Mine is originally using Baconreader while in the dorm community bathroom doing a deuce and seeing a mention of Sync. Installed and instantly became a user. Later on I had a problem with the app because I was running beta Android. Reached out to the dev and after a few fix attempts an update was posted that fixed the issue. To get that kind of support is rare and is why I have continued to stand by Sync all these years.
I’ve had it for years, I don’t even know when at this point.
It must have been my most-used app week after week, year after year, phone after phone.
That dev will never see this post, and I’m just one person, but that app made my mundane little life demonstrably better. A little bit better each day.
