Xulo vs WonderPush · Updated 8 October 2026
A device that has not opened the app is not on the bill.
WonderPush, checked on docs.wonderpush.com on 8 October 2026, charges €1 a month for 1 to 1,000 subscribers and another €1 for each further thousand. A subscriber is a device that opted in. Opening the app is not part of that definition. An empty account is €0, and there is a 14-day trial. Xulo does not start the meter at the first opt-in. A monthly active user opened the app in the last 30 days.
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 first device
The first 1,000 monthly active users on the app are $0.
€1 for the first 1 to 1,000 subscribers. Zero subscribers is free.
Who is a subscriber
A monthly active user: the app was opened in the last 30 days. Push permission is not required. Each app has its own count.
A device that opted in. The same device on two apps counts twice, for the organization.
A device that stays closed
Not a monthly active user, so not on the bill.
Still a subscriber, still on the invoice.
When the stickers cross
$6 once an app has 1,001 to 2,000 monthly active users. Cheaper on their side when those opted-in devices also opened the app. A device that opened and refused push is on this bill and not on theirs.
€2 for 1,001 to 2,000 opted-in devices.
A/B test
Two variants of a push or a card, split evenly. A person approves. The card records impressions, dismisses, and button clicks for each variant.
Variants of one notification. Sent and clicked can be compared per variant.
Local time
A scheduled push uses the device timezone, read when the app opens. Not location, and not the network address.

They are subscribers there. They are not monthly active users here, so they are not on the bill.

Their first thousand already costs €1. Ours is still inside the free thousand.

€2 against $6. This is the row where the counts match. The moment some of those 1,600 stop opening the app, they stay on the WonderPush invoice and leave the Xulo invoice.

The same device in two apps is two subscribers on their organization. 1,600 subscribers is the €2 step. Each Xulo app is its own free thousand.
Opt-in is not the same event as an open
WonderPush defines a subscriber as a device that agreed to receive notifications. Unsubscribed devices are excluded. The definition does not ask whether the app was opened this month.
A monthly active user is a device that opened the app in the last 30 days. Push permission is not required. A device that opted in and then went quiet drops off after 30 days, and stays on the WonderPush bill. A device that opened and refused push is the other way around: it is a monthly active user here, and it is not a subscriber there.
The €1 steps are real
Their table is linear: €1, €2, €3, and so on, one euro per thousand subscribers, starting at the first subscriber. A 14-day trial comes first. After that, an app with users is on the table.
On a list where every opted-in device also opened the app, 1,600 people is €2 there and $6 here. Xulo is the lower bill when part of the list has gone quiet, and when a second app would otherwise be added onto the same subscriber total.
Questions
Does Xulo charge for a subscriber who never opens the app?
No. A monthly active user opened the app in the last 30 days. An opted-in device that stays closed is not on the bill. WonderPush still counts that device as a subscriber. A device that opened and refused push is counted here and is not a WonderPush subscriber.
Where does the WonderPush price on this page come from?
docs.wonderpush.com and wonderpush.com/pricing, checked 8 October 2026. €1 per month for 1 to 1,000 subscribers, then €1 more per thousand. A subscriber is an opted-in device. Zero subscribers is free, and there is a 14-day trial.
Is Xulo cheaper than WonderPush at 1,600 opened devices?
No. If all 1,600 opted in and opened the app, WonderPush is €2 and Xulo is $6. Xulo is the lower bill when some of those devices stop opening the app, because they leave the monthly active users and stay on the subscriber count.
Do two WonderPush apps share one subscriber total?
A subscriber is a device plus an app, and the organization is billed on that total. Two apps add together. On Xulo each app has its own 1,000 free monthly active users.

The other two meters.
Vs OneSignal
A $19 fee on the organization. A free thousand on each app.
Growth, checked 8 October 2026, is $19 a month plus $0.012 per monthly active user. At 1,600 monthly active users on one app, that is $38.20 against $6.
Compare with OneSignal
Vs Pushwoosh
Every app keeps its own first thousand.
Push only is $7 per 1,000 on the account, and that free thousand is shared. Two apps at 800 each are one pool there. Here each app is inside its own free thousand, so both are $0.
