FAQ

What devices does WabiFace Sumi work on?

WabiFace Sumi requires Wear OS 5 or later. Compatible with Pixel Watch 2/3/4, Galaxy Watch 6/7/Ultra, and other Wear OS 5+ smartwatches. Earlier devices running Wear OS 4 or below — and Apple Watch — are not supported.

How much does it cost?

During the limited sale, Sumi is $0.99 on Google Play (regular price $1.99, set by Google Play; the price shown on Google Play is authoritative). One-time purchase. No subscription. No ads. The sale ends June 12.

How does the calligraphy change through the day?

Each weekday has its own kanji. Starting at midnight, one brush stroke is added at the top of every hour, so the character is gradually completed across the day. The newest stroke glows vermillion before fading to ink. Three ink themes are included.

Can I get a refund?

Yes — Google Play offers a 2-hour refund window for any app purchase. After that, please contact us at support@wabiface.jp.

Is the animation always running? Will it drain the battery?

Animations only run in active mode. When the watch enters always-on (Ambient) display, a dimmed monochrome version is shown to preserve OLED battery life.
