Your domains,
watched while you sleep.
Domain Night Watch checks your domains every 6 hours and alerts you when something changes or is about to run out. Add up to 10 domains, switch on night watch, and get on with your day.

Features
What it watches
The first check of a domain only records its starting state, so you aren't flooded with alerts on day one.
Name servers and mail servers
An alert when the name servers (NS) or mail servers (MX) change.
SPF and DMARC
An alert when a record changes or is removed.
Website certificate (TLS)
Alerts 30, 14, 7, 3 and 1 days before it expires, or when there is an error.
Domain registration
Alerts 60, 30, 14, 7 and 1 days before it expires.
Alerts that respect your night
Normal alerts wait until your quiet hours are over. Serious ones always come through: a certificate error, a certificate with less than 3 days left, a registration with less than 7 days left, or all mail servers gone.
Face ID lock
Lock the app with Face ID if you like.
Subscription
One subscription. Everything included.
Try it free for 7 days. After that, it costs $0.99 a month or $7.99 a year (US dollars; the App Store shows your price). There is no free version. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. You can manage or cancel it in your App Store account settings.
Your subscription is bought, billed and cancelled through your App Store account. We never see your payment details.
Safety first
What it does with your data
The app only looks at public DNS, certificate and registration information. It never logs in to your domains and can't change anything.
To send alerts: your iPhone's notification token, the domain names you added, the last result of its checks, your settings, your language and your time zone. We delete all of it when you turn night watch off, or after 60 days without opening the app. There is no account and no login.
Domain Night Watch gives you technical information about your domains. It is not a security guarantee. Results and alerts can be late, for example when Apple's push service, Focus or Low Power Mode holds them back.
