousands worldwide. Still 100% free. Still committed to privacy. Still improving everyday.
Built by developer for community.
We don't collect your data. Period.
All data is stored locally in your Documents/ folder. You can verify this by auditing our open-source code.
TimeMark is free and always will be. We don't offer premium features because financial status shouldn't dictate digital wellness.
"Let's build a better digital future—together."
