Concept · 2026
A weather app for people who wake up in one city and land in another by Thursday, and for people planning a month ahead.
01 · Overview
Weather apps are built for people who stay put: one city, one forecast, today. But the people who need weather most, the ones with 6am flights and a carry-on that has to work in two climates, end up stitching answers together across apps and doing time zone math before coffee.
How might we let someone living across three cities understand all of them at a glance?
Daily Summary
Good morning, Iris. It’s 31° and sunny, ranging from 28° to 34° today.
02 · The Users
The primary user is a frequent traveller who needs three cities at a glance, not one after another. The secondary user is a long-term planner whose livelihood depends on whether the next three weeks stay dry. The design had to serve both without shortchanging either.
Primary user
Thinks in hours
Maya, 31Business Development Managerher situation
Flies 3–4 times a month across North America and Asia. Lives out of a carry-on. Always has three time zones open in her head.
her goal
Know what to pack for Tokyo on Thursday, without opening four apps to figure it out.
her frustration
“I do the timezone math in my head before I’ve had coffee. Every. Single. Morning.”

Thinks in seasons
Daniel, 48Independent Farm Ownerhis situation
Runs 200 acres in the Fraser Valley. Planting and harvest windows are everything. One bad weather call costs him weeks.
his goal
Find the dry windows in the next 3–4 weeks. Trends matter more than today's number.
his frustration
“Every app shows me today. I don’t need today. I need the next month.”

03 · Key Decisions
Every city gets its own colour. Vancouver is a warm sunny yellow, Boston a cool sky blue, Tokyo a muted night slate. Tap a colour and the whole screen follows: colour tells you where you are before you read a word.
Daily Summary
Good morning, Iris. It’s 31° and sunny, ranging from 28° to 34° today.
Now, switching cities feels like walking into a different room.
The time difference sits right under the city name. “+3h from local” and “+16h from local” take the mental math out of Maya’s morning.
Daily Summary
Good morning, Iris. It’s 31° and sunny, ranging from 28° to 34° today.
Now, there’s no converting in your head before coffee.
Five days, three facts each. Every forecast row leads with the day, the conditions and the high and low. Hourly breakdowns were left out on purpose: they add load without helping someone pack a bag.
Daily Summary
Good morning, Iris. It’s 31° and sunny, ranging from 28° to 34° today.
Now, the forecast answers the packing question in one glance.
A Daily Summary in plain language. Above the numbers, a short greeting reads the day for you: how it feels, the range and the conditions, like a friend checking the weather for you.
Daily Summary
Now, you get the meaning first and the numbers second.
Monthly transforms the screen you’re already on. Tapping “Monthly” swaps the 5-day list for a 30-day outlook, a temperature range chart and a precipitation forecast, so Daniel can spot dry windows without a separate app.
Daily Summary
Good morning, Iris. It’s 31° and sunny, ranging from 28° to 34° today.
Now, one app serves both a 6am flight and a harvest plan.
Locations you can rearrange by hand. Each city card is tinted with its colour, shows its offset and temperature, and can be dragged to reorder or removed. A search bar, with voice, adds new ones.
Locations
Now, your three cities are always one swipe apart, in the order you care about.
04 · Outcome
3cities at a glance
2users, one screen
6screens designed
Every element in Wayther (the city colours, the offset, the five-day format, the summary, the monthly toggle) traces back to a specific person with a specific problem.
