How to run the latest Reminders app on OSX Mojave or alternative ToDo apps?

Like many i can't move my primary Mac to Catalina until an option becomes available for me to run 32bit apps. Something even Apple could provide in the form of an emulator or i buy Parallels, ...

Unfortunately my phones and ipads are all using the latest version of Reminders and i can't access them with Mojave's version of Reminders.

Does anyone know if there is/will-be an option to run the latest Reminders app on Mojaves?

Alternatively, are there any other options that people would recommend (nb. don't need to be Apple)?
