I've been using The Five Minute Journal [1] (on paper) for a while (definitely not every day) and it has a gratitude component. I do enjoy how it helps prompt me to change my perspective :)
Can I ask how it prompts to change your perspective? I might want to implement that. It’s not clear to me based on the link you gave. Thanks for sharing!
