Lull turns your BedJet 3 into a climate that follows you through the night. PLAN YOUR WHOLE NIGHT Build a schedule as a series of phases: warm the bed before you get in, cool it while you sleep, and warm it again before you wake. Each phase has its own mode, temperature, fan speed and length, and the whole night shows up as one simple curve. SET IT AND SLEEP Tap Start Night and the schedule is saved to your BedJet, which runs it by itself until morning. Your phone doesn't need to stay connected or even stay awake. LIVE CONTROL The Remote tab gives you cool, heat, gentle heat, turbo and dry, with temperature, fan and a shut-off timer that starts at the longest your BedJet allows. MADE FOR TWO If you and your partner both use Lull, your phones hand the BedJet to each other automatically. No more fighting over who's connected. PRIVATE BY DESIGN No account, no sign-up and no cloud. Lull talks to your BedJet over Bluetooth and keeps your schedules on your iPhone. Includes four starting schedules and a demo mode, so you can look around before your BedJet is nearby. Requires a BedJet 3. The BedJet V2 isn't supported. Lull is an independent app and is not affiliated with or endorsed by BedJet. BedJet is a trademark of its owner.
