First Light

Read full description

First Light is the alarm clock for people who sleep through everything. If you've ever set five alarms and slept through all five, you don't need another gentle chime. You need an alarm that won't quit until you're actually on your feet. First Light makes you complete a real task to turn it off โ€” so by the time the noise stops, you're already wide awake. HOW IT WORKS When the alarm goes off, you can't just swipe it away. You complete a mission: โ€ข Photo โ€” snap a specific spot in your home (the bathroom, the kitchen) to prove you're up โ€ข Steps โ€” get out of bed and walk โ€ข Math โ€” solve problems to shut it off โ€ข QR scan โ€” scan a code you've placed across the room โ€ข Shake โ€” shake your phone until you're moving โ€ข Type โ€” type out a phrase โ€ข Selfie โ€” take a selfie to confirm you're awake Pick the mission that actually works on you. Make it harder on the mornings that matter. WAKE-UP CHECK The dangerous part isn't the alarm โ€” it's the silence after. First Light checks back in minutes after you dismiss it, to make sure you didn't crawl straight back to bed. No more "I turned it off and fell asleep again." BEAT THE MORNING SCROLL Because you have to get up and move to dismiss it, you're out of bed before you ever open Instagram. Start your day on your feet โ€” not face-down in your phone. DESIGNED TO BE SIMPLE Most alarm apps are cluttered, confusing, and stuffed with ads. First Light is clean, fast, and does one thing exceptionally well: it gets you up. No clutter, no nonsense. FAIR PRICING โ€” SUBSCRIBE OR BUY ONCE Start free for a week on the yearly plan, then keep going for less than a coffee a week. Prefer flexibility? Go month to month. Prefer to pay once and own it forever? Lifetime is a one-time purchase โ€” no subscription. Pick what works for you. Download First Light and wake up on the first try โ€” for once.
