Everything you need to get the Kayserlich app working — and a direct line to the developer.
Write to the developer directly through the contact form. There is no call centre — messages go straight to the person who builds the app.
You can also reach the same form inside the app under Settings → Send a message, which attaches your app version and device model so problems are easier to reproduce.
No. The app is free and shows live data from a real Davis weather station straight after installation — no account, no setup. Connecting your own station is optional.
The annual subscription unlocks it. In the app go to Settings → Weather station setup and enter the API key and secret from your WeatherLink account at weatherlink.com. The app checks them immediately and only saves them once they work.
It is an auto-renewing subscription with a term of one year. The exact price in your currency is shown by the App Store before you confirm the purchase.
Subscriptions are managed by Apple, not by us. On your iPhone open Settings → your name → Subscriptions, choose Kayserlich and tap Cancel. Access continues until the end of the paid period.
No tracking, no advertising, no analytics. Your station credentials stay in the iPhone Keychain on your device. Only a message you send through the contact form leaves the app, and only with the details shown to you before sending.
