Good news for all people who want a good, simple and featured rich task manager. The best part, it's free and works perfectly between mac, PC and ios.
I'm not exclusive Mac user as I work with windows too so I need a cross platform task manager and you get much more features than reminders, like attaching files, sub task,...among others.Why not just use Reminders? It's on all of your iOS and macOS devices by default and you can access it in web mode too.
Microsoft bought Wunderlist and this is their rollout of their modification of it on Macs. So if you liked that (I did), then this. Plus cross platform.
