Quietly in your corner

Be the partner who just gets it.

Quvex gives you a calm, private read on where she likely is in her cycle — and the small, thoughtful things that tend to help. With her knowledge. On your phone. Nobody else's business.

What it does

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.

01

A calm daily read

Open the app and see, in a sentence, where she likely is — "energy rising", "winding down" — never a phase name or a verdict.

02

Small things that help

Two-to-four-word nudges — "stock supplies", "plan a low-key evening" — plus a song, a local spot, a message you can send.

03

Private by design

Everything stays on your phone, encrypted at rest. No account, no analytics, no avatars. Meaningful to you, invisible to anyone glancing over your shoulder.

04

Songs that fit the day

Song ideas she might actually like — matched to her taste and the moment, and tuned over time by listeners voting on what fits.

05

Words, when they're hard

Ready-to-send notes you can shape until they sound like you wrote them — with optional on-device polish on phones that support it. Nothing you write leaves the phone.

06

In her language

Quvex speaks 20 languages — with suggestions, songs, and food written for each culture, not translated word-for-word.

Your data, your money

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
Tuned by everyone

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.

Discretion, built in

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.

Not a medical device

The fine print, up front

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.
