What listeners say

A curated, balanced selection of Apple Podcasts reviews.

Olimpia’s voice is like silk and the subjects she chooses are interesting enough to keep my mind off my own thoughts and get some sleep. In fact, there are some episodes I save for waking hours I’m so interested and enjoy her delivery that much. She reads with understanding, not monotony. I run past the ads and the podcast has turned off mid-episode ads. Waking to ads has never been an issue.

Homesick for Bay Area · Aug 2026

Olympia’s voice is so soothing that I never make it more than three or four minutes. I can sleep again 🫶

Ersy Bearsy · Jul 2026

I love listening to history and science podcasts to fall asleep, but I’m incredibly sensitive so I have to be really picky about soft voices that don’t have too much variation in tone while also being expressive. Olimpia is amazing and gently guides you through some amazing places in the galaxy or stories of forgotten gods. I hope this show goes forever ❤️

Russell0614 · Jun 2026

i’m very picky when it comes to podcasts, particularly the ones i listen to in order to fall asleep. love this one, especially that it’s not ai! ads are just at the front, i fast forward past them. she also does a mini relaxation exercise at the start of each ep right before beginning the narrative. highly suggest!
