cmplx - Life Tracker & AI

Life is complex. Track it anyway.

cmplx is a personal tracking system for people who are genuinely curious about themselves. Log anything that matters — coffee intake, mood, sleep, pain levels, pages read, hours worked, current city — then let AI make sense of it all.

The point isn't the tracking. It's what you discover.

You might think you drink enough water. Your data might disagree. You might never have noticed that every time you worked from home, you slept better. Or that your worst reading weeks all followed poor sleep. cmplx surfaces these connections so you don't have to.

TRACK ANYTHING
Boolean (did it / didn't), numeric (how much), or text (what happened). Not just habits — anything you want data on.

ASK YOUR DATA
AI Insights lets you ask natural questions: "When do I sleep best?", "Does caffeine affect my mood?", "How many pages did I read this year?" Your history answers.

YOUR ROUTINES, YOUR RULES
Group trackers by morning, evening, or any routine. Set your own frequency. Start and end dates. Track at your pace, not the app's.

SYNC ACROSS DEVICES
Sign in and your data follows you across all your devices automatically.

FREE, FOREVER
No ads. No data selling. Core tracking is free, always.
