Smile Day: Turn Weather Data into Practical Daily Advice
We use weather apps every day, but they often only provide numerical information such as: 26°C today, a force 4 north-easterly wind, a 40% chance of rain…

What we really need, though, is practical advice: should you wear long or short sleeves today? Do you need to take an umbrella? Will it suddenly turn colder when you leave work this evening? If you’re travelling to another city for work, what extra clothing should you bring?
The iOS app Smile Day, launched this week, aims to solve precisely these problems. It is a weather app that turns weather data into clothing, travel and protection advice, and is now available from the lizhi.shop software store.

Smile Day offers a free trial. Once upgraded, it unlocks a wealth of features, including weather alerts, detailed clothing and protection advice, and personalised appearance options.

No more working out the weather yourself
Many weather apps simply give you a long list of figures for temperature, wind speed, humidity, air pressure and more. After reading them, you still have to work out for yourself: “So how should I respond?”
Smile Day takes this data and turns it into easier-to-understand feels-like conditions and practical advice. For example, it can tell you directly what to wear today, whether you need sun protection, whether to bring an umbrella, and which weather conditions are worth paying particular attention to.
Even data such as “air pressure 1,000 hPa” and “force 4 north-easterly wind, 22 km/h” is accompanied by explanations such as “the weather may be changeable” and “like having a small fan blowing”, making weather information feel more like everyday advice than a cold data sheet.

Automatically check tomorrow in the afternoon
There is another easily overlooked problem with weather forecasts: in the morning, you care about today, but by the afternoon, what you really want to know has already become tomorrow’s forecast.
For example, when you’re preparing to leave work in the afternoon, being told “how much colder today is than yesterday” or “what you should wear today” is no longer particularly useful. More valuable at that point is knowing whether tomorrow will be colder than today, what to wear and whether you need to prepare an umbrella in advance.
Smile Day lets you set an automatic switching time for feels-like comparisons. Once the specified time is reached, the feels-like changes, clothing recommendations and other content on the home screen can automatically switch from “today” to “tomorrow”, reducing the need to browse through forecasts manually and compare the data again.

Compare temperature differences between cities at a glance
Before setting off on a business trip, we often encounter another problem: the destination shows 18°C, but exactly how much colder is 18°C than where I am?
Smile Day also supports a city comparison feature. After searching for another city, you can directly compare its temperature and weather with those of your current city, without switching between pages and calculating the temperature difference yourself.
This feature is useful not only for business trips and holidays, but also for keeping an eye on family and friends in other locations. For example, if it is 32°C in Chengdu but only 14°C in Melbourne, you can immediately see that it is noticeably cooler where the other person is and remind them to wear warmer clothes.

Resolve your out-and-about concerns in three seconds
Smile Day is designed to give you genuinely useful answers in just a few seconds wherever possible.
The home screen prioritises feels-like changes, weather tips, and clothing and travel advice. If there is rain, a significant drop in temperature or another weather condition requiring attention, it will be highlighted directly, so you do not need to study the full set of weather data first.
If you do want to view detailed information, simply open the details page to see a 10-day forecast, historical weather, a calendar timeline, a 10-day trend chart and more, creating a “minimal first, comprehensive later” experience.

Customise it to suit your habits
Different users have different habits when checking the weather. Some only want to know what to wear, while others pay attention to wind strength, air pressure and rainfall trends. That is why Smile Day offers a range of customisation options.
The modules on the details page can be rearranged and switched on or off, while the home-screen background and text can be changed. Notification times, notification types, numerical thresholds and clothing recommendation schemes can also be configured to suit your personal habits.

Paid users can also choose Apple Weather / Caiyun Weather as the data source, unlocking detailed weather tips, more notification options, custom home-screen image backgrounds, and appearance settings such as widget background modes, opacity and font colour.
Smile Day currently offers clients for iPhone and iPad, and also supports quick access to weather information via Mac desktop widgets, Apple Watch and other methods.

Final thoughts
If you also feel that a weather app should not simply be filled with complicated data such as temperature, humidity and the chance of rain, but should directly tell you “how to head out today”, then Smile Day is definitely worth trying!
The app supports a free trial. Upgrading unlocks a wealth of features, including weather alerts, data-source selection, detailed clothing and protection advice, and personalised appearance options.
