Luteal helps you understand what is happening, feel understood, and find support through cycle-related shifts that can be hard to recognise from the inside — especially when timing is irregular, emotions feel louder than usual, or words are hard to find.
Everything is designed to feel safe, calm and under your control: your data is encrypted, adding a partner is always optional, and any guidance starts with your experience first. Partner thoughts only join that picture when you explicitly invite them in.
Free forever. No ads, no payments, no selling sensitive data.
It is built to help you understand yourself more clearly, feel understood by the people around you, and find steadier next steps when the month suddenly stops feeling manageable.
Notice mood, body changes, relationship shifts and day-to-day functioning in seconds, or leave a fuller diary entry when you have more to say.
See recurring windows, irregular-cycle patterns and familiar spirals more clearly, even when it is hard to recognise them from the inside.
Tell your partner what you need without having to explain everything perfectly in the moment, and without giving up control of your private space.
Pause the urge to act permanently on a temporary state, return to what helps, and find guidance that feels practical, calm and non-judgemental.
Luteal is not here to tell you your feelings are not real. It is here to help with context, timing and next steps — to separate what feels true, what may be louder than usual, and whether something needs action now, later, or with support.
See the day more clearly, even when everything feels loud, rushed or hard to name.
Hold space for intense feelings without forcing an immediate, irreversible answer.
Share a need, not a whole explanation, when language collapses and reassurance is still needed.
Build a clearer picture over time so you can look back, make sense of patterns, and feel taken seriously later.
Everything below is designed to feel lighter on the hardest days: large actions, less typing, no guilt, and a calmer path from “what is happening?” to “what do I need next?”
Relationship-first. Irregular-cycle-aware. Built for the moments when it is hardest to recognise an episode from the inside.
Luteal feels like a safe space before it feels like a tracker. It starts with your data, your boundaries and your control.
The Today view helps you get your bearings quickly: what may be happening, what might help right now, and what can wait until later.
The journal works in layers: light enough for brain fog, detailed enough to become a record you can actually trust later.
When it is hard to tell whether this is a familiar difficult window, Luteal compares today to what has happened before and helps you find the gentlest next step.
Luteal notices pattern windows without pretending every cycle is predictable. It follows what your body and your record are actually showing, even when timing is mixed or unclear.
Partner mode helps you and your partner understand what is happening and move through it together, while keeping your experience, privacy and choices at the centre.
When everything suddenly feels relationship-ending, job-ending or life-upending, Luteal helps slow the moment down. It helps you and your partner put words around what is happening, hold onto perspective, and come back to big decisions with more clarity.
On harder days, Luteal brings back what has genuinely helped before, so support feels familiar, practical and close at hand.
Over time, the record becomes more than a journal. It becomes something you can trust, reflect on, and bring into conversations with a GP, therapist or specialist.
Safety is built into everyday use. Luteal helps you make a plan on steadier days and keeps things simple when you need help now.
Clear answers, plain language, and no pressure.
No. It is built with PMDD in mind, but it is also for people trying to understand other cycle-related shifts, irregular patterns and the impact these changes can have on mood, work and relationships.
That is one of the main reasons Luteal exists. The app is designed to help you notice familiar patterns, compare today with previous windows and reduce the pressure to make sense of everything from memory alone.
No. Luteal is designed to support without gaslighting. It can help with timing, urgency and next steps, and it does not dismiss what you are feeling.
No. Partner mode is entirely optional. You can use Luteal privately, share only certain things, or never invite a partner at all.
No. Guidance begins with your own data and your own experience. Partner thoughts stay separate unless you explicitly choose to include them in a specific piece of support.
Luteal is designed for that reality. Instead of pretending timing is exact, it aims to show pattern likelihood and confidence so you can spot meaningful trends without false certainty.
No. The app is there to help you notice patterns, document what is happening and make conversations with clinicians easier. It is not a replacement for diagnosis, treatment or emergency help.
Luteal quickly surfaces safety tools, trusted contacts and urgent-help routes. It can support a plan, but it does not replace emergency services or immediate clinical help.
Yes. Luteal is intended to stay free, with no ads, no subscriptions and no selling of sensitive personal data.
Built to help you stay oriented, stay safe and feel more understood through the days that suddenly become hard to carry.
