Yeah thats how I discovered it as well. At the time, it was the only Lemmy app available on iOS (not sure if there is more now), and I was surprised how well it works. It‘s also open source, and the guy making it seems to have a similar community driven approach in development as Christian has, which is greatly appreciated.
Absolutely! For being just a couple of days old, it’s ridiculously well engineered. I wonder if Christian hops aboard the Lemmy train, and gives a spin at creating his own Lemmy app. This could vastly increase attention to and traffic on Lemmy.
