Be the partner who just gets it.
A calm, private sense of where she likely is — and the small, thoughtful things that help. With her knowledge, on your phone.
Care, translated into plain language.
No charts to decode, no clinical jargon. Just a gentle read on how she's likely feeling — and one or two things you can actually do today.
A calm daily read
One sentence a day on where she likely is — "energy rising", "winding down". Never a phase name or a verdict.
Small things that help
Short, doable nudges like "stock supplies" or "plan a low-key evening" — plus a song, a spot, or a message to send.
Private by design
Everything stays on your phone, encrypted at rest. No account, no analytics, no avatars. Meaningful to you, unreadable over your shoulder.
Songs that fit the day
Song ideas she might actually like — matched to her taste and the day, tuned by listeners voting on what fits.
Words, when they're hard
Ready-to-send notes you shape until they sound like you wrote them. Nothing you write ever leaves the phone.
In her language
Quvex speaks 20 languages — suggestions, songs, and food written for each culture, not translated word-for-word.
None of this is certain. Every read is an estimate from the dates you log — a careful guess, never a verdict — and Quvex tells you plainly when it isn't sure.
Free forever. Yours alone.
On your phone. Nobody else's. Always
Everything lives on-device. No sign-up, no cloud copy, no network identity — your cycle data never leaves your phone.
- No account, ever
- No analytics or ad SDKs
- Encrypted at rest on the device
- Export and restore a backup anytime
Free means free.
Every feature, for everyone, at no cost. The developer funds it himself — and the running cost stays tiny because your data never touches a server.
- No ads, subscriptions, or in-app purchases
- No commissions — recommendations are never paid placement
- We never sell data. We couldn't — we don't have it
Fun fact: a fair chunk of Quvex's foundational code — and the playbook later AI helpers have followed — was written by an AI model called Fable 5, in its original 3 day incarnation, before the US government ban. Make of that what you will.
Nobody needs to know but you two.
The app is named just "Quvex". Nothing on a lock screen, a notification, or the app switcher ever hints at what it's for.
- No cycle words on any lock screen
- No names, photos, or avatars
- Screenshots blocked on release
- One neutral daily check-in
- No backups carry your data along
- Added only with her knowledge
Glance at the day, on your glasses.
Send today's cue to Meta Ray-Ban Display glasses and read it as one quiet shape — a square, a ring, or a circle — that only you can see. Your phone does the thinking; the glasses only show the shape.
A developer preview: it stays off until you turn it on, and we have not yet confirmed it on hardware in every region. The preview below is a simulation, not a photo of real glasses.

The community makes it better.
Some of what the app suggests is shaped by anonymous votes on this site — no account, no names, just people saying what actually helps.
Song board
Vote on which songs are good — and which days of the cycle they fit. The app picks better songs because of it.

Honest about what this is.
Quvex is not a medical device. It doesn't diagnose, treat, or prevent anything, and makes no contraceptive or fertility claims. Predictions are statistical estimates from logged dates and can be wrong. Educational facts are sourced and hedged to the strength of the evidence. Nothing here is medical advice — don't use Quvex to plan or avoid pregnancy or to make any health decision.
