Better than meds
I also am on the aphantasia spectrum (I am not able to make pictures in my head) so I was afraid this app wouldn't work for me, but it does. I just let the objects appear in whatever senses are available to engage with it. If the word is rose, I feel soft petals against my face as I smell the rose. If the word is river, I hear rushing water and feel it cold against my feet. If the word is earmuffs, I feel them soft against my ears and hear the world muffled. You don't have to be able to visualize the things for this app to work.
