Quick comparison table

Some picks stick to a simple period calendar, while others cover fertility, pregnancy, or later reproductive-health stages. Predictions are estimates based on logged data, not medical diagnoses.

1. Flo Cycle & Period Tracker

Best for: iPhone users who want the broadest set of cycle-stage tools.

Flo Cycle & Period Tracker covers periods, ovulation, fertility, pregnancy, and perimenopause in one mobile app. It supports regular and irregular cycles, and its symptom and mood logs add context to cycle predictions. Its main strength is the range of reproductive-health stages it covers, instead of stopping at period dates alone.

2. Clue: Period & Cycle Tracker

Best for: Android users who want detailed, science-focused tracking.

Clue: Period & Cycle Tracker lets you log more than 200 cycle-related factors, review predictions, set reminders, and read expert-written health content. It supports periods, ovulation, fertility, pregnancy, and perimenopause. The standout feature is its unusually broad set of tracking categories, which suits people who want to spot patterns over time.

3. Stardust Period Tracker

Best for: iPhone users who prefer a more distinctive daily tracking experience.

Stardust Period Tracker combines cycle predictions, symptom logging, daily insights, fertility forecasts, and pregnancy tracking.

Its main appeal is the mix of standard period tools with wearable and lunar-cycle options.

4. Ovia Cycle & Pregnancy Tracker

Best for: Android users who want reproductive-health support beyond monthly period tracking.

Ovia Cycle & Pregnancy Tracker includes period and fertility calendars, ovulation predictions, customizable symptom and mood tracking, and support for regular or irregular cycles. Its tools also cover pregnancy, postpartum, perimenopause, and menopause. The standout feature is its coverage of several reproductive-health stages in one app.

5. Period Tracker

Best for: Android users who want a straightforward calendar-based option.

Period Tracker records period dates and estimates future periods from previous cycle data. You can also track ovulation, fertile days, moods, symptoms, notes, and intimacy. Its main strength is a simple period-calendar experience with optional logs for people who want more detail.

6. Period Tracker - My Calendar

Best for: Android users who want adjustable settings and account flexibility.

Period Tracker - My Calendar predicts periods and fertile days using customizable cycle settings, and it supports irregular-period tracking. Health check-ins give you another way to record how you feel. Backup, restoration, and multiple accounts also make it easier to manage more than one tracking profile. That account flexibility is its clearest standout feature.

7. Glow Ovulation & Period App

Best for: iPhone users focused on ovulation and fertility signs.

Glow Ovulation & Period App tracks periods, cycle length, flow, symptoms, ovulation, and other fertility indicators. Personalized insights can help you review patterns, while Apple Health integration connects cycle information with other health data. Its standout feature is the way it combines period and fertility tracking with an existing Apple Health setup.

8. MyFlo® Period Tracker Calendar

Best for: Android users who want guidance tied to hormonal-health stages.

MyFlo® Period Tracker Calendar records period dates, cycle length, flow intensity, PMS symptoms, ovulation, and fertile-window information. Instead of focusing only on calendar dates, it organizes guidance around cycle-syncing and broader hormonal health. Its standout feature is this stage-based approach to interpreting everyday tracking information.

How we picked these apps

We compared how each period tracker handles period dates, cycle predictions, symptoms, moods, ovulation, fertile windows, and broader fertility tracking. More detailed logs can help you spot patterns, while basic calendars may be faster for recording start and end dates.

We also checked support for irregular cycles and whether each app covers pregnancy, postpartum, perimenopause, or menopause. Platform availability matters too, so iPhone and Android users can quickly rule out apps they cannot use.

Finally, we separated simple calendar tools from apps with deeper logs, health integrations, reminders, expert content, or broader reproductive-health features. The result is a mix of lightweight trackers and more comprehensive options.

Frequently asked questions

How do period tracker predictions work?

Most predictions use previously logged cycle dates, cycle length, and sometimes symptoms or ovulation information. As you add more accurate data, the app may adjust its estimates, so predicted dates can change over time.

Are predictions reliable with irregular cycles?

Irregular cycles can make estimated period, ovulation, and fertile-window dates less reliable. An app may still help you record patterns, but its forecast should not be treated as a precise schedule.

What is the difference between a basic calendar and a fertility tracker?

A basic period calendar mainly records bleeding dates and estimates future periods. A fertility-focused tracker may also record ovulation signs, symptoms, cervical changes, moods, and other cycle factors to give you a broader view.

Tracking apps are not substitutes for professional medical advice, pregnancy testing, contraception guidance, or evaluation of unusual symptoms. Speak with a qualified healthcare professional when you need medical help.

The verdict

Flo Cycle & Period Tracker is the strongest overall pick for its coverage of periods, fertility, pregnancy, perimenopause, symptom logging, and cycle predictions. Its iOS availability is a limitation for Android users. On Android, Clue is the runner-up for detailed tracking and science-focused content. Ovia is another strong choice if you want tools covering fertility, pregnancy, postpartum, and menopause.
