### 4/5 — Editing book covers

*2026-09-01*

I’m loving this app so far, but would love to edit the covers

**Developer response:** The latest version of the app now supports editing covers and files.
Thanks for the suggestion!

### 5/5 — Ticks all the boxes

*2026-08-16*

this app does it all. I especially enjoy the equalizer, it is so nice to be able to roll some treble off of the narrator‘s voice at night time to make it sound a little more muffled into my ears. This app is a keeper, give it a try.

**Developer response:** Glad to hear you’re enjoying the equalizer! Thanks for the review, Happy listening!

### 5/5 — I can get through a book so much faster!

*2026-07-28*

The feature that lets me trim out the long silences reduces the listening time by so much! I saved almost 2.5 hours using the balanced mode!

**Developer response:** Glad to hear you like the app! Hope you keep saving yourself time. Happy Listening!
