What's in the app
One dial. Your natural world.
Solunex™ shows a day as a single circle and layers what moves through it as rings. You can explore every one of them in the web preview.
Solar ring
Daylight and darkness, with sunrise, solar noon and sunset for where you are.
Lunar ring
Where the moon is and what shape it is, with moonrise and moonset.
Temperature ring
The shape of the day's warmth, hour by hour.
Air quality ring
How clean the air is through the day.
Year ring and compass
Where today sits in the year, which way you're facing, and which way to somewhere that matters.

Why natural time
Your clock doesn't tell you this.
Conventional clocks divide time evenly, regardless of seasonal or astronomical variation. Three examples of what that hides.
DAYLIGHT 14h 22mDAYLIGHT 9h 41m
The day changes length.
Usable light swings by hours across the year — and by location within the same time zone.
MOON 0.94 WAXINGMOONRISE 19:48
Night isn't uniform either.
Moonrise and phase change what an evening outdoors actually looks like.
Who it's for
Nature doesn't run 9 to 5.
Outdoors
Plan around real light, not the hour on your phone.
Daily rhythm
See how your daylight window shifts week to week.
Classrooms
A visual way to teach why the day changes length.
Simply curious
For anyone who's wondered why 6pm feels different in March.

What is the web preview?
A version of Solunex™ that runs in your browser. It's built from the same code as the mobile app, so you can see what the app will do while we finish it for phones.
Does it cost anything?
No. The web preview is free and needs no account, and pre-registering is free too. No products or subscriptions are sold at this time.
When will the mobile app be available?
We're working toward launch now. Pre-register and you'll hear the moment it's ready.
Which phones will it run on?
We're building Solunex™ for iPhone and Android.
What happens when I pre-register?
We'll email you product news, beta testing opportunities and launch offers. There's nothing to pay, and you can unsubscribe at any time.
Does the web preview use my location?
Only if you ask it to. The dial opens on a sample location; use its location button to switch to where you are, and your browser asks your permission first.
Does it work outside Las Vegas?
Yes. Solunex™ calculates from your coordinates. Las Vegas is where we're piloting demonstrations first.
