What’s new
Version 2.0 · Updated September 18, 2026
Version 2.0 is the largest update since NFP Calendar launched: a complete redesign, a rebuilt Insights dashboard, and five Premium features. REDESIGNED THROUGHOUT Every screen has been rebuilt for iOS 26. The Chart is easier to read, the day form is quicker to fill in, and a new Today screen puts the day's entry one tap away. INSIGHTS, REBUILT A visual dashboard replaces the old summary — your Peak day pattern, cycle-by-cycle history, mucus build-up and cycle-length trends, and an overlay that aligns every cycle on its Peak day. CHARTS YOUR PRACTITIONER CAN READ Print the full Creighton chart on US Letter, choose one long page or printable sheets, and bring a follow-up prep sheet carrying the days you flagged and the questions you wrote. INTRODUCING PREMIUM! • Cycle history, trends & overlays • Home & Lock Screen widgets • Smarter charting reminders • Practitioner visit prep sheet • Apple Health sync — adds your period, spotting and mucus observations to Health, and never reads your Health data STILL FREE, AND STAYING FREE The calendar, the day form, cycle history, every PDF export, JSON and NFP Charting import, iCloud sync, and the daily reminder. ALSO FIXED Dozens of corrections, and bug squashing!
