🕐 Complications

Forecast Bar offers 27 complications for your watch face, from a simple temperature readout to a rich 5-hour timeline with rain bars. They come in the four standard watch face slot shapes: Circular (small round), Corner (curved into a corner), Inline (the text line above the time), and Rectangular (the large panel).

Complications use the same weather data as the watch app, so they require the same Silver or Gold subscription — and two of them (AQI and Tides) need Gold. See Plans & Subscriptions.

Adding a complication to a watch face

1. Long-press your watch face, then tap Edit.
2. Swipe to the Complications screen and tap the slot you want to fill.
3. Scroll to Forecast Bar and pick a complication from the list.
4. Press the Digital Crown to save, then tap the face to activate it.

You can configure complications on the watch itself — open Forecast Bar on the watch, scroll to the bottom and tap Settings — or from your iPhone under Settings → Watch. Both edit the same settings, and each choice previews what it produces before you commit to it (see Configuring on the watch and Configuring from your iPhone below).

After the update, add your complications back once

If your Forecast Bar complications disappeared from your watch faces after an update, nothing is broken and nothing is lost. The watch app is now built as a single target, which is the modern way Apple wants watch apps put together — and Apple treats the rebuilt app as a new one, so complications placed by the old build no longer have anything to point at. They need adding back once, and only once.

Forecast Bar walks you through it from both ends. On the watch, the main screen shows an Add your complications back card with the steps, and a Done button if you would rather dismiss it. On the iPhone, once your watch reports the loss, a one-line banner appears on the home screen that opens the Apple Watch screen with the same three steps. Both clear themselves the moment your watch sees a Forecast Bar complication again.

The steps are the ordinary ones under Adding a complication to a watch face above: touch and hold the face, tap Edit, swipe to Complications, tap a slot, and choose Forecast Bar.

Temperature and Feels Like

Six variations on the current temperature. In a Circular slot, Temperature renders as a gauge with the current reading in the center and today's low and high at the ends, colored by temperature.

Data point complications

One complication per data point. In Circular slots most render as a small gauge; Corner slots pair the value with a curved arc (for example, Humidity runs 0–100 between a cactus and a droplet, and AQI uses the six-color air quality scale); Inline slots read like "Temp 72°".

Without Gold, the AQI complication shows a small locked placeholder instead of data.

Trio

Trio fills a rectangular slot with three big gauges side by side, each one a data point you pick, above an optional header. It's the one to reach for when you want three readings at a glance rather than a timeline.

When you add Trio to a face, the complication picker lists several ready-made combinations plus Custom · follows Settings — pick that one and the gauges follow whatever you set under Trio in Forecast Bar's settings, on the watch or the phone, without editing the face again.

Each of the three slots can show Temperature, Feels Like, Humidity, Wind, Wind Gusts, UV Index, Precip Chance, Pressure, Dew Point, Cloud Cover, Visibility, Heat Index, Wind Chill, Sunrise, Sunset, Air Quality (Gold), Tides (Gold), or Smart. The header above them is your choice of the location with its conditions icon, the current condition, today's high and low, or nothing at all.

Smart slots

Set a slot to Smart and Forecast Bar fills it with whatever matters most right now, changing it through the day. Smart slots also avoid repeating themselves: each one picks a gauge from a kind the row isn't already showing, so a hot afternoon reads Temperature, Sunset and Dew Point rather than three different ways of saying the temperature. A gauge you pinned yourself claims its kind too, so a Trio you built around Feels Like never gets a second temperature gauge beside it.

Without Gold, the Air Quality and Tides gauges draw a small lock instead of a reading, and a Smart slot skips them.

Sunrise & Sunset

A sunrise and sunset complication built to be read at arm's length: the time in large rounded digits with AM/PM on its own line, in gold for sunrise and rose for sunset. It fits Circular, Corner, Inline and Rectangular slots — inline reads like "☀︎ Sunset 7:41 PM", and the rectangular version pairs both with a live countdown ("Sunset in 2 hr, 14 min").

The complication picker offers it three ways:

• Next Sunrise or Sunset — flips the moment each event passes, with a ring that fills as the day (or the night) runs down.
• Sunrise — always the next sunrise.
• Sunset — always the next sunset.

Only the Next mode draws a ring, because only it has progress to show. The fixed Sunrise and Sunset modes give the space back to the time itself.

Rich rectangular complications

The most powerful complications use the large rectangular slot, and each has its own customizer on the watch and on the iPhone.

The Smart complication earns its name: during precipitation, affected hours swap their icon and temperature for a mini rain chart; late in the evening (at an hour you choose) the last columns become day columns so you're looking at tomorrow instead of overnight hours; and in the very early morning it shows the 5-day layout.

Faces that tint their complications

Some watch faces recolour everything on them to a single tint. From 11.7 Forecast Bar's complications go along with that rather than fighting it: on a tinted face they are drawn in the face's own two tones, so they match everything else you've put there.

Colour can't carry meaning on a tinted face, so brightness does instead. A gauge becomes a bright arc over a faint track, and the marker is set off from both by a dark gap rather than an outline, which on a tinted face would paint solid and disappear. The low and high values stay clear of the ring's ends. A tinted face ends up as readable as a full-colour one — it just reads by contrast instead of by hue.

Configuring on the watch

Open Forecast Bar on the watch, scroll to the bottom of the main screen and tap Settings. The screen is in four parts:

• Watch App — Layout & Data Points, which sets the main screen's header style, which sections appear and in what order, which data tiles show, how the hourly strip is drawn and whether alerts show. See The Watch App.
• Complications — a row each for Trio, Smart Weather, Data Point Graph, 5 Day Forecast and Modular Custom, each opening the same options the iPhone offers.
• Units — temperature and wind units, shared with Forecast Bar on your iPhone.
• iPhone — the sync status, and Sign Out when you're signed in.

Every choice here is drawn as the thing it changes rather than described in words: the Trio presets are cards rendered with the real gauges, each gauge picker is a grid of every gauge drawn for real, and the other pickers show the exact piece they affect — the title row, an hourly column, the graph, a Modular line, an app tile. The full preview stays pinned above the picker and updates as you tap, so you can compare two choices in place.

Configuring from your iPhone

The same options live in the Forecast Bar iPhone app under Settings → Watch. Pick a complication from the gallery there to open its customizer — a live preview updates as you change options, drawn the same way as on the watch. When you're done, sync your changes to the watch (see Syncing your changes below).

Smart

Opened from the Smart Weather entry in Settings → Watch.

5 Day Forecast

Data Point Graph

The chart plots now plus the next four hours as a smooth line with dot markers, colored to suit the data point (blue for dew point and precip chance, green for UV and wind, and so on).

Custom

Compose your own three-row complication. A live preview at the top of the customizer shows exactly what you'll get.

Each of the three rows can show any of these 18 options: Current Temp and Condition, Cloud Cover, Dew Point, Feels Like, Heat Index, High/Low, Humidity, Next Calendar Event, Pressure, Smart Summary, Sunrise/Sunset, Temperature, Tides, UV Index, Visibility, Wind Chill, Wind Gusts, Wind Speed. Rows render like "Clouds: 40%", "H: 85° L: 67°", or "↑6:54AM ↓7:52PM". A Tides row simply stays empty at locations without tide data.

Syncing your changes

There is nothing to press. Change an option on either device and it travels to the other on its own — the phone sends over two channels at once, so a change lands immediately when the watch app is open and is waiting for it when it isn't, and the watch publishes its own edits back the same way. Neither side echoes the other's change back at it.

The iPhone row at the bottom of the watch's Settings screen says where things stand: iPhone connected · changes sync automatically, or Saved on this watch · syncs when your iPhone connects when the pair is out of range.

Occasionally iOS reports that Forecast Bar isn't installed on the watch when it plainly is. Forecast Bar no longer takes that at face value: the Apple Watch screen on the iPhone says what iOS is reporting instead of claiming the app is missing, and your watch fetches the settings itself the next time you open Forecast Bar on it.

Updates and stale data

Complications refresh in the background about every 30 minutes. If the watch can't get fresh data for an extended stretch — beyond about 3 hours — complications show -- instead of an outdated reading. Opening the watch app (or tapping Refresh at the bottom of it) fetches fresh data and reloads your complications.
