If you're not going to update this app can I at least tag people without a subscription

I gave up, for now, and switched to Boost. I really, really love Sync. It's been my favourite app for years. I understand life takes priority, but so does mine to me.

It seems dead. You'd better find something else.

I've given up and switched to Voyager. It's feature rich, but I do miss the performance, UI & UX of Sync.
