There’s also Zwallet - which can sync the entire ZECpages wallet on a Nokia Android CrapPhone ™ in just 2 minutes 58 seconds (all 2400 txns & 1600 notes).

It also supports viewkeys, multiple accounts, auto-shielding, displays notes, history, lots of features.

We’ve been testing it here :- Zwallet & Ywallet Testing

You can install from PlayStore here :- https://play.google.com/store/apps/details?id=me.hanh.zwallet

You can get code to build it from here :- GitHub - hhanh00/zwallet

I’m not the developer, I’m just a volunteer helping to test it.

If you have an Android phone please try it & post your feedback. Its insanely fast, has a nice UI & worth your time to check it out.

EDIT: Updated sync time for Version 1.0.8-2059


Big week! That Committee hearing is pretty interesting. Also I have a fax machine now (Jerry Brito quotes that wrong-about-the internet quote, its also wrong-about-fax-machines) and am ready to join the future! Fun fact: the fax machine was first patented in 1843. Sadly, however, the patent was stolen from the inventor and he died penniless because it was so incredibly advanced that nobody really had a use for it so he basically abandoned it. It didn’t take long for people’s interest to change but by then it was too late :printer: and it revolutionized the way information was sent.
Welcome Jessica! :wave:
