Top-of-the-line period-tracking apps on the market, Clue, not too long ago introduced a function that ought to be groundbreaking for individuals who do not menstruate however nonetheless expertise cyclical well being adjustments. The app claims to be the one well being app that tracks your cycle even once you don’t bleed. This may imply individuals who haven’t got intervals on account of surgical procedure, hormonal medicines, gender transition, or life phases like post-menopause can monitor their cycles, too.
The premise is strong and much-needed. Even once you don’t expertise bleeding, your cyclical adjustments in temper, vitality, and bodily signs do not simply disappear. These patterns matter for understanding your physique, managing well being situations, and making knowledgeable selections about your well-being. Clue deserves credit score for recognizing this hole in reproductive well being monitoring.
However here is the place the thrill deflates, and the place there is a basic flaw all through the interval monitoring trade: These apps are nonetheless glorified diaries. If you can begin a brand new “cycle” everytime you really feel prefer it, then your monitoring is predicated on vibes, primarily. This is the difficulty with customers manually figuring out their very own patterns, even when the expertise to detect cycles mechanically already exists.
How interval monitoring at the moment works (and the way it does not)
Conventional interval monitoring apps function on a easy premise: you inform the app when your interval begins, and it makes use of that information to foretell future cycles and fertile home windows. This works moderately nicely for folks with common menstrual bleeding, but it surely fully excludes anybody who does not bleed—an enormous inhabitants together with folks utilizing hormonal contraception, those that’ve had hysterectomies, folks on gender-affirming hormone remedy, and post-menopausal people.
Clue’s new function makes an attempt to unravel this by letting customers manually begin a brand new “cycle” each time they need, based mostly on how they’re feeling. However this is not essentially totally different from current interval apps—it is simply changing “I am bleeding” with “I believe I am beginning a brand new cycle.” Customers are nonetheless required to self-diagnose their cyclical patterns somewhat than having expertise detect them.
The issue is that if you do not have common intervals, you usually do not know when your cycles start or finish. That is exactly why you’d need monitoring within the first place.
The expertise is on the market
What makes this significantly irritating is that the expertise to detect cyclical patterns with out handbook enter not solely exists—it is already constructed into the gadgets thousands and thousands of individuals put on each day.
Beth Skwarecki, who has been testing wearables that provide ladies’s well being options, captures this completely: “I do not get common intervals however I do not know whether or not I’ve a cycle—some folks on my type of contraception do and a few do not. So I get excited each time I hear {that a} machine can use physique temperature to foretell ovulation, or {that a} machine appears to be like for patterns in your physique’s metrics. However I have never discovered a single one which even makes an attempt to do cycle monitoring with out you manually flagging days that you’re bleeding.”
The science is straightforward: Physique temperature usually rises about half a level throughout the second half of your cycle in comparison with the primary half. The day your temperature rises coincides with ovulation, and the day it drops aligns with once you’d usually have a interval.
Oura, Whoop, most Garmin watches, Apple Watch, and just about each premium smartwatch already monitor physique temperature for these actual variations. And plenty of of those wearables will determine the dates they assume you’re ovulating—however provided that, and after, you manually flag the dates you observed bleeding. As Beth factors out, this looks as if an awfully restricted use of this information given the trouble these platforms put into analyzing and detecting patterns in all of the different information they acquire. Whoop will tell you whether you sleep better on nights you’re better hydrated. Oura will inform you when your physique temperature and different metrics seem to suggest you’re getting sick. But by some means, none of them apply this information to detect cyclical patterns independently.
“With the entire effort Oura (and Whoop, and different wearables) put into detecting patterns in your private biometrics,” Beth explains, “it looks as if an enormous omission that they do not level their algorithms on the query of ‘Does this person have a cyclical month-to-month sample of their temperature information?‘”
What do you assume thus far?
Apart from, temperature is just the start. Trendy wearables monitor coronary heart fee variability, sleep patterns, exercise ranges, and stress indicators—all metrics that can fluctuate cyclically in folks with hormonal cycles, no matter whether or not they menstruate.
Who this actually impacts
As somebody squarely in Clue’s goal demographic for this function, I do not need to guess when my cycle begins—I would like the app to inform me based mostly on the signs I am logging. If I knew when my cycles started and ended, I would not want specialised monitoring within the first place. The entire worth proposition of cycle monitoring apps is sample recognition that people may miss.
Give it some thought: in the event you can arbitrarily declare a brand new cycle based mostly on how you feel, what’s stopping you from simply logging “bleeding” in an everyday interval app and getting the identical performance? What’s desperately wanted—and what continues to elude each main well being app—is clever sample detection. An app that may analyze your logged signs (temper swings, vitality dips, complications, sleep adjustments, no matter your physique does) and say, “Hey, based mostly in your information from the previous few months, it appears to be like such as you is likely to be beginning a brand new cycle round now.”
Individuals who do not menstruate however nonetheless expertise hormonal cycles usually battle with signs that docs dismiss or do not absolutely perceive. Having data-backed proof of cyclical patterns may validate their experiences and inform higher healthcare selections.
I do assume Clue is midway there by encouraging customers to log temper, vitality, and well being experiences to “join the dots” and “observe patterns.” The power to trace well being patterns “in your phrases” with out the stress of menstrual bleeding is effective. But it surely’s nonetheless asking customers to do the connecting and observing themselves. If my Oura or Whoop or Apple Watch is monitoring all these metrics in any case, why is not it discovering patterns associated to my cycle?
And albeit, if I need to analyze my very own symptom patterns, I will simply use an everyday note-taking app and save myself the privacy concerns.
