Each app counts its own MAU.
On the bill, and off it.
A monthly active user is a device that opened the app in the last 30 days.
Not counted
- The app stayed closed for 30 days. Push permission does not keep it on the bill.
- Installed, and never opened.
- A second app. It has its own 1,000.
01
The notification
A push carries a title, a body, an image, and a link. The image is attached on the device. If the image fails, the text still arrives.
The link can be a screen inside the app or an https address. The app opens the screen when it knows the address. Otherwise an https link opens in the system browser.
- Expanded view shows the large image, the title, the body, and a button.
- The app decides which screen opens.

The card inside the app
The card is drawn natively in the app. It can show when the app comes to the foreground, or when the app calls a name you set. An open is coming to the foreground. Coming forward again while the app is already open does not count. The call is one line of code at the moment you choose, and it is not stored. It is not a web page, and it is not sent through Apple’s push service.
The panel and an agent fill the same record: image, title, body, one button, link, colors, a close button, and a place. The place is the center, full screen, a top banner, or a bottom banner. One card shows at a time. If several match, the newest published card wins.
- Once, on the next open.
- On every open.
- On the first open only.
- On the open you number, once.
- After a specific push, on the next open of devices that received it.
- When the app calls a name you set. Once on that device, or on every call.

Who receives it
Push and the card use the same audience. A segment, a tag, an external id, the install id, or a test device.
Xulo keeps an install id that survives a token refresh. A reinstall gets a new one. An external id is optional and does not replace the install id. Tags are text keys and values the app writes.
A purchase is an amount, a currency, and an order id. The person page keeps the lifetime total for each currency. A segment picks the last 24 hours, the last 7 days, the last 30 days, or all time: people who spent, people who did not, or people who spent at least an amount in one currency.
- Subscribed.
- Opened in the last 7 days.
- Not opened for 30 days.
- Spent at least an amount, in a window.
- Test devices.
- Then language, country, app version, and tag.

Who comes back
The panel keeps the day a device first opened, and the later days it opened. For devices first seen on one day, it shows the share that opened the app again on day 1, on day 7, and on day 30.
That is the last-open record, kept by day. It is not how long a session lasted. It is not a custom event. It is not a list of people.
- Day 1.
- Day 7.
- Day 30.
- Not a person list.

A person sends
The panel, or an agent in Continue, Cursor, OpenAI, Windsurf, Anthropic, Google Antigravity, or Cline, can draft the message, the audience, and the card. The draft includes a count of who would receive it. One address works in all of them.
A person says yes. Then it sends. Writing the draft does not send it. The bill stays per app even when one key can draft for every app in the account.
- An existing mobile push list can be brought into the panel.
- Crossing 1,000 monthly active users does not stop the app.
- Two variants can share one send. The audience is split evenly.
- A scheduled push can arrive at a local time on each device.

What people ask before they start.
What does Xulo do?
It sends mobile push and shows a native in-app card. One SDK, one audience. The bill is per app, on monthly active users. The first 1,000 monthly active users on an app are free. After that, $6 per 1,000. Apps do not pool.
Does a new app pay?
A new app starts free. With no users there is nothing to bill. The first 1,000 monthly active users on that app stay at $0. The meter starts when a device opens the app. Push permission is not required.
What counts as a monthly active user?
A monthly active user is a device that opened the app in the last 30 days. Push permission is not required. A device that refused push and still opened the app is counted. A device that stays closed for 30 days drops off, even if push is allowed.
Do several apps share one free allowance?
No. Each app has its own 1,000 free monthly active users, then its own $6 blocks. A second app at 400 is $0 even when the first app is already paid.
Are in-app impressions billed?
No. Impressions, dismisses, and button clicks are not a separate charge. A device that opened the app in the last 30 days is already a monthly active user, including when it refused push.
Can an agent send it?
Add https://mcp.xulo.io/mcp. The tool opens a sign-in screen, you allow it, and it comes back. The agent can create the app, store the Apple key, draft a push or an in-app card, and import an audience. A person says yes. Then it sends. Writing the draft does not send it.
Can I start today?
Sign in and add an app. A new app starts free. With no users there is nothing to bill. The first 1,000 monthly active users on that app stay at $0.
Can a send be two variants?
Yes. A push or the card can be two variants, split evenly. A person still approves. Xulo does not pick a winner.
