About
Your sleep is a running balance. Good nights deposit, short nights withdraw. Pennie, a warm copper piggy bank, shows where you stand and walks you through a quiet weekly ritual to catch back up.
No hustle. No optimization. No shame. Just a quiet weekly ritual and a number that tells you where you stand.
FROM A NIGHT'S SLEEP TO A SUNDAY HABIT
• PASSIVE TRACKING
Pennie reads sleep from Apple Health. You sleep, we count. No extra hardware, no fiddly logging.
• A RUNNING 14-NIGHT BALANCE
A signature 270° gauge shows your balance: hours owed, hours banked. Updated every morning.
• THE SUNDAY RITUAL
Three quiet minutes every Sunday. A statement of the week, one line from Pennie, and a repayment plan you actually want to follow.
• REPAYMENT PLAN, ON YOUR PACE
Pick Gentle (+30 min/night), Steady (+1 hour), or Ambitious (+1.5 hours). Bedtime events sync to Apple Calendar in one tap.
• FORECAST WITHOUT THE FEAR
See the next 30 nights at your current pace, plus a typical-dip heatmap of where your energy historically wobbles. Patterns, never predictions.
• APPLE WATCH + WIDGETS
Six widget families: small, medium, large, lock-screen circle, rectangle, inline. A wrist app and complications that keep your balance one flick away.
• WEEKLY SHARE CARD
Tap the gauge on Sunday to export a five-second vertical clip of your week. Strava-grade restraint. Share Pennie without sharing numbers you'd rather keep.
WHAT WE'RE NOT
Not a medical device. Nightpenny does not diagnose, treat, or prevent any condition.
Not a pressure cooker. No streaks to break. No red alerts. Debt is a number, not a character flaw.
Not a data broker. Sleep stays on your phone. No server, no ads, no data sold. Analytics is opt-in and never carries numeric sleep values.
THE SCIENCE, QUIETLY
Balance is computed using a 14-night rolling sum (Van Dongen et al. 2003), with surplus above 1h discounted at 40% (recovery is slower than accumulation, per the Sleep Foundation), and clamped at −8 hours. Full methodology lives inside the app, in Settings → About.

Nightpenny now works with Siri. • Ask your balance: say "What's my sleep balance in Nightpenny" and Pennie answers out loud, no tapping needed. • Tonight's target: ask how long to sleep tonight, and Pennie reads your goal back. • Log by voice: tell Siri to log last night and land straight on the entry screen. Plus small refinements and bug fixes throughout. Sleep well.
