What's New in Niah

Fixes and polish: • Screens now fit your iPhone properly: no extra space above titles, and the tab bar sits at the bottom edge. • On iPhone, Settings › Your data › "Doctor summary (PDF)" creates a PDF you can share. (The 1.6.1 notes wrongly said it shares an HTML file.) • Today: the note about the symptoms you logged reads more clearly, and if your data can't load, Today says so and lets you try again. • Temperature, weight and bump measurements keep their decimals, typed with a comma or a point, in every language. • If a save fails during setup or in pregnancy or postpartum mode, what you entered stays on screen until it saves. • Confirmation messages show in full, and VoiceOver reads what will happen. VoiceOver also reads chart values and Insights pattern bars. Everything still works offline, with no account.
