About

Sleep Again

Read full description

You wake up at 3am. Or 4am. Or 5am. You know you should still be asleep. But your mind is already running. Replaying yesterday, rehearsing tomorrow. You lie there, watching the ceiling, hoping sleep will come back. Sometimes it does. Often it doesn't. This is terminal insomnia. Early morning awakening. It's the most common sleep problem for entrepreneurs and founders β€” and almost no app is built for it. Sleep Again is. β€” THE PROBLEM WITH EXISTING SLEEP APPS Most sleep apps track what already happened. They show you last night's score the morning after. By then, it's too late. You can't go back and fix Tuesday at 3am. Sleep Again works differently. It analyzes your HRV, heart rate, and sleep stage data from HealthKit and calculates your risk of an early morning wake-up before you go to sleep. You see your risk each evening β€” so you can act while there's still time. β€” HOW IT WORKS Sleep Again reads your health data from Apple Health each evening. It looks at: β€’ Heart rate variability (HRV) β€” your body's real-time stress marker β€’ Resting heart rate β€” elevated HR correlates with disrupted sleep β€’ Sleep stage history β€” your recent deep sleep and REM patterns From these signals, it calculates your early wake-up risk for tonight. High cortisol days β€” heavy workouts, investor meetings, travel stress β€” show up in your HRV before you feel them at 3am. The prediction gives you a window to act: adjust your wind-down routine, skip the late workout, or simply know what's coming so you're not blindsided. β€” BUILT FOR ENTREPRENEURS Founders don't sleep poorly because of poor sleep hygiene. They sleep poorly because financial uncertainty, product stress, and the inability to mentally shut off keep cortisol elevated into the night. Sleep Again was built alongside the book "Sleep Again: Finding Rest in a World Built on Urgency" by Joakim AchrΓ©n β€” a founder who spent 15 years building VC-backed companies and sleeping terribly. The app applies the book's core insight: you can't fix a 3am wake-up at 3am. You have to act the evening before. β€” WHAT YOU GET β€’ Evening risk score β€” your wake-up risk for tonight, calculated from real health data β€’ Contributing factors β€” understand what's driving your risk (HRV drop, disruptions, overtraining) β€’ Risk trends β€” see patterns across days and weeks β€’ HealthKit integration β€” reads Apple Watch, Oura, WHOOP, and any HRV-capable device All features unlock with a 7-day free trial β€” no payment until trial ends. β€” FROM THE BOOK Readers of "Sleep Again" can unlock a 3-month pass using the QR code included in their ebook or audiobook bundle purchase. Tap "Redeem a pass" on the paywall to enter your code. β€” PRIVACY Sleep Again reads health data locally from HealthKit. Your data is not sent to external servers for processing. HRV and heart rate readings stay on your device. β€” SUBSCRIPTION Sleep Again Premium unlocks all features: β€’ $9.99/year (save 58%) β€” 7-day free trial β€’ $1.99/month β€” 7-day free trial β€’ Cancel anytime.
