Frequently Asked Questions
What is Uptime Kuma?
Uptime Kuma is a free, open-source, self-hosted monitoring tool. You can monitor HTTP, TCP, DNS, and other services. KumaAlert connects to your Uptime Kuma instance to show monitor status on your iPhone, iPad, and Android device. Learn more at
github.com/louislam/uptime-kuma
Is there a free trial?
Not at this time. KumaAlert is a one-off purchase at a low price, with no subscription, no recurring fees, and everything unlocked forever. Most apps of this kind lock features behind monthly plans, but that felt at odds with the self-hosted spirit of Uptime Kuma. That said, running the push notification infrastructure and maintaining an Apple Developer account does have a real cost, which is why there's a small one-time charge rather than a free tier.
Why can't I connect to my server?
Check that: your Uptime Kuma server URL is correct and includes https://, your server is accessible from the internet (not just your local network), your username and password are correct, and your server is running Uptime Kuma v1.23.0 or later.
How do push notifications work?
KumaAlert uses your Uptime Kuma server's notification system to send push alerts via Apple's Push Notification service. You'll need to set up a notification provider in your Uptime Kuma dashboard that points to KumaAlert's push relay.
Can I monitor multiple servers?
Yes! KumaAlert supports connecting to multiple Uptime Kuma instances. Add additional servers from the Manage tab in the app.
What does the API key do?
The API key lets KumaAlert check your monitors' status in the background, while the app isn't open. This is what keeps the Home Screen widget up to date. Without a key, the widget only refreshes when you open the app. Generate an API key in your Uptime Kuma dashboard under Settings > API Keys, then add it in the app under Settings > your server > API Key.
Why doesn't my Home Screen widget update on its own?
The widget refreshes in the background using an API key. If you haven't added one, it can only update when you open the app. Add a key under Settings > your server > API Key (generate it in Uptime Kuma under Settings > API Keys). Note that the operating system decides exactly when background refreshes run, so updates are periodic rather than instant.
Is my data secure?
Yes. All credentials are stored in your device's secure keystore (iOS Keychain / Android Keystore), and monitor data stays on your device. See our
Privacy Policy for full details.
