Don't Buy a Focus Cube (Ours Included) Until You Run These Three Checks
I mean the title. Focus cubes are having a moment, your feed is full of them, and most of them will end up in a drawer by March. I'd rather you buy the right one once, even if it isn't ours. So before you spend a dollar with us or anyone, run these three checks. They take two minutes, and they work on every cube in your feed, including ours.

Day 31, for most focus gadgets. The checks below predict whether yours ends up here.
Check one: where does the start button actually live?
Plenty of cubes advertise "smart" features that quietly mean an app. Pairing, an account, a companion dashboard, firmware updates. Read the listing and look for the words "app" or "sign up." Here's why it matters: the entire point of a physical timer is moving the act of starting out of your phone. A cube that needs an app to set up, sync, or review your stats has moved the start button right back inside the thing you were escaping. Research on phone presence is clear that the device on your desk taxes attention even when it's off. A timer that keeps sending you back to it defeats itself.
Run it on us: FlipTimer™ has no app, no account, and no pairing. Take it out of the box, flip it, and it's running. That's the whole setup.

No pairing screen exists. This is the whole setup.
Check two: preset faces, or dial-your-own?
Some timers make you choose a duration every single session, with a dial, buttons, or a slider. That sounds like flexibility. In practice it's a decision, and decisions at start time are exactly what tired brains use to stall. There's a reason focus research keeps landing on pre-decided plans: deciding in advance, once, beats negotiating with yourself nightly. Look for fixed faces with sensible numbers, and check what the numbers are. You want a short default a tired brain will say yes to, a long block for hard work, a real break, and a small one for getting unstuck.
Run it on us: four faces, chosen on purpose: 25, 5, 50, 10. Flip the face you want up. No menu, no negotiation.

Four numbers, chosen once, so you never negotiate at 9 PM.
Check three: what happens on day 31?
This is the check that predicts the drawer. A timer is hardware; sticking with it is a method, and most cubes ship without one. Ask two questions of any listing. First, is there a real guarantee, with a number of days on it, so the risk of trying sits with them and not you? Second, does anything in the box teach you what to do when a week falls apart? Because a week will fall apart, and the tools that survive it are the ones with a plan for it.
Run it on us: a 30-day money-back guarantee and a 1-year warranty, in writing. And the system exists: the Flip Method™ playbook has a play for the night before an exam, the week after a bad week, and the evening you can't start, plus printable session sheets. The research behind all of it is cited, by journal, on our research page.
If we failed your checks, don't buy
Simple as that. If another cube passes all three and you like it better, buy that one and use it well. We built TurnCube because we couldn't find one that passed. If that's still true when you finish checking, the button below is waiting, and the 30 days start when the box arrives.
