[PD] chronometer + metronome that syncs multiple Android/iOS devices over network?

hi all

We need a chronometer that runs in sync in multiple devices at the same 
time. Target platform is android, and if possible iOS as well. We are 
thinking also that it would be great to have some sort of metronome 
running together with the chronometer (we have trained musicians 
together with non trained musicians in the ensemble).

So far we have been using http://chronograph.io/ so far but it is not 
100% reliable, we had a few issues last performance (one device was ~1 
sec behind the others, and often during rehearsals we had problems with 
the start signal not being sent at all).

I am considering the possibility of implementing this functionality in 
PD using PDdroidparty and OSC. Because we dont like the tools we have 
found online. We found some nice metronomes but the only one that seems 
to sync is only iOS. And we do need the chronometer (in fact priority n1 
is the chronometer right now). I thought maybe someone can point into 
some existing alternative before I try to reinvent the wheel.

One of the biggest issues I foresee is to find an easy and quick way for 
the master device to find out the available slaves in the network. I 
would not like to have to, one by one, find and then type the IPs of 
each single device in the master device, although the master could be a 
laptop running PD and that would make it easier to type them...

thanks in advance for any feedback
