Level up your real life.
Tasks, habits and focus – with XP, levels and rewards.
CORTEX turns your to-do list, habits, focus timer and day plan into a game you actually want to play: finish tasks, earn XP, level up your character and spend credits on rewards you choose. Freelancers get time tracking and reports on top.
You do it all yourself.
Five tools, zero overview.
Tasks in one app, invoices in Word, time nowhere, finances only in your head. The result? You lose time, focus and energy — and by evening you have no idea where the day went.
App-switching all day
Tasks, calendar, invoicing, notes — each somewhere else. Half the work is just searching.Invoicing by hand
Invoices made manually, numbers looked up, payment references tracked. A pointless time sink.No overview of time or money
You don't know what actually makes you money, how many hours went where, or what to bill.
Direction first.
Then daily steps.
Break big goals into manageable steps and connect them to daily tasks. Keep your "why" in sight on the Vision Board and think projects through in Mind Maps.
- Goals with progress — see how close you are, not just a wishlist.
- Vision Board — your dreams and direction always in view.
- Mind Maps — plan a project before you dive in.
Wake up knowing
what to work on.
Pick a few priorities for the day, start the timer and focus on one thing. Cortex builds your day plan and watches deadlines, so nothing slips.
- One-click day plan — the system schedules your tasks for you.
- Focus timer — track time right on the task, no side notes.
- List and calendar — tasks grouped by day, drag & drop in the calendar.
An invoice done
in 30 seconds.
Create a professional invoice, download the PDF and send it to your client. Numbers, payment references and your client database are handled for you — and you instantly see who paid and who owes.
- Invoices + PDF — ready to send in moments.
- Client database — contacts, IDs and history in one place.
- Payment overview — paid / unpaid at a glance.
Measure what
work really takes.
Start a timer on recurring work and Cortex tells you how many hours went where. Finally you have data for invoicing and proof of what pays off and what doesn't.
- Reusable timers — start work on a project with one click.
- Time reports — by week, project or client.
- Billing data — charge for what you actually worked.
Reward now,
not a year from now.
Your brain loves small wins. Every finished task earns XP and credits, you level up and unlock rewards. Exactly the feedback that keeps you going even on the days you don't feel like it.
