FYI, I recently launched Kalnext, a 12-month planner that connects with Google Calendar.
I had the same need as many of you, and since this project seems abandoned, I decided to build Kalnext myself.
It’s a small paid service (just a few euros a month) so I can keep it sustainable and keep improving it based on feedback.
That said, the first year is free for the first 100 sign-ups.
It’s still a work in progress, but I improve it a little every day!
