Habit Stacking
Read full descriptionHide full description
Big goals fail because they start too big. Cubit starts with the moment after your coffee. Habit stacking is the one technique behind every routine that actually lasts: take a moment you already own (after coffee, after lunch, when you climb into bed) and attach a chain of tiny actions to it. Cubit is built around that single idea. You never track a lonely habit again; you run a stack, one block after another, and the anchor moment does the remembering for you. WHAT YOU GET โข Routines that run themselves: every stack hangs on a real anchor moment, so you stop relying on willpower and start relying on sequence. โข A first stack in under a minute: pick from 24 built-in micro-habits such as one push-up, box breathing, a gratitude note or phone face-down. โข Momentum you can see: check off each block and watch the progress ring close in real time, stack by stack. โข Streaks that mean something: current and best streaks per stack, plus a seven-day consistency score that tells you the truth about your week. โข A nudge at exactly the right moment: an optional daily reminder fires at each stack's anchor time, not at some random hour. โข Your own habit library: add any micro-habit with an icon and an estimated time, search it, and drop it into as many stacks as you like. PERFECT FOR โข Anyone who has downloaded a habit tracker before and quietly abandoned it by week three. โข Morning people and night owls building a ritual that fits their actual day. โข Readers of Atomic Habits and Tiny Habits who want the method, not another checklist. โข Busy parents, students and shift workers who only have two spare minutes at a time. WHY NOT JUST USE A HABIT TRACKER? A tracker gives you a grid of empty boxes and hopes you remember. Cubit gives each habit a home: a trigger, a place in the sequence, and a ring that fills as you move through it. Three tiny actions chained to one anchor beat one big resolution every time. PRIVATE BY DEFAULT No account. No sign-up. No sync servers. No analytics sent anywhere. Every stack, habit and check-off lives on your iPhone and nowhere else. The only permission Cubit ever asks for is notifications, and only if you switch on a reminder. FULL ACCESS Cubit is a premium app. Unlimited stacks and blocks, the full habit library, per-stack progress rings, streaks and reminders are unlocked with a Weekly or Yearly subscription. Pricing is shown in the app in your local currency before you confirm. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled at any time in your Apple ID settings. Build your first stack tonight: anchor it to "after dinner", add three blocks, and check them off before you sleep.
