Download & sign in

Get the app

MianBiwi is available on the App Store for iPhone. Search for MianBiwi or use the download link on mianbiwi.com. An Android version is in the works.

Create your account

When you first open the app you'll be asked to sign in. You can:

• Sign in with Apple — the fastest option on iPhone, and it keeps your email private.
• Sign up with email — enter an email address and a password.

Each spouse creates their own account on their own phone. You'll link the two accounts together in the next step — you do not share one login.

Your private couple

The moment you sign up, MianBiwi quietly creates a private "couple" space just for you. If you use the app solo, that's all you need. When you pair with your spouse, your two spaces merge into one shared couple.

One person, one couple. Each account can belong to only one couple at a time. If you ever need to switch, you leave your current couple first (see Pairing).

App Lock (Face ID)

Because MianBiwi holds personal and financial details, you can lock the whole app behind Face ID / Touch ID. Turn it on under Settings → App Lock. When enabled, the app asks for your face or fingerprint every time you open it. See App Lock & security.
