Understand where your time went and reduce distractions.

AI Time and Distraction Tracking

Gamified Productivity with the Mini Timer

See your productivity counting up live. No annoying and rule-based blockers. Sometimes you have to use distracting websites for work. Cronus understands what you are doing and categorizes your work accordingly.

I thought I was working 12-hour days, but Cronus showed me the reality. After a gym session and lunch, I was surprised to see three hours had passed.

I used Rize for a while but found it overwhelming and slow. Tried out Cronus and instantly fell in love with the simplicity and speed. That’s how productivity tracking should feel like.

Cronus is refreshingly simple. Open it, and you instantly see where your time is going. It's easy to classify activities on the fly without getting bogged down in categories. The simplest and most effective time tracker I've used.

HUGE fan so far! Funnily enough, I had a 'holy shit, this product is going to be in my life for a long time' moment when I saw everything I'd done laid out in the calendar view.

It used to take me ~2 hours each week to figure out: 1) how many hours I worked, and 2) how much time I was distracted/on social media. Cronus automates it and makes it 10x more accurate.

Cronus showed me exactly how much time I wasted on Hacker News and other distractions. It’s also great for tracking work vs. learning.

As a PM, context switching is constant — meetings, docs, Slack, planning. Cronus helps me protect focus time and make better use of deep work hours.
