What our users are saying
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.

Head of Growth at Runpod
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.
Leander Märkisch
Founder of Floy
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.
Koii Benvenutto
Product Manager at Trass Games
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.
Savannah Feder
Founder of Astral AI
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.
Moritz Wallawitsch
Founder of Cronus, ex. RemNote
Cronus showed me exactly how much time I wasted on Hacker News and other distractions. It’s also great for tracking work vs. learning.

Cronus has completely transformed how I manage my time by automatically tracking my work and distractions with impressive accuracy - really helped me getting more done.
Frederik Feldmeier

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.
Dominik Fink
Product Manager
I love having an overview of how much time I work on each one of my projects and Cronus does an amazing job at it. It also helps me stay focused, seeing the distraction timer pop up gets me back to work instantly.
