Description

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:
- 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
- increment date: simulate a date variation in 1-day steps
- increment time: simulate a time variation in 5 minutes steps
- 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.

★★★★☆ Stanley Williamson · Oct 11, 2020

Great app. These would make wonderful widgets; please consider this for a future update. 👍

★★★★★ donnie spiller · Jun 19, 2025

Very interesting array of Astrao clocks. I just wish it had 12 hour setting instead of 24 hours. It would also be nice if there were instructions on how to read the clock. Talking clock would be nice also. All in all, the app is still highly recommended.
