She tracks.
He finally gets it.

Soleii is the cycle app built for two people. She logs her days. He wakes up already knowing what kind of day it is.

🎉

You're on the list!

Welcome to the Soleii family.
Your soul animal is warming up just for you.

One app · two sides

Two people. One cycle.
Finally on the same page.

Every other period app hands her a calendar and leaves him guessing. Soleii gives you each your own screen, wired to the same days.

Her side

A cycle that finally makes sense

Phase, forecast and fertility at a glance. Log a symptom in one tap and the whole week updates around it.

  • Period, follicular, ovulation and luteal, always current
  • Daily insights written for how today actually feels
  • Ask for a hug, a coffee or a call without explaining why

His side

Show up without being told

He never sees her raw logs. He sees what to do about them, in plain language, on the day it matters.

  • Today's one thing, phrased so it's easy to act on
  • A phase playbook that changes as her cycle moves
  • Send a heart in a tap when words won't come out right

How it works

Four taps to a
calmer month.

01 / TRACK

She logs. Once.

Mark the first day and Soleii does the rest. Phase, next period and fertility window recalculate the moment anything changes.

02 / SEE

The whole month, at a glance.

A calendar that reads like a story instead of a spreadsheet. Logged days, predicted days and the week ahead, colour coded.

03 / SHARE

He gets the translation.

Not her data. Her context. One clear thing to do today, plus a playbook for the phase she's actually in.

04 / ASK

Send a Sunflare.

Rough day and no energy to explain it? One tap sends him a gentle alert with the exact words to reply.

Sunflare

The button for the days you can't find the words.

One tap tells him you need something. He gets a nudge, a tip, and a line he can actually send back. No fight, no guessing, no "what's wrong?"

no app talks about.

For the days you're exhausted before you open your eyes — he already knows.

One plan. Two people. The first period app built for both of you.
