Sundial: A Weather App That Shows You the Whole Day at a Glance
☀️ Try Sundial (web) · App Store · by Imran Zaidi
Most weather apps show you a vertical list of hourly rows. Temperature here, precipitation there, wind somewhere else. You scroll, scan, and mentally stitch together a picture of what the day actually looks like.
Sundial does something different. It visualizes the forecast around a 24-hour clock. Temperature and precipitation are plotted radially, so you can see at a glance how the morning compares to the afternoon, when the rain is expected, and how the temperature trends through the evening. One ring, one dial, the whole day.
What It Is
The web version at sundial.page is as bare as it gets. A text input for a city or postal code, a toggle for Celsius or Fahrenheit, and the dial. That is the entire interface. No accounts, no location permissions, no onboarding flow. Type a city and see the forecast.
The iOS app is 2.4 MB. That is not a typo. It supports iPhone, iPad, Mac (Apple Silicon), and Vision Pro. It collects zero data. Zero. The developer, Imran Zaidi, has a privacy policy that says “The developer does not collect any data from this app.” It requires iOS 15.0 or later.
The app includes haptic feedback when you scrub the dial between days. It was released December 31, 2025, and has been updated with support for locations in Japan, Korea, and China.
How It Handles the Problem
Every weather app has the same challenge. The data is complex and the screen is small. Most solve it by giving you more detail than you need behind tabs and menus you have to navigate. Sundial solves it by showing you less, better.
The 24-hour dial is a natural fit for how people actually think about weather. You do not care about the exact temperature at 2:47 PM. You care about whether the afternoon is warmer than the morning, whether it will rain during your commute, and whether evening will be cool enough for a walk. The dial answers all three at once.
The app also shows a full week of hourly forecasts on the same screen. You can scrub between days and see the shape of each one.
Why It Stands Out
There is a category of software made by one person who had a specific frustration and built exactly the solution they wanted. Sundial is in that category. It is small, fast, private, and opinionated about what matters. It does not try to be everything. It just does one thing well.
If you have ever opened a weather app and felt like you had to work to understand what the forecast actually means, this one is worth trying.
