GuideWatch
Guiding graphs from NINA
Free · Designed for iPhone. Not verified for macOS.
GuideWatch plots your PHD2 guiding graphs when you're imaging, and provides a moon phase complication during the day.
GuideWatch puts your PHD2 guiding session on your wrist.
If you run NINA to control your astrophotography rig, you already know the drag of walking back to the laptop every few minutes just to check whether guiding is still holding steady. GuideWatch connects directly to either PHD2 or NINA over your local Wi-Fi network and shows you what matters, right on your Apple Watch:
• Live guiding graph: see RA/Dec error trends update in real time, just like the graph in PHD2 itself
• RMS error and key guiding stats at a glance, with optional haptic alerts if guiding fails
• Simple connection status, so you know instantly if guiding has dropped out
• A quick settings screen to connect to PHD2 or NINA on your controller's IP address and port
No need to keep walking back to a screen, break your dark adaptation, or leave a laptop running somewhere inconvenient (just glance at your wrist).
GuideWatch also includes a simulation mode, so you can explore the app and its guiding display before connecting it to a live session.
Requirements: GuideWatch needs either PHD2 or a NINA instance with the Advanced API module running on the same local network. GuideWatch does not control PHD2, NINA or your imaging session; it's a read-only guiding monitor designed to keep you informed without needing to touch your imaging laptop.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Added support for accessing guiding information from PHD2's own API. This means you can use GuideWatch to monitor guiding anywhere PHD2 is used, not just when it is paired with NINA.
