A golden spiral
Every quarter turn, the spiral grows by the golden ratio, φ ≈ 1.618.
r = 5 · φ2θ/π
Spiralis for Wear OS
A golden spiral tells the hour
The spiral is the hour hand. It turns 30° an hour, and on the hour it lands exactly on that hour's line. All twelve lines are cut from the same curve, the one behind nautilus shells and sunflower heads.
Free. For Wear OS 5.1 and newer. No ads, no accounts, no tracking.

Make it yours
The watch's settings, to try here first
On the watch, long-press Spiralis and tap Customize. You get these same options. Try them on the watch on this page.
Reading the time
Find the hour line the spiral is lying on, or about to reach. That line glows, and its numeral brightens. The small dial in the middle keeps the minutes; tap it to open your alarms. Drag the slider under the watch, press play to watch a whole turn, or jump to a time:
Presets
The phone app sets up the face in one tap: a palette and a set of complications. Empty slots draw nothing, so the spiral runs through their space. A fresh install starts in Golden, with all four slots empty.
Color
Thirteen Material 3 Expressive palettes, shown the way the watch's editor shows them. Each one colors the spiral, the progress bars and ranges, and the current hour line.
Minutes
Read the minutes on the small center dial, or let the current hour line fill up over the hour, the way the spiral sweeps it. Or both.
Numerals
Show all twelve, only the current hour's, or none for a face of just the spiral and its lines. A hidden numeral leaves no gap in its line. Each one has a thin black outline, so it stays readable where the spiral crosses it.
Hour lines
Keep each line a short piece of the spiral, or let it run on along its own curve: Fading reaches from the center dial out past the rim, fading both ways; Vortex swirls all the way into the center. They're one curve 30° apart, so they never cross. On the center dial, the current hour lights up along its whole line.
24-hour
Each stack of numerals names the next time the spiral reaches it: from 7:00 the top reads 13–18, from 13:00 the bottom reads 19–24, and they switch back at 19:00 and 1:00. Two-digit numerals get wider gaps in their lines. With no numerals, it has nothing to change.
Always-on
A thin spiral and dim lines, lighting only a few percent of the screen. Keep it neutral grey or tint it red, blue or green: each keeps the same brightness. Keep the complications, or hide them for a spiral-only face.
And the rest
Here the rings show the weather and the time, and the arcs your battery and the day's forecast. Swap in any complication you like: rings and arcs fill up for values like steps or battery, and mark a range like today's temperatures.
Straight from the watch
Four presets, thirteen palettes
Captures from a Wear OS 6 watch. Always-on lights only a few percent of the screen and keeps the spiral readable.
How it works
One curve, twelve hours
30° an hour
The spiral turns clockwise once every twelve hours. Each hour line is the spiral itself, frozen where it lies on the hour, so the hand and the line meet exactly.
Something hidden
For one minute every twelve hours, the face has a little something to say about where its curve comes from. You'll know it when you see it.
