* Data as of May 27, 2026. Competitor details reflect the latest public releases on iOS: Apple Podcasts (iOS 19.x), Spotify (v8.9.x), Pocket Casts (v7.45.x), and Overcast (v2026.x). Popovers outline specific feature configurations.

Dyslexia, Color Blindness, & Low Vision

Visual accessibility is often treated as an afterthought in mainstream apps, which rely on system-wide font scaling that distorts layouts, or default to low-contrast color palettes. CastKeeper builds tailored reading tools and color-blindness accommodations directly into the playback and discovery experience.

High Contrast Mode

Text, borders, and controls adapt automatically to stand out clearly for users with low vision or reading fatigue.

Monochrome Mode

Offers a grayscale display option to accommodate color blindness and reduce visual cognitive load, providing a clean, non-distracting reading experience.

Dyslexic Support

Native support for the OpenDyslexic font in areas with heavy text content. Toggle a weighted-bottom letter layout designed to increase character recognition and readability for users with dyslexia.

Deafness, Hard of Hearing, & Single-Ear Loss

Audio-first media shouldn't exclude listeners who cannot hear or who have single-ear (unilateral) hearing loss. CastKeeper provides local, hardware-level mono summing so you don't miss vocal details or instruments, and runs private on-device Whisper models to deliver real-time Live Captions with smart sound cue identification.

VoiceOver Support

Descriptive accessibility labels, hints, and traits read out layout details aloud, making navigating features a fluid, audio-guided experience.

Live Captions & Sound ID

Real-time, on-device AI captioning that transcribes audio and video podcasts as they play. Features built-in sound cue identification (detecting laughter, applause, music, and background noises) privately offline with no subscription needed.

Mono Audio

Combines left and right stereo channels into a single mono output, ensuring a complete and rich audio experience for listeners hard of hearing in one ear.

ADHD, Autism, & Sensory Sensitivities

Hyperactive layouts, infinite scroll animations, and uncontrolled phone-wide vibration can trigger vestibular symptoms, motion sickness, or cognitive fatigue. CastKeeper gives you the ability to turn off all interface animations completely and dynamically customize mechanical haptic feedback.

Remove Animations

Removes animations in the interface for those with sensory sensitivities. When enabled, non-essential transitions, zoom effects, and UI motion are disabled to prevent sensory strain.

Haptic Intensity

Supports adjustable vibration feedback via the Apple Taptic Engine. Easily tune tactile response levels for navigation gestures and playback controls to match your comfort level.

Privacy

Your Data Stays

CastKeeper never collects your data. Privacy is a right, not a feature. Everything happens on your device, synced through your own accounts.

AI doesn't cost you your privacy.
