Character
Charms from around the world, grouped by region. The ones near you are free; tap a Pro charm to see it for 30 seconds.
Rope
How far it hangs (short, medium, long or extra long) and its style: classic string, red yarn, gold chain, pearls, rainbow, spider silk, marigold garland or fairy lights. String and yarn are free.
Look
Animation: lively squishes, hops and fidgets; calm is gentler; off just hangs and swings. 3D clay finish for soft light and shade, and a regional glow under each charm.
Weather
Weather falls across your whole screen: seasonal (snow, blossoms, monsoon rain, leaves), with stars at night, or festival days like Diwali, Holi, Eid, Christmas, New Year and Pongal. Choose the amount, and whether it falls over my apps or only on the desktop. Celebrate festivals automatically changes the weather, rope and a greeting for the day. Off and snow are free.
Screenshots are from Windows and Linux. The Mac app has the same settings in its own Settings window.
