Having a little anxiety here because this is by far the best app. I purchased a lifetime Ultra membership and it wasn’t until I replaced my phone and couldn’t restore it, did I find out the developer hasn’t updated or posted in 2 years. (Somehow the Ultra got restored a couple days later).
I really hope the dev continued this, or issues a statement regarding the status. I also would pay for a version for Reddit (yeah I know, I just can’t quit that completely yet)
Edit: thanks for the responses. So far, Voyager seems to be the closest to Sync and best alternative for me. Really sucks the dev just abandon this.
Another vote for Summit. It is a little different, of course, but it’s the closest I’ve found. The dev is also super responsive and works on the app actively.
