About

Zero Dark

Read full description

Zero Dark is the alarm clock you can't snooze your way out of. Stop the alarm and a wake mission opens. Do the sums, type your goal, shake your phone, walk the steps or scan the code you stuck in the kitchen. Walk away without finishing and it rings again three minutes later. EARN THE MORNING Every clean wake earns rank. Snoozes and missed alarms cost it. Seven ranks from Recruit to Commander, re-earned every day from your last 14 days, with promotions you'll feel and demotions you won't want. A COACH IN YOUR EAR Four coaches, four voices, from supportive to unhinged. Pick how hard you want to be pushed. Your goal stays on screen in your own words, right when you'd rather go back to sleep. COMMENDATIONS AND RECORDS Seventeen commendations for the mornings that count: Iron Week, No Snooze Week, Before Five and more. Every mission is timed, so there's a best to beat every morning. YOUR GOAL, AS A MAP Set the end goal, whether it's £1M, a marathon or a finished book. Milestones on the way, your position on the trail, daily orders underneath, and a warning when you've stalled. SOMEONE IN YOUR CORNER Pick one person to hold you to it. Miss an alarm and Zero Dark drafts the message; you send it. When it's hard, ask them for a push. They don't need the app. BUILT ON APPLE'S ALARMS Zero Dark uses AlarmKit, the same alarm system as the Clock app, so it rings through Silent mode and Focus. Snooze shows its price on the Lock Screen, with a live countdown. FREE Alarms, the Math, Shake and Type missions, rank, commendations, the map and your partner. ZERO DARK PRO Scan and Steps missions, the Savage and Unhinged coaches, the wake-up check, every alarm sound and unlimited alarms. £2.99 a month, or the equivalent in your currency. PRIVATE No account, no ads, no tracking. Everything stays on your iPhone. Zero Dark Pro is an auto-renewing monthly subscription. Payment is charged to your Apple Account at confirmation of purchase.
