1.1
May 3, 2026
v1.1 — what changed • Refreshed visual design — Phosphor icons throughout, tighter palette, calmer screens. • Passive fertile-window indicator on the calendar (opt-in, off by default). Estimated only — not a contraceptive, not for family planning. • Cycle Summary Card refresh — the "next period in N days" countdown is now the hero, not buried. • Trial visibility — see exactly where you are in your 7-day trial from Settings. • Faster, clearer day-detail logging. • Various fixes and polish. Pricing unchanged. $1.99 once, never a subscription. Ever.
