Caffeine & sleepPerkly
Enjoy the perk. Protect the sleep.
See how caffeine is likely to decay through your day and find a last-call time that works with bedtime.
Night LabFind what helps you wake up rested.
Rate your morning, connect Apple Health and test one sleep habit at a time to learn what helps you wake up rested.
Start with how you feel
A longer night or a higher wearable score does not automatically mean a more rested morning.
Keep the core free
Morning tracking, experiments and simple charts are free. Night Lab+ adds deeper insights and optional AI-written reports.
Health data, handled carefully
Raw HealthKit samples stay on your device. Check-ins and derived nightly summaries can sync to Bornly. Health data is never sold or used for advertising.
What it does
Deep enough to help. Focused enough to learn fast.
Night Lab pairs how rested you feel with your recorded nights. Start with seven baseline mornings, then try one habit for 14 nights and compare your mornings. An honest result can be better, worse or no clear difference. The app is awaiting its first App Store release.
A morning check-in
Rate how rested you feel from 1 to 10, with optional context about your night. Your answer stays separate from wearable estimates.
Apple Health and manual nights
Use recorded sleep from Apple Watch or another compatible Apple Health source. Without a wearable, add bed and wake times yourself.
One habit at a time
Collect seven baseline mornings, then follow one 14-night experiment. Start with sleep opportunity, wake-time consistency, caffeine cutoff or morning light.
An honest comparison
Compare followed mornings with your baseline, including the number of nights and uncertainty. No clear difference is a useful result too.

Questions
Before you install.
Can I download Night Lab yet?
Night Lab is awaiting its first App Store release. You can read the sleep guides now or email Bornly to ask for launch updates. A launch-update click opens your email app; it does not subscribe you automatically.
Do I need an Apple Watch?
No. Night Lab supports compatible sleep records in Apple Health and manual bed and wake times. Wearable stages are optional, and a rested check-in does not require a watch.
How long does a sleep experiment take?
The planned first journey is seven baseline mornings followed by a 14-night experiment. Missed or unfollowed nights can extend the calendar window. The app does not promise an improvement or a conclusive result.
Is Night Lab's sleep score Apple's Sleep Score?
No. Night Lab uses its own calculation: half how rested you report feeling and half recorded sleep context. Apple has a separate Sleep Score. The numbers have different inputs and should not be compared as equivalent measures.
Does Night Lab diagnose or treat sleep problems?
No. Night Lab provides educational sleep coaching and personal observations. It does not diagnose insomnia, sleep apnea or other conditions, and a personal experiment cannot establish medical causation.
Educational sleep coaching, not medical advice. Speak with a healthcare professional about persistent sleep problems, breathing pauses or excessive daytime sleepiness. Do not delay care to finish an experiment.
