Earlier this month , popular period - cross app Clueannouncedit had receive FDA clearance for a digital birth ascendence feature in its app . Now , per a Vergereport , Natural Cycles , the other FDA - cleared birth restraint app , is pissed because of how the FDA granted that headroom , sparkingsome kick between the two apps . Meanwhile , I ’m sitting here wondering why we ’re even discourse companies squabbling over regulatory semantics when we should be call into question why birth control apps are a affair in the first topographic point .
There ’s no deficiency of fertility apps out there . Some add up with thermometer so you could measure your basal soundbox temperature . There ’s even awearablethat dog metrics like core rate , perfusion , and dead body temperature to predict a fair sex ’s fertile window . similarly , Natural Cycles and Clue ’s forthcoming birth ascendance feature are both iterations of Fertility Awareness Methods ( FAM ) . FAM generally expect you to either graph your menstrual cycle , check your cervical mucus , or log your basal organic structure temperature every morning before get out of bed . It ’s most precise if you do a compounding of all three . If done perfectly , FAM can be in force at preventing pregnancy . The reality is that with typical use , FAM has a unsuccessful person charge per unit of about 25 % , accord to both theCDCandPlanned Parenthood .

Part of the reason why there ’s such a mellow failure pace for FAM is human erroneous belief . People have a concentrated prison term being consistent every day , 100 % of the time . This was reliable before apps , when women marked their hertz on a forcible calendar or an Excel canvass . menstruum - trailing and fertility apps simplify the logging process and make your data much more approachable . And if you add a prognostic algorithmic program to the mixture — especially one like Natural Cycles ’ , which has FDA headway and some clinical studies to back it up — it confers an aviation of accuracy and reliability , whether it ’s guarantee or not .
That ’s fine if you ’re a couple try on to have a sister . If you ’re a cleaning woman who is n’t trying to get meaning and perfectly does not want a sister , FAM - base birth controller apps are a tragedy waiting to take place . If the app fails — as Natural Cycles did for at least37 women women in 2018 — the monetary value is high-pitched .
But sure , if the FDA yield the OK , that means it ’s accurate , right ? When the FDA give Natural Cycles de novo clearance , it read in itspress releasethat the app ’s typical failure charge per unit was 6.5 % , or about 93 % efficacy . cue arrogate to be 92 % effective at preventing undesirable gestation . Those seem like pretty in high spirits numbers and a pronounced decrease from the 25 % loser rate of traditional FAMs . But those number do n’t tell the whole story .
The problem is there ’s still a shipload of thing we do n’t get laid about woman ’s wellness . Clinically verbalise , there ’s alack of foundational data , because in the past , trial subjects were almost always manlike and women were oft chuck out from written report because of their periods . ( Fun fact : Congress did not involve women to be include in clinical trialsuntil 1993 . ) To this Clarence Shepard Day Jr. , womenreceive poorer medical caredue to medicine ’s manlike bias . While Clue and Natural Cycles have conducted their own studies , they ’re mere driblet in a very empty bucket . Their study also focus on consummate use scenarios , which few women attain . We do n’t know crucial datum like how well app - free-base birth ascendance works for women with conditions like PCOS or adenomyosis . We also do n’t get laid how many women were too embarrassed to report undesirable gestation after using the app , and how that might bear upon its failure charge per unit .
Both Natural Cycles and Clue basically got their headway because the FDA deemed them to be a low to medium risk for trauma . Try enjoin that to the women who used the app and still became pregnant . A Guardianarticledetailed the experiences of woman who feel unwanted maternity from using the app . Two ended up have abortions , with one saying the experience was traumatic , led to a partitioning of her relationship , and thrust her into “ a stone pit of despair . ” Another kept the sister but noted the experience had hold away her good sense of control . None of those experiences particularly feels like a “ low to medium ” risk , especially when you moot thepotential menace of violenceagainst women with undesirable pregnancies .
In the case of the 37 Swedish cleaning lady , Natural Cycles was reported to the Swedish Medical Products Agency . After an investigation , they found that thefailure rate was in contrast with expectations , but that the company should be clearer about the risk of unwanted gestation . However , the danger of birth control apps is n’t necessarily in their loser rate . We ’ve all learn in school that all methods of parentage control can fail . It ’s in the fact that it subtly encourages charwoman to skip the doctor ’s office .
To be fair , Clue ’s intersection has n’t launched yet so we ca n’t say for certain what it ’ll be like . We can , however , look at how Natural Cycles has market itself . If you go to the Natural Cycles website , it shoot a line its FDA headway and the fact that it ’s prescription - devoid all over its homepage . It encourages me to “ take control condition of my birthrate ” and severalise me that it has no unwanted side personal effects . It also says that if you leave to measure your temperature , the app does n’t become less effective . That sounds too good to be true , though there is a disclaimer at the bottom of the internet site that acknowledge the app can not guarantee a substance abuser will not get pregnant .
Out of oddity , I require the Natural Cycles quiz about whether this contraceptive was “ proper ” for me . It should n’t be , as I have polycystic ovary syndrome ( PCOS ) and am terrible at taking my medication every day , let alone my temperature before I get out of layer . rather , my quiz results gently require if I could consider changing my bit . It said that my current method acting of birthing control — the NuvaRing — was internal secretion - based and asked if I had noticed any side force . It proceeded to say Natural Cycles was hormone - free and just as effectual as the ring . My termination also aver my PCOS , which have in mind I have highly temporary and infrequent cycles , would n’t impact the app ’s efficaciousness — just that I might be told to not have sexuality on more frequently until the algorithm “ receive to know me . ” This is subtly manipulative , and of course , project to win over me to give Natural Cycles a try . If the quiz were designed with my wellness in mind , it should ’ve told me that I was n’t a gravid candidate , detailed the reasons why , and encouraged me to consult a doctor before pull in any decision .
Instead , my quiz issue contradicted every conversation I ’ve ever had with my gynaecologist and medico . Because I have PCOS , my doctor apprise that I should be on a hormonal contraceptive if I need regular periods , and then took the time to figure out which method acting would work substantially for me . She answered all my question and walked me through the pro and hustle of each . In an ideal existence , every char seeking parturition ascendency would have this conversation with a medical professional person to make an train choice about what was best for her health — not a ship’s company ’s bottom phone line . These are perfectly not conversation that should be skip because it ’s more commodious to download an app . What ’s worse is that you ’re most likely to seeads for Natural Cycles from influencers and on social medium sitesfrequented by young user — users who may be more tempted to parry their age in society to get entree to “ birth restraint ” without parental cognition .
There ’s nothing wrong with Natural Cycles or Clue using FAM to help couples who want to be pregnant . There would n’t be any contestation if they market their product as fertility app . But considering the risk that unwanted maternity pose , the FDA should re - examine what it believe “ low risk . ” In the meantime , prescription - free birthing control apps should n’t be a thing .
Correction , 2025-05-15 , 5:50 pm : This clause has been updated to elucidate that while Natural Cycles had been reported to Swedish officials after 37 char have undesirable pregnancies , they have not been action . We regret the error .
After initial publishing , Natural Cycles CEO and Co - founder Elina Berglund sent the next instruction :
“ There are often a lot of misconception around Natural Cycles and digital birth control in general , which we have aimed to pull in up over the past four years . Unfortunately , when we take an article like this , it ’s vindicated we still have a ways to go and our concern farm as other forms of digital parturition restraint lead off to enrol the market place , which could add even more confusion . Natural Cycles is gallant to extend fair sex a non - hormonal option that is backed by not only four published clinical work that limn our 93 % typical use effectiveness , but more than four old age of real - world grounds that includes follow ups with 98 % of users . ”
Correction , 2025-03-24 , 12:05pm : A late interlingual rendition of this clause connote there was no disclaimer on Natural Cycle ’s homepage . The textual matter has been update . We regret the mistake .
