Apps (Clue, Flo, Natural Cycles) are the most convenient for prediction algorithms and reminders. Physical journals create better records for healthcare appointments. Books provide the 'why' behind what's happening hormonally — worth reading alongside a tracking tool.
Frequently asked
How accurate are cycle tracking apps?
For period prediction, well-established apps are accurate within ±2 days for regular cycles. For ovulation prediction, they're significantly less reliable — ovulation can shift by days due to stress, illness, sleep and travel.
Should I track with a physical journal or an app?
Both if possible. Apps for predictions and reminders; journal for detailed symptom notes and the record you can show a doctor. The NHS increasingly asks patients to bring cycle data to gynaecological appointments.
