Alternative to Structured

I have been using Structured since the time it became popular enough... you can say, since its early days. I have purchased the premium version as well. But over the years, although it seems to work well enough, I have been disappointed on its updates... especially about the integration with other OSes.

I have a macbook, and I use Samsung, so android on my phone. It's been almost a year since Structured released their Android version and I was happy about it.

But one thing keeps bugging me, there still hasn't been a sync functionality implemented; in simpler terms, if I add a task on my macbook, it'll not reflect on my phone and vice verse. They even introduced Structured Cloud... sounded promising, yet I can't find a good enough use case unless there's a cross-platform sync functionality.

Another thing that would be really nice to have is to automatically add the scheduled tasks onto my Calendar.

With that said, are there any other apps that works like Structured with these added functionalities? I prefer the minimalistic approach to UI in Structured.

Thank you for your time.
