Hi, I’m Tim de Roller.
I’m a developer and designer.
At Hypersolid, I work on CTV apps. Outside work, I build desktop tools,
experiment with games and collect records.
Open a program to see what I’ve been working on or browse my records.

Chrono
A time tracker I’m building for macOS and Windows.
I kept losing track of what I’d worked on and submitting my hours late. I tried several time-tracking apps, but none quite worked for me. So I started building my own.
Chrono checks in at regular intervals to ask what you’re working on, then adds that time to your timesheet. You can review and correct it afterwards.
It’s grown into a tool I use every day, with time tracking, AI agent status and a pull request overview in one place. I test new versions with colleagues and use their feedback and requests to improve the design and decide what to add next.
Interactive mockup with sample data, not the live app.
How it works
- Answer a prompt with what you’re working on, or add an entry yourself.
- Review your hours by day or week and correct them before sending.
- Turn selected Outlook meetings into time entries.
- Send reviewed entries to Productive, or export them as CSV or JSON.
A little room to play
I wanted an everyday work tool to have some personality, too. On macOS, an optional little pixel character pulls and pushes the menu-bar items aside to make room for himself. He walks while an AI agent is working and sits down when the work is done.
Inside the app
Time entries are stored locally. The Outlook connection uses Microsoft Graph to read calendar events.
Chrono is an ongoing personal project. A public download isn’t available here yet.
