Wake up together — even from miles apart. SyncUp is the alarm clock that actually gets heavy sleepers out of bed: sync your alarm with a wake-up buddy, solve a challenge to shut it off, or charge yourself for every snooze. Three ways to finally wake up on time. PARTNER MODE Pair your alarm with a friend, roommate, or partner and see each other's wake-up status in real time. Still snoozing? Get a nudge. It's shared accountability that works whether you're in the same house or different time zones. WAKE-UP CHALLENGES Tapping "dismiss" half-asleep isn't an option. Before your alarm stops, you'll solve a challenge — a math problem, or physically getting up to touch grass — to prove you're actually awake. Pick the challenge type and difficulty that fit your routine. PAID SNOOZE (OPTIONAL) For anyone who needs real stakes: every snooze charges you $0.99, straight from your account. Get up and you keep it. Sleep in and you pay for it. Available to everyone, free or Pro. ALSO INCLUDES - Wake-up streaks and stats to track your progress - Customizable alarm sounds, challenge types, and snooze pricing - Activity feed with your full wake-up history PLANS - SyncUp Pro — Unlimited alarms, all challenge types including partner challenges, and more. - Paid Snooze (optional) — Add extra motivation with a charge per snooze. Available to all users, free or Pro.
