About Nightpenny
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. PRICING Free • Current balance + last 7 nights • Pennie's daily greeting Premium • Full 14-night ledger • The Sunday Ritual + Calendar sync • Repayment Plan + 30-night Forecast • All six widgets, share card, Apple Watch app • Rich notifications and the full Pennie speech library $6.99 / month (billed today, no trial) $59.99 / year (14-day free trial, save 30%) Built by Foxtaming, an indie studio of one.

What’s new
Version 1.2 · Updated June 23, 2026
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.
