Install InBetween

What InBetween does

InBetween helps you keep track of how you feel through perimenopause and menopause. On most days you answer a short check-in, about a minute of questions on mood, sleep, hot flushes and more. InBetween turns your answers into simple patterns over 14, 30 or 90 days, and into a clear summary you can bring to your next doctor’s visit. Your answers stay on your phone.

Works on iPhone with iOS 26 or newer, and on Android 12 or newer.

InBetween isn’t in the App Store yet. Apple shares early apps through its own free app, TestFlight. Here is exactly what will happen.

  1. Tap the invitation

    Tap the button below. A page from Apple opens.

    Open InBetween invitation

  2. Get TestFlight (first time only)

    If you don’t have TestFlight yet, Apple’s page takes you to the App Store. TestFlight is free and made by Apple. Tap Get, install it, then come back here and tap the invitation again.

  3. TestFlight installed? Reopen your InBetween invitation

  4. Accept and install

    TestFlight opens and shows InBetween. Tap Accept, then Install.

  5. Open InBetween

    InBetween appears on your home screen like any other app, with the teal iB icon. Open it from there.

Good to know

  • TestFlight is simply Apple’s way to share an app before it’s in the App Store.
  • You don’t need an account with us.
  • When we release an update, TestFlight lets you know and installs it.
  • InBetween is still in development. I'm doing my best to protect your privacy, but as with any early app, security isn't final yet, so share only what you're comfortable with.

Why installing works this way

You’re joining a small pilot. We’re testing the experience with a few people before InBetween goes to the App Store and Google Play. That’s why iPhone uses Apple’s TestFlight and Android uses a direct download. Tell us what’s confusing or missing: your feedback shapes the app.

Optional. We send one email explaining how InBetween works and how to reach us. We don't add you to a list.

An early beta, not clinical care

InBetween is still in development. I'm doing my best to protect your privacy, but as with any early app, security isn't final yet, so share only what you're comfortable with. Do not use this early beta for clinical care.
