Support

Email support@foureyes.xyz with the app's name and a quick description of what's happening. A screenshot or your device and iOS version helps me track things down quickly.

It's just me building these apps, but I usually reply within a day or two.

Most Four Eyes apps store everything on your device, so deleting the app removes its data. Many apps also offer a reset or delete option in their settings. See the Privacy Policy for per-app details.

All purchases are handled by Apple, so refunds go through them at reportaproblem.apple.com. If something went wrong, email me too and I'll do what I can to help.

No. Every sun and moon time is computed on your device from astronomical math. Solunar works in airplane mode, deep in the backcountry, and miles offshore—no signal required.

Major periods are the windows around the moon's overhead and underfoot transits—usually the strongest feeding activity. Minor periods occur around moonrise and moonset. Solunar shows both for any date and location.

No. Location access is optional and used only on your device to compute local times. You can add any spot manually under the Spots tab. Your location is never transmitted off your device.

No. Solunar is a one-time purchase with no ads, no accounts, and no subscriptions.

Sun and moon times are computed with standard astronomical algorithms (Meeus) and validated to within about a minute against the U.S. Naval Observatory across a wide range of latitudes.

Open Settings inside Solunar and turn on "Alert before major periods." Reminders are scheduled locally on your device a few minutes ahead of each major window.
