How to actually start tracking (and what to log first)
The hardest part of tracking your cycle is not the tracking itself. It's starting. The prospect of logging something every single day — especially when you're not sure what to log or what you're looking for — can make the whole thing feel complicated before you've even begun. But here's what most guides don't tell you: you don't need to track everything. You don't need to be perfect. And you don't need to know what you're looking for before you start.
The most useful version of cycle tracking is also the simplest one. Here is exactly how to begin — what to log first, how to build the habit, and what not to worry about.
The four steps to actually starting
Log your period start date — today if it's happening, or the next time it arrives
This is the single most important data point. Day 1 of your cycle is the first day of full bleeding — not spotting. Every other data point in your cycle is measured from here. If your period isn't happening right now, open the app on the first day it does and mark it. That's your starting point.
Check in with your phase daily — takes 10 seconds
Once your period is logged, the app will show you which phase you're in. Check it each morning. Just reading the phase name — menstrual, follicular, ovulatory, luteal — and connecting it to how you feel that day is the most important habit to build. You're not logging anything yet. You're just paying attention.
Add one or two simple daily ratings
Once the habit of checking in is established, add a simple mood and energy rating each day — a 1–5 scale for each. This is enough to reveal your cycle pattern within two to three cycles. Don't start with ten categories. Start with two. Complexity comes later, after the habit is solid.
Do it at the same time each day
Habit research confirms that attaching a new behavior to an existing routine dramatically increases the chance it sticks.2 Choose a consistent trigger — when you make your morning coffee, when you brush your teeth at night, when you get into bed. The timing matters less than the consistency.
What to log — in order of priority
Essential first
Period start and end dates. Mood (1–5). Energy (1–5). These three things, logged consistently, reveal your complete cycle pattern within 2–3 months.
Add when ready
Sleep quality. Cramp intensity. Skin condition. Appetite level. Social energy. Each additional dimension adds depth to your picture without requiring much more time.
Optional extras
Specific symptoms, stress level, exercise, notable events. These add context when you want to understand why a particular cycle was different from the usual pattern.
The most common beginner mistakes — and how to avoid them
Trying to track too many things at once
Starting with twenty categories feels comprehensive but leads to overwhelm and abandonment. Start with period dates and two ratings. Expand only after the habit is established.
Giving up after missing a few days
Missing days is normal — especially at the start. Log what you remember, note that you missed some days, and continue. Imperfect data across three months is infinitely more useful than perfect data across one week.
Expecting instant insight
The first cycle gives you a baseline. The second gives you a comparison. The third gives you a pattern. Pattern recognition requires repetition — don't expect clarity after two weeks of data.
Comparing your cycle to an average
The 28-day cycle is a population average that applies to only around 13% of women. Your cycle has its own length, its own rhythm, its own symptom pattern. Track to understand yours — not to match someone else's.
What you're actually building
Every day you log is a data point. Every cycle you complete is a pattern. After two to three months, those patterns coalesce into something genuinely valuable: a personal map of your cycle — your specific energy curve, your typical premenstrual signature, your reliable peak week, your predictable low days.
That map doesn't tell you what your cycle should look like. It tells you what yours does look like. And that distinction — between the generic and the personal — is the whole point. Research confirms that women who track consistently develop a significantly richer self-knowledge of their cycle than those who track occasionally or not at all — and that this self-knowledge translates directly into better health management, less surprise, and greater sense of control over their own body.3
The only thing standing between you and that self-knowledge is starting. And starting is as simple as logging today's date, opening the app, and noting how you feel. That's it. Everything else follows from there.
The best time to start is today. Open Feelings, log your period start date, pick your mood avatar, and you're already tracking. It takes less than a minute — and your first data point is waiting.
