7. NATURAL CYCLES APP
What: An app that tracks your menstrual cycle and other variables to work out when you’re fertile and when you can (theoretically) have protection-free intercourse without fear of pregnancy.
Effectiveness: The app’s creators claim it’s as effective as the pill.
Need to know: Natural Cycles is recognised by the government of the UK as an approved method of contraception, but many remain unconvinced. ‘Fertility apps use algorithms, the majority of which are proprietary and have not been methodologically evaluated in peer-reviewed literature,’ says Dr Cardoso.
Cost: Free on App Store and Google Play.
