Try our cycle tracking app: analyze and predict menstruation, ovulation, and fertile days. We're not going to suggest that you evaluate mood shifts, drink water, or analyze your steps or hours slept, but you can enter any information about every day if you want to. The app is cloud-based: you don't need to worry about backups or iCloud space. If the need arises, RedCalendar will also work in airplane mode, so you can add your data and sync it later when you're back online. ANALYSIS AND PREDICT We use the median values of data you input to calculate your cycle. That's better using the average and more honest than talking about artificial intelligence. The app will adapt to you. And if you're prescribed pills to regulate an irregular cycle, enter what your new ideal cycle looks like in the settings and the app will remember them for 3 months. REMINDERS We send notifications at 9:00 and only about what matters: 2 days before your cycle starts, a day after the end of menstruation (if you forgot to mark it), and 4 days before your predicted ovulation. If you go on vacation, and your time zone changes, open the app, so we know. TAGS Use tags for giving additional info about the day. Just add one or more custom tags and track your workouts, emotions or new habits. Use the app every day as your personal dairy. PAYMENT AND SUBSCRIPTIONS The app is free to use and ad-free
