Back in the day I loved the Dialer for Pebble app: Dialer for Pebble - Pebble Appstore. The companion app is not in the play store anymore 
Is somebody working on an update or alternative?
Matejdro, the developer of that and Notification Center told me he wasn’t updating the Dialer. Too bad. I used both on my old Pebbles
Has he published the source? Maybe somebody can fork it and make it work again?
I have no idea. I pinged him about it via GitHub a few months ago.
