Natural Cycles Discount Code

Natural Cycles is the first and only app cleared by the FDA as a form of birth control — a distinction that sets it apart from the many period trackers available on the market. Used by over 6 million people across 35+ countries and backed by 27 peer-reviewed studies, it offers a hormone-free way to understand fertility, avoid or plan pregnancy, and track cycle health across different life stages. If you are looking for a Natural Cycles discount code, BudgetFitter lists verified deals including 20% off your subscription plus a free NC° Band.

How Natural Cycles Works

Green Days and Red Days

Each day, the app assigns a Green Day or a Red Day based on your cycle data. Green Days indicate low fertility — no additional contraception is needed. Red Days indicate that you could be fertile, so extra protection is required. The algorithm builds this picture from your daily basal body temperature readings, learning your individual cycle rather than assuming a standard 28-day pattern. Over time, predictions become more personalised as the app accumulates more of your data. The result is a fertility picture that reflects your biology rather than a statistical average.

Effectiveness is 93% with typical use and 98% with perfect use — meaning never having unprotected sex on a Red Day. These figures come from 27 peer-reviewed studies, and the app carries FDA clearance plus certification in over 35 countries. For context, typical-use effectiveness is comparable to the contraceptive pill, but without the hormonal side effects that lead many people to seek an alternative in the first place.

Modes for Every Life Stage

Natural Cycles covers more than contraception. The app has five distinct modes: NC° Birth Control, NC° Plan Pregnancy, NC° Follow Pregnancy, NC° Postpartum, and NC° Perimenopause. This makes it a long-term tool rather than a single-purpose app — you can switch modes as your needs change without needing a new subscription or starting from scratch. The underlying data you have already collected carries forward, giving the algorithm a richer picture of your cycle history as your circumstances evolve.

The app integrates with Apple Health and Google Fit, allowing you to cross-reference cycle data with sleep, activity, and other health metrics. It is available on iOS and Android, and is designed with data privacy as a core principle — your intimate health data is not sold to advertisers or third parties. For those building out a broader health routine, Together Health offers a range of supplements suited to supporting general wellbeing alongside cycle tracking.

The NC° Band

The NC° Band is a wearable sensor worn on the upper arm during sleep. It takes continuous temperature readings overnight and syncs the data to the app automatically, removing the need to remember a morning oral thermometer reading. This is particularly useful for people with variable schedules or those who find the daily measurement routine difficult to maintain consistently. The free band included with BudgetFitter deals removes the upfront cost of the wearable entirely, making the switch to hormone-free tracking more accessible from day one.

Getting a Natural Cycles Promo Code

Natural Cycles is available on annual or monthly subscription plans. The annual plan offers a lower per-month cost, while the monthly plan suits those who want flexibility before committing long-term. Both plans give full access to the app’s features and the ability to switch between modes. BudgetFitter’s verified Natural Cycles discount code gives 20% off the subscription price along with a free NC° Band — check the Natural Cycles deals page on BudgetFitter for the current offer.

Pair your cycle tracking with supplements from Higher Nature for hormone balance support, or explore skincare that adapts to your cycle with helloSKIN. Both brands are listed on BudgetFitter with active deals.
