AstroClocks(圖1)-速報App

The AstroClocks Android app collects the simulation of some of the most famous astronomical clocks in Europe.

The first of these is the Torrazzo clock in Cremona, presented both in the current modern version and in the original version, before the reconstruction.

Then the Brescia and Praga ones follow. This last one is also presented in a completely recomputed version that is so shown for the actual latitude as measured by the device.

Individual clocks are accessed via the home page.

The selected clock opens in continuous mode, i.e. the date is the current one and the time is updated every second.

The top right menu allows you to change the operation in the following ways:

AstroClocks(圖4)-速報App

- reset: reset current date and time and proceed with continuous updating of the time

- stop: stop any automatic modification of the current time and date

AstroClocks(圖5)-速報App

- increment date: simulate a date variation in 1-day steps

- increment time: simulate a time variation in 5 minutes steps

AstroClocks(圖6)-速報App

- set hour and date: set the desired date and time

Hand positions are calculated using the most precise methods described by Jean Meeus in the book "Astronomical algorithms".

I have to thank my gnomonist friend Luigi Ghia for giving me the drawings of the moving parts of some of the watches represented here, as well as for encouraging me to proceed with the development of this app.
