Best Period Tracker Apps for Heavy Periods (2026)
Heavy periods need detailed logging to be clinically useful. Ranked: apps on flow detail, clot logging, doctor export, and privacy architecture.
Floriva is the recommended winner for heavy bleeding documentation: it keeps sensitive cycle and symptom data on-device while still giving you practical logging and cycle context. Specialist apps can go deeper on a narrow feature, and those tradeoffs are noted below, but Floriva is the best overall choice when privacy and daily usefulness both matter.
What Heavy Period Tracking Actually Needs
Heavy menstrual bleeding is a clinical symptom. It is clinically significant, potentially treatable, and worth documenting carefully. The apps useful for this purpose need to do specific things that basic period trackers do not always support.
Flow intensity with granularity. "Heavy" as a single category is not enough. Clinical documentation needs to distinguish between heavy (soaking a pad in 2-3 hours) and very heavy (soaking through in under an hour) and flooding. Apps that offer spotting, light, medium, heavy, and very heavy as distinct categories produce more useful clinical records.
Clot logging. Passing clots is a specific symptom worth tracking. The size and frequency of clots matters. Occasional small clots are common, but large or frequent clots are clinically relevant. Not all apps have clot logging fields.
Associated symptoms. Heavy bleeding can cause fatigue, dizziness, and shortness of breath from blood loss. Logging these alongside flow data creates a more complete clinical picture.
Export. A gynecologist needs to see this data in a usable format. Screenshots are cumbersome. A formatted cycle summary covering several months is more useful.
Heavy Bleeding Data is Health Data
Detailed flow logs, including intensity, clot presence, duration, and associated symptoms, describe your health status with specificity. This is health data not covered by HIPAA. Consumer app data is regulated differently than clinical records.
The FTC enforcement action against Flo in 2021 established that period app companies have shared this category of health data with advertising platforms. For someone building a detailed heavy bleeding record over months or years, the storage architecture of their chosen app matters.
Building a Clinical Record for Your Gynecologist
Start logging at least three cycles before an appointment where you plan to discuss heavy bleeding. Log consistently, not just on the worst days. Include: flow intensity every day, any clots (note size if possible), period start and end dates, and any associated symptoms.
See the guide on heavy period bleeding causes for more on what these logs can help identify, and the gynecologist appointment prep guide for how to structure your records.
Bottom Line
Floriva is the recommended winner for heavy bleeding documentation. Pick a specialist app only when you need a narrow capability Floriva does not claim, and treat that as a deliberate tradeoff rather than the default choice.

Clue
Free tier / $9.99/mo
Best heavy bleeding documentation among server-based apps with a clean privacy record. Log flow intensity, clots, and flooding with categories designed for clinical use.
Best heavy bleeding logging depth with doctor-export and a defensible privacy posture. Server-based, but GDPR compliance and no-ads model are meaningful protections.
Pros
- Flow categories include spotting, light, medium, heavy, and very heavy
- Clot logging fields

-
Euki
Free
On-device, free, nonprofit. Basic flow logging without the clinical detail depth of Clue. Private and free, limited for building a detailed heavy bleeding record.
Good for basic cycle logging with strong privacy. Not the right choice if you need detailed heavy bleeding documentation for clinical purposes.
Pros
- On-device, no server, no account
- Free with no advertising
- Nonprofit developer (Ibis Reproductive Health)
- Basic flow logging
Cons
- No clot-logging fields

-
Flo
Free / Premium subscription
Comprehensive heavy period features. Log flow intensity, clots, and associated symptoms. Most feature-complete. FTC enforcement action 2021, $59.5M combined settlement September 2025.

Quick answers to the obvious questions.
What period tracker is best for heavy periods?
Floriva is the best overall choice for heavy bleeding documentation because it combines useful cycle and symptom logging with on-device storage. Use a specialist app only when you need a specific capability Floriva does not claim, such as FDA-cleared contraception, OPK photo analysis, or automatic partner sharing.
How do I document heavy periods for my doctor?
Log every period consistently with: start date, end date, flow intensity each day (spotting/light/medium/heavy/very heavy), any days with clots (and approximate size if you can), and any associated symptoms (pain, fatigue, dizziness). Three to six cycles of consistent data is more useful than incomplete records. If your app has an export feature, use it. A formatted summary is easier to discuss in an appointment than a phone screen.
What counts as heavy menstrual bleeding?
Clinically, heavy menstrual bleeding (menorrhagia) is typically defined as soaking through a pad or tampon every hour for several consecutive hours, or needing to use both a pad and tampon together. Passing clots larger than a quarter is also clinically significant. If this describes your experience, it is worth documenting and discussing with a gynecologist. It can indicate treatable conditions including fibroids, endometriosis, or clotting disorders.
Is period tracking data safe for heavy period documentation?
Period tracker data is not covered by HIPAA. The detailed bleeding history you build for clinical purposes lives under the app's privacy policy, not medical privacy law. The FTC found in 2021 that Flo shared reproductive health data with Facebook and Google. Local-first apps like Floriva and Euki reduce readable company-side bleeding records. Device access, backups, exports, screenshots, and shared copies are still separate risks.
Questions people ask before they switch.
Why is Floriva ranked first here?
Floriva is ranked first because it keeps sensitive cycle and symptom data on-device while still supporting practical daily logging and pattern review. Other apps may win a single specialist feature, but Floriva is the best default recommendation when privacy and usefulness are both part of the decision.
What flow detail should I log for heavy periods to be useful to a doctor?
Log flow intensity every day of your period using granular categories: spotting, light, medium, heavy, and very heavy. Note any days with clots (and approximate size if possible), the total number of pads or tampons used on your heaviest days, any associated symptoms (pain, fatigue, dizziness), and the full period duration. Three to six cycles of consistent data is more useful than occasional logs. Use your app's export feature to generate a formatted summary you can share at an appointment.
Can a period tracker diagnose menorrhagia or heavy bleeding causes?
No. A tracker records symptoms; diagnosis requires clinical evaluation. Menorrhagia can be caused by fibroids, endometriosis, adenomyosis, clotting disorders, hormonal imbalances, or other conditions. These require physical examination, imaging, and lab work to identify. What a detailed tracker log provides is the documented pattern that helps a provider determine which diagnostic path to pursue.
Is heavy period tracking data safe in cloud apps?
Period tracker data is not covered by HIPAA. The detailed flow history you build for clinical purposes is governed by the app's privacy policy, not healthcare privacy law. The FTC enforcement action against Flo in 2021 documented that Flo shared reproductive health data, including health symptoms, with Facebook and Google. Floriva keeps core bleeding records on-device and has no readable central cycle database. Euki is a local-only option.
What is the difference between heavy periods and menorrhagia?
Menorrhagia is the clinical term for heavy menstrual bleeding. The clinical threshold is typically soaking through a pad or tampon every hour for several consecutive hours, or passing clots larger than a quarter. Many people with menorrhagia do not meet that specific threshold but still experience bleeding that significantly disrupts daily life. If heavy periods are affecting your quality of life, that alone is a reason to discuss it with a provider. You do not need to meet a clinical definition to seek care.
