About CORTEX
CORTEX is a gamified productivity app – tasks, a one-click day plan, focus timers, goals and habits that earn you XP and levels. It is built by Daniel Gavalec, free for everyone, and funded by voluntary supporters.
- CORTEX is founded and developed by Daniel Gavalec, who also writes the guides on this site.
- Every feature is free for everyone – no ads, no paid tier, no selling of data.
- Servers and development are funded by voluntary supporters; support unlocks nothing.
- Our guides cite sources you can check, show the last update date and name CORTEX’s weak spots too.
Who builds CORTEX
I’m Daniel Gavalec, the founder and developer of CORTEX, and the author of the productivity guides on this site.
CORTEX is an independent project from the Czech Republic with no investors. The only thing that matters is whether it actually helps you get things done and build habits – not how many ads it can show.
You can reach me at info@getcortex.cz. I read every message, and user ideas often go straight into the app.
Why CORTEX is free
CORTEX is free for everyone, with every feature. There is no paid tier, no ads, no limits on tasks, goals or habits, and we don’t sell your data.
Servers and development are funded by voluntary supporters – people who like CORTEX chip in about a dollar a month. Support unlocks nothing; you get everything without it. It’s a thank-you that keeps the project independent.
How we write
Our guides exist to help you work better – with or without CORTEX. We follow these rules:
- Sources: research claims are backed by peer-reviewed studies or official sources, linked at the end of each guide. Where the evidence is mixed, we say so.
- No made-up reviews or numbers: no invented user quotes, ratings or statistics.
- Fair comparisons: competitor prices and limits are dated, and we say when another app is the better choice. Nobody pays for placement.
- CORTEX’s weak spots: we say plainly what CORTEX doesn’t do (for example Kanban or Google Calendar sync).
- Freshness: every guide shows its last update date, and we review guides regularly.
- Tools: we use AI tools for research and drafting. Facts, sources and the final text are always checked, and we take responsibility for them.
- Health topics: ADHD, sleep or burnout are covered in general terms only – not medical advice.
