Introduction

Built for people who fall asleep to podcasts

SleepCast is a smart podcast player that adapts in real time while you fall asleep, wake up, and continue listening. It combines adaptive sleep timer logic, motion-aware playback, AI summaries, bookmarks, statistics, and practical queue automation into one flow.

I built this app because I fall asleep listening to podcasts, and I wanted a flow that adapts to me instead of forcing me to manage it.

I set a 7-minute sleep timer. After 6 minutes, motion detection turns on; if I'm still awake, I just move a little and the timer automatically extends by another 7 minutes. When I'm drifting off and the timer ends, the app fades into a calming soundscape for 5 minutes. If I move again, the podcast resumes and the 7-minute timer is extended. If I've truly fallen asleep, the soundscape stops after those 5 minutes and motion detection turns off, so the podcast won't suddenly start playing when I roll over in my sleep.

If I wake up during the night, I simply press play on my headphones. The app reads out the current time and a short recap of the last 2 minutes, then continues the episode with the sleep timer reset to 7 minutes.

And when I hear something worth saving, I quickly press volume up and back down: the app creates a bookmark, captures a 1-minute audio clip, and generates a transcript, so I can review or listen to it in the morning.

Later, I can check listening and sleep timer statistics, adjust the app theme palette, fine-tune my inbox and notification behavior, and keep improving the flow instead of starting over each night.

Feature Guide

Complete support overview

Discovery & Subscriptions

  • Search podcasts and open chart-based discovery by country, so you can find relevant shows for your language/region faster.
  • Browse top podcasts and top episodes to discover both long-term favorites and currently trending single episodes.
  • Import/export OPML subscription lists when migrating from another podcast app or creating a backup of your library.
  • Add manual feed URLs for podcasts that do not appear in search but do provide a valid RSS feed.
  • Manage and remove subscriptions to keep your inbox focused on podcasts you currently listen to.
  • Use the inbox as a latest-episodes view that can be refreshed, cleaned up, and sent straight to the queue.

Sleep Timer & Wake Flow

  • Choose a countdown timer or stop playback automatically at the end of the current episode.
  • Auto-restart on play lets you resume quickly when you wake up and want the timer armed again immediately.
  • Fade-out, sleep window, beep volume, and motion sensitivity controls let you tune the behavior to your routine.
  • Extended motion monitoring and optional soundscapes help bridge the gap between falling asleep and waking up again.
  • Resume announcements can speak the current time and a short recap before playback continues.

Player & Queue

  • Playlist mode and binge mode let you switch between mixed listening and one-show-at-a-time listening sessions.
  • Queue sorting options and quick swipe actions help you reorder, summarize, download, or clean up episodes in seconds.
  • Chapter list navigation jumps directly to structured timestamps when chapter metadata exists in the episode feed.
  • Skip interval customization and playback speed control let you match pacing to your routine, from focus listening to bedtime.
  • Mark unplayed, move to top, or remove from queue so your next-up list always reflects what you want to hear now.

Bookmarks, Fragments, Sharing

  • Create bookmarks while listening to capture exact moments without interrupting playback.
  • Optional automatic audio fragment capture stores a short clip around the bookmark for quick replay later.
  • Choose bookmark rewind and fragment duration so clips match the way you save memorable moments.
  • Automatic bookmark fragment transcription adds searchable text to saved moments.
  • Volume-up/down gesture bookmarking workflow gives you a fast hardware-button shortcut when the screen is locked or out of reach.
  • Review bookmark details and replay saved moments to revisit tips, quotes, or key points the next morning.
  • Export/share saved moments as needed when you want to keep or send clips outside your regular queue flow.

Downloads, Notifications, CarPlay

  • Episode downloads with Wi-Fi-only option help you keep episodes available offline while controlling mobile data use.
  • Downloaded episodes list and cache cleanup make it easy to free storage and keep only what you still need.
  • New-episode notification controls, permission status, and indicator toggles let you decide how visible alerts should be in-app and at system level.
  • Hourly checks, last-check feedback, and an in-app test check help you verify that new episode monitoring is working.
  • CarPlay tabs for now playing, queue, and podcasts provide safer in-car control with minimal phone interaction.

Statistics & Progress

  • Open listening statistics from the player to review trends across sessions.
  • See your habits by period, including time spent listening, time-of-day patterns, and top podcasts or categories.
  • Open sleep timer statistics separately from settings to review timer-related behavior without mixing it into general listening data.
  • Replay the statistics tutorial whenever you want a refresher on the charts.

Experimental Audio Tools

  • Speed-sensitive volume for cycling/driving modes dynamically adapts loudness when ambient noise rises with speed.
  • Custom min/max volume bands by speed zone let you tune comfort and audibility for your own commute profile.
  • Sudden sound suppression with adjustable thresholds reduces harsh spikes and keeps nighttime listening gentler.

Settings Overview

  • Language, appearance mode, and theme palette options let you localize the app and personalize its visual style.
  • Tutorial replay, AI help, and statistics tutorial screens help new users onboard quickly and let advanced users revisit complex workflows.
  • Sleep, bookmarks, player, downloads, inbox, podcasts, AI, and notifications are grouped so you can tune each workflow in one place.
