A phone-first weather app built to answer “what do I actually need to know?” at a glance — one screen, no clutter, no account, no ads.
📱One screen, portrait-first.The whole picture fits without scrolling.
🗣️Plain-language outlook.“Rain likely around 3 PM,” from the hourly data. When it’s dry, it counts days until rain returns — the next day with a ≥50% chance or ≥1 mm total. A “+” (e.g. “6+ days”) means that day has ≥1 mm but under 50% chance, so it likely stays dry longer. It names the type — rain, snow or both — and says when it changes over, e.g. “Rain turning to snow, easing by 9 AM”.
↔️Swipe through time.Hourly (48 h back, 72 h ahead) and daily (7 days back, 16 ahead) strips — swipe on a phone, or click-and-drag on a desktop. Once Now or Today is off-screen, a yellow NOW button above the scroll bar brings you back. Each day’s low and the icon beside it, in the darker band, are the night that follows it, evening to the next morning.
📈Tap an hour or a day.Opens a Conditions chart — that day’s hourly temperature and feels-like as two lines, with a day picker to swipe across the full 16-day forecast (and two days back). A fixed centre cursor reads the exact temperature, feels-like, and precipitation (rain in mm, snow in cm, and the chance) for the hour under it, with a yellow ← NOW button to jump back; a precip band sits below.
📍Find any place.Search a city or street address, or open the map and tap anywhere to forecast that exact spot. It reopens the last place you viewed, and once you’ve saved a few places, swipe the summary card sideways to slide the whole forecast to the next place (it’s already loaded, so it follows your finger); its name sits at the top of the card, with dots under it showing which of your places you’re on. To change the order, press a saved place in the search panel and drag it up or down. Once you’ve used “my current location”, it joins the list too — first, with a ring-shaped dot — whenever you’re more than 25 km from every saved place.
👆Tap for more.A small + in the margin marks the summary lines you can open — Wind, Air Quality, Moon, and Daylight.
💧Precipitation you can see.Flat bars on one straight scale — twice the amount, twice the height — so bars compare at a glance, and bars with the same label are the same height. The scale stays fixed so heights mean the same every day; only when an extreme event goes past its top does that strip stretch to fit it. Rain is blue, labelled in mm, and fainter when it’s less likely; snow is always white, labelled in centimetres of fresh snow (about 7 cm per 10 mm of water). A day with both stacks them, rain under snow, with both amounts. A label too big for a short bar sits just above it. Snow, freezing rain and rain-and-snow get their own icons, and an icon’s strength (light or heavy) follows the amount shown.
🌬️Wind & gusts.The summary shows the current wind and gust with an arrow pointing the way it blows. Tap the “Wind” line for an hourly graph from two days back to 16 days ahead — slide it under the fixed centre line, like the Conditions chart, with Light→Severe bands, direction arrows, a day picker, a readout of wind, direction and gust for the hour under the line, and a yellow ← NOW button to jump back.
👉Slide from anywhere.On the Moon, Daylight, Wind and Conditions panels, drag sideways anywhere on the panel to move through time — a flick keeps it going. Yellow marks now on each one.
🫁Air quality.A colour-coded air-quality index — Canada’s AQHI (1–10) for Canadian locations, the US AQI everywhere else. Tap the “Air Quality” line on the summary for the details — a scale showing where your reading sits among all the categories, what the category means, and a breakdown of pollutants like PM2.5 and ozone.
🌙The Moon.Live phase on the summary — tap it for the Moon panel: the real lunar surface (NASA’s Lunar Reconnaissance Orbiter map) lit and tilted as it appears tonight, which you can move hour by hour across a month (15 days either side of today) with the scroll bar under it. The scroll bar is a band whose thickness is the Moon’s illumination, with a yellow bar marking now, a dot at each new and full moon to aim for, and a yellow ← NOW button to jump back. Above the Moon: its phase, the date, and where to look — compass bearing, then above (or below) the horizon and by how much. At the top, a perigee-to-apogee distance scale (surface to surface) moves as you scroll. Below: moonrise and moonset with the compass point they happen at, days to the next full and new moon, and a month calendar of phases. All computed on-device for this place.
🧭Find the Moon.On a phone, the Moon panel offers “Find the Moon” at the top: hold the phone flat and aim its top edge like a pointer. Two cards say how far to turn and tilt, a viewfinder shows the Moon against the horizon, and the ring lights up when you’re on it — above or below the horizon. The compass is corrected from magnetic to true north for your location automatically.
☀️Daylight through the year.Tap the “Daylight” line for the daylight band widening toward summer and pinching toward winter — a full year on screen, slidable a year back or ahead, with a yellow ← NOW button to jump back. Dots mark the solstices, rings the equinoxes, dotted lines the clock changes, and a brighter band inside shows the vitamin D hours (Sun above 45°) — a one-line key sits under the chart, and “More” opens the details. The readout gives sunrise and sunset with their compass bearings, day length, the vitamin D window, and the change from the day before; a card beneath shows where the Sun is overhead and how high it climbs at noon here. Sun times are computed on-device, so it works offline for any place.

How the forecast works
🕰️History.Recent past days are the model’s best estimate; days older than ~5 days switch to observation-based reanalysis — what actually happened. (Chance-of-rain stays model-based.)
📐An area, not a pinpoint.Each forecast covers a small area — typically 1–3 km across near towns, larger in remote spots — not one exact address. The yellow circle on the Map marks it.
