About Flat Earth Sun & Moon Clock
I’ve been curious about flat earth models for a while, but most resources are just videos or forums. When I stumbled on the Flat Earth Sun & Moon Clock app by Blue Water Bay, I was skeptical but paid the $2.99 to see if it could actually visualize the concepts. After using it for a few weeks, I’m impressed. It’s not a debate tool; it’s a functional clock and tracker built from a specific perspective, and it does that one job really well.
Features & Highlights
The core feature is the main clock view. It shows a beautiful, stylized flat earth map (the Azimuthal Equidistant projection) with the sun and moon as moving dots. I use this every morning. Instead of just a time, I can see if the sun is over the Atlantic or approaching my location. The day/night terminator line is clear, and tapping on the sun icon gives me exact sunrise and sunset times for my town, which have been accurate.
I didn’t think I’d use the zodiac clock much, but it’s neat. It’s a circular wheel showing the current constellation behind the sun. As a feature, it’s simple—it just shows the sign and its symbol—but it integrates smoothly. The moon phase tracker is detailed, showing not just a picture but the moon’s position on the flat earth map and its illumination percentage. For someone trying to understand the flat earth model’s explanation for these cycles, having them all in one place is invaluable.
User Experience
The first time I opened the app, I just stared at the animation. Seeing the sun move in a perfect circle over the flat disk, tracing what the app calls the “tropic lines” throughout the year, made the theory click for me visually. Zooming in and out on the map with my fingers is smooth, and I often drag the map to see what time it is in other parts of the world according to this model.
There was a specific moment last weekend. I was camping, and I wanted to know when true dark would set in. I opened the app, saw the moon’s dot was just below the horizon on the map, and it gave me a “moonrise” time. It was spot on. That practical use, regardless of the cosmology behind it, proved its utility to me. The interface is clean, with no cluttered menus. Everything is tap or drag.
Pricing
This is a paid app at $2.99 with no in-app purchases or subscriptions. For a niche tool like this, I think the price is fair. You’re paying for a specialized piece of software without ads or data tracking. Compared to free astronomy apps that push a globe model, this offers a unique perspective you simply can’t get elsewhere. If you’re genuinely interested in the flat earth model, it’s absolutely worth the one-time fee. If you’re just curious, maybe watch a video demo first.
Updates & Support
Looking at the update history on the App Store, the developer, Blue Water Bay, updates the app once or twice a year. These usually seem to be for compatibility with new iOS versions or minor bug fixes. The app is stable, so I haven’t needed support. There’s no in-app chat, but the developer lists a support email on the store page. For a small, niche app, this level of maintenance is pretty standard and acceptable.
Security & Privacy
I downloaded this directly from the official Apple App Store. The app’s privacy label on the store states that no data is collected from you at all—not usage data, not location (it uses location services only if you grant permission for accurate sun times for your spot, but it doesn’t store or send it), not identifiers. I verified this in my iPhone’s settings. The app has no ads, no analytics, and doesn’t require an account. It’s as private as an app can be, which is a big plus.
What does the main clock view in the Flat Earth Sun & Moon Clock actually show?
The main view displays a stylized flat earth map using the Azimuthal Equidistant projection, with the sun and moon moving as dots. You can see the day/night terminator line, tap the sun icon for accurate local sunrise and sunset times, and zoom or drag the map to check the time in other parts of the world.
Does the app include any features beyond just a clock, like moon phases or zodiac info?
Yes, it includes a zodiac clock that shows the current constellation behind the sun, and a detailed moon phase tracker that displays the moon's position on the flat earth map along with its illumination percentage. All these tools are integrated into one interface, making it easy to explore the flat earth model's explanations for these cycles.
Why isn't the sun or moon moving on my screen, or why are the times wrong?
First, make sure your device's date and time are set to automatic and your location services are enabled. If the animation still seems frozen, try restarting the app or checking for an update in your app store, as the clock relies on real-time data synced to your time zone.
The app keeps crashing or is very slow when I zoom in and out on the map. What can I do?
This usually happens if your device is low on storage or has an older processor. Try closing other apps running in the background, clearing the app's cache in your phone settings, or reinstalling the app. If the problem persists, your device may not meet the minimum requirements for smooth map rendering.
How does the Flat Earth Sun & Moon Clock compare to standard astronomy apps like Stellarium or SkyView?
Unlike standard astronomy apps that use a heliocentric globe model, this app is built entirely from a flat earth perspective, showing the sun and moon moving in circles over a flat disk. It's not designed for stargazing or deep space objects; instead, it focuses on providing a functional clock and visual tracker for those curious about the flat earth model's explanation of day, night, and seasons.
