Bearable, Daylio, Clue or Tideline for
premenstrual mood

4 min read · checked against its sources · updated 17 Oct 2026

For premenstrual mood, no single app wins everywhere. Bearable gives you the most control, Daylio is the quickest for a plain mood log, and Clue is the broadest cycle app. Tideline is the one built around a single sentence a day and a report that sets the week before your period beside the week after it starts. Which fits depends on how much effort you'll put in each day and what you want to show someone at the end.

This comparison uses each app's own App Store listing or website, read in October 2026. I haven't used all four side by side, so it covers what the pages state, not how each one feels after a month.

Which one takes the least effort

Daylio's listing says you can make your first entry in two steps. That is hard to beat for a plain mood log, and it works well if tapping an icon is all you can manage on a bad day.

Tideline asks for one sentence, typed or spoken, and sorts the mood and symptoms into the right cycle day for you. You can also tap through a list. Speech-to-text runs on the device. If you'd rather talk than tap, see how to log your mood by voice.

Bearable asks the most up front. You choose what to track, which is the point, but it takes setup. Its page doesn't mention voice logging.

Which one knows where you are in your cycle

Clue and Tideline are cycle apps first. Clue logs mood, energy, cravings and sleep, helps you anticipate PMS and cramps, and has modes for trying to conceive, pregnancy and perimenopause. Tideline files each entry under its cycle day and counts down to the next period and to harder days.

Bearable lists menstrual cycle tracking among its features. Daylio's listing doesn't mention periods or cycles, so a mood log there has no cycle day attached unless you add it yourself.

What you can hand a doctor

This is where Tideline is different. After two cycles it builds a report that compares the week before each period with the week after, symptom by symptom, and quotes your own words. It can be saved as a PDF. The report is part of the paid Tideline Plus subscription, and logging, history and export are free. Why that comparison matters is covered in showing your doctor that symptoms follow your cycle and why doctors ask for two cycles.

The others give you data to share rather than that comparison. Bearable advertises 30+ reports and export. Daylio exports PDF and CSV. Clue's listing names charts of your patterns but no report or export.

Privacy

Tideline keeps entries on the phone, with no account and no server. Daylio says data is stored locally with optional backups. Bearable says health data is encrypted before it is backed up to its servers. Clue's privacy label lists health data as linked to you, plus an identifier used for tracking. These are the developers' own declarations on their pages, not checked by Apple. More on this in private period tracker, no account.

Where the others are better

Bearable is better if you want to define your own symptoms and see correlations. Daylio has far more ratings, runs in 47 languages and lists accessibility features. Clue is the stronger pick for fertility prediction, wearable connections and its library of 400+ articles. Tideline has no public ratings yet, and its listing doesn't diagnose, treat or prevent anything.

Which to pick

If a PMDD diagnosis is the goal, ask your clinician which format they accept. For a wider checklist, see PMDD tracker app: what to look for.

Keep the record your doctor needs. Tideline is a period and mood tracker for iPhone: write one sentence a day, and after two cycles it puts the week before your period next to the week after it starts. Free to track, no account.
