The pitch

Nightpenny is a HealthKit-native sleep debt tracker for iPhone and Apple Watch. It visualises the user's last 14 nights as a savings account — short nights are withdrawals, good nights are deposits — and walks them through a quiet Sunday ritual to plan the week ahead. Built on the Borbély two-process model and Van Dongen's 2003 chronic restriction study. On-device only. Free to install.

Typography

Display: Fraunces, a contemporary serif with optical sizing. Used for headlines, tagline, and Pennie's spoken voice. Variable font (weight / opsz / soft / wonk).

Body: System UI sans, falling back to Helvetica Neue and the platform default. Aim is neutrality so Fraunces does the personality work.

How to spell & pronounce

• Nightpenny — one word, lowercase elsewhere except start of sentence. The hyphenated “Night-Penny” or two-word “Night Penny” are incorrect.
• Pennie — the mascot. Spelled with an -ie, not -y. (Distinct from the brand name.)
• Foxtaming — the publishing studio. One word.
