Vimcal

We initially loved the idea of Vimcal, as they are trying to portray themselves as the "Superhuman of calendar"—and we love Superhuman.

The thing is, they missed the mark on what actually makes Superhuman special in our eyes.

Vimcal confuses "productivity" with having keyboard shortcuts for everything (talking every single UI component).

This is at the cost of simplicity, making Vimcal feel quite a bit more overwhelming and over-engineered than it needs to be.

And when you're dealing with the monthly cost, we've found that Motion has a far superior scheduler and calendar (all for a similar monthly price), which even includes a time-blocking task/project management for individuals and teams.

Vimcal does have a nice mobile iOS app, although Cron takes the cake in that area (iOS only for both). Motion on the other hand has both an iOS and Android app.
