Comparing period, cycle and menopause trackers
Most people arrive here because an app they already use stopped fitting — the price went up, the privacy policy changed, or their cycles changed and the app did not. This page is the checklist we would use, followed by our own side-by-side comparisons.
When comparing tracking apps, check six things: which life stages it covers, what you can actually record, whether it produces a summary you can take to an appointment, whether it runs on your devices including a browser, the real price after any trial, and how the company makes money. HarmoFlux covers first periods through postmenopause, records symptoms, moods, medications and supplements, produces a doctor-ready PDF, runs in a browser and on iPhone, costs $0, $1.99 or $4.99 per month, and is funded by subscriptions rather than advertising.

1. Which life stages does it cover?
Most tracking apps were designed for the cycling and fertility years. That is fine until your cycles change. Ask whether the app still makes sense for you in perimenopause, after your final period, and in the years after that — and what happens to your history if you have to move.
- Does it handle irregular and skipped cycles without treating them as errors?
- Does it have anything to say once periods stop?
- Can you export your history if you leave?
2. What can you actually record?
Cycle apps are usually strong on bleeding and cycle-related symptoms. Fewer of them treat medications and supplements as first-class entries, which matters if you are taking anything regularly and want the timing written down next to how you felt.
- Symptoms, severity and free-text notes
- Mood, sleep and energy
- Medications and supplements with dose and timing
- A note for how you felt after taking something — recorded as timing, never as proof of cause
3. Can you get a summary out of it?
Appointments are short. An app that can assemble your own entries into a dated summary is doing something a notebook cannot. Check whether the export is a readable document or just a raw data dump, and whether it costs extra.
4. Where does it run?
Browser access matters more than it sounds. It means you can use the app on a work laptop, an Android phone and a tablet without installing anything, and you are not locked to one app store.
5. What does it really cost?
Compare the price after any introductory offer, in your own currency, and check what the free tier includes rather than what it advertises. HarmoFlux publishes a free plan, Core at $1.99 per month and Plus at $4.99 per month.
6. How does the company make money?
This is the question that explains the privacy policy. An app funded by advertising has a reason to know things about you; an app funded by subscriptions does not. Read the policy for four specifics rather than trusting a slogan:
- A named list of the third parties that process your data
- A stated retention period, not 'as long as necessary'
- A self-serve way to delete your account and your data
- A direct statement about whether health data is used for advertising
HarmoFlux is funded by subscriptions. It shows no ads and does not sell personal health data, and its subprocessors, retention periods and deletion process are published on the privacy pages linked below.
Our side-by-side comparisons
- HarmoFlux vs Flo — lifecycle coverage, medication tracking and pricing against the most widely used cycle app.
- HarmoFlux vs Clue — lifecycle coverage and browser access against a long-established cycle tracker.
- Period trackers that don't sell data — how to verify funding and data-sale claims for any app.

Each comparison carries a facts-checked date and describes the other app only from its own publicly available information. Names mentioned are trademarks of their respective owners and are not affiliated with HarmoFlux.
What none of these apps do
- None of them is a medical device, and none diagnoses conditions.
- None can establish that a medication or supplement caused a symptom.
- None replaces a physician or pharmacist, and none is an emergency service.
Common questions
What should I compare when choosing a period or menopause tracking app?
Compare six things: which life stages the app covers, what it actually lets you record, whether it produces a summary you can take to an appointment, whether it works on the devices you own including a browser, the real price after any introductory period, and how the company makes money. The last one explains most of the differences in the others.
Is there a private alternative to Flo?
Several apps position themselves on privacy, and the honest way to judge them is to read the privacy policy rather than the marketing. Look for a named list of third parties that process your data, a stated retention period, a self-serve way to delete your account, and a clear statement about advertising. HarmoFlux publishes all four.
Do I need a different app for perimenopause?
Many people end up switching because apps built around fertility and the reproductive years stop fitting once cycles become irregular. That switch usually means leaving your history behind. An app that covers the whole lifecycle avoids the switch, though it is not the only way to solve the problem — exporting and keeping your own records also works.
Does HarmoFlux claim to be better than other trackers?
No. HarmoFlux covers a wider span of life stages, tracks medications and supplements alongside symptoms, and produces a doctor-ready PDF summary. Whether that combination matters more to you than a refined cycle-only interface is your call, and no app here is a medical device.
