I just updated to the Beta and tried it out for about 30 minutes.

The reflections is quite nice because of it’s probing nature. And if you just want to dump in your thoughts it will be good as well and you can add the auto generated memories from photos in there if you want.

But I suspect that the other two apps that you used will have much more functionality than this currently. I used Diaro and it has many features in there that I would still want the journal app to add.
