About
Most habit apps want you to track everything. Crux wants you to finish something.
ONE GOAL AT A TIME
Pick one goal, a habit to build, a project to finish, anything you want to make real. Crux walks you through five quick questions: what you're doing, why it matters, what you'll actually do, and how you'll know you're done.
Then it gets out of your way, except for one thing.
CHECK-INS THAT KEEP YOU HONEST
Crux sends a simple nudge: "Did you make progress?" Answer right from the notification. Stay consistent and the check-ins space out. Go quiet, and Crux leans back in, without being annoying about it.
EVERYTHING IN ONE PLACE
• Your goal, your why, and your action items, all in one view
• A streak counter or progress bar, depending on how you're measuring success
• A running history of every check-in
WHEN YOU'RE DONE, CELEBRATE
Hit your target (or decide you're done) and Crux marks the moment, then nudges you to take a breather before picking your next goal.
NO ACCOUNT. NO CLOUD. NO NOISE.
Crux runs entirely on your device. No sign-up, no tracking, no ads. Just you and the one thing you're trying to do.
If you've ever set up a dozen habits and abandoned all of them by Thursday, Crux is built differently. One goal. Real focus. Until it's done.
