Snap ! - the sundial app
Snap! is a web-based app. Select a country then a city to display the current sundial for a city nearby to your location. A red line shows the current clock time at that location, with midnight at the top, and noon at the bottom. (Why are these different). The blue line at the top of the shadow shows sun time (during daylight hours)
This free app shows the lines and shadows projected onto a sundial face designed for 51.5 degrees; a sundial designed for your latitude would have hour lines calculated for that latitude. To build your own sundial, click here
Our subscription app is only $12 a year, gives you many more cities to choose from, and displays much more data including the time of solar noon and the apparent declination of the sun.
We would welcome your comments on our new app.
