Yesterday I pointed out a tool for rendering UIViews as image sequences for use within WatchKit. One type of UI component that suits the Apple Watch well is the radial progress chart which apple has used in their example apps, and shown when previewing the Apple Watch.
Here’s an online tool (for which you can also download the source of) that allows you to generate animation sequences for great looking radial charts for use with WatchKit called RadialChartImageGenerator submitted by Hitesh Maidasani.
With RadialChartImageGenerator you can double or triple arcs, customize the colors of each arc, set the minimum/max values of each arc, and place descriptive text in the middle of a single arc radial chart.
Here are a couple of animations from the readme showing the types of radial charts you can generate.


You can use RadialChartImageGenerator on the home page.
You can find the source code repository here.
A nice tool for creating Apple Watch radial charts.
