I used this app when it was in 2.x, and I must say I liked it quite a bit. Mostly the UI, I guess. The functionality and under-the-hood conditions were less enjoyable, and the dev would prioritize whatever sold copies (at least on paper?…), rather than fixing core issues with app's performance. Version 3 was a chance to remedy a lot of such things, but instead, after I'd say pretty short beta period (and I believe just 2-3 beta releases before final) - the app was released, and now it's subscription (liked the release notes pretty much saying - "well, you guys probably expected that, right?"). And the core performance issues still not fixed. And there's STILL not ETA (the tickets for that were up for 2 years).
So I thought… well, I just vote with my wallet and NOT support this dev anymore.
That said, in a quest for a replacement, I found a really nice app which is mentioned below - called Fork. The UI is a bit less polished, but it still is good in its own way. The app is very performant (no need to wait for seconds OR MINUTES for Tower to update my larger repos status), is very easy to use and seems to be made by someone who actually knows how write good software that's good not only on the surface and it pretty much is all I need.
What's more, it's free. But I'd happily pay. Not subscription happily, but a good "standard" dev tools price.
Bad move, fournova…
