What happened to the URL on file for Sound AiSleep?

URL unreachable The URL on file (https://apps.apple.com/us/app/sound-aisleep/id6473125317) did not respond across three consecutive checks; the streak completed on 2026-09-19.

This reports what that URL did, not a claim that Sound AiSleep itself is gone: the address on file does not confidently match Sound AiSleep's own domain, so if it turns out to be a marketplace or listing page rather than Sound AiSleep's own site, this observation is still accurate about the URL, just not about the product. See the methodology for how the match is made.

The vendor's own description, unedited:
Sound AiSleep is an innovative application designed to offer unique kids bedtime stories narrated in the user's voice. The app works by creating a digital replication of the user's voice through AI technology after a few minutes of voice recording. Users can then select any kids book from the app's library to produce a personalised audiobook narrated in their own tone. This makes the app ideal for lulling young ones to sleep with familiar vocal tones. In addition to this, the app is developed by L&C Partners Ltd, and it comes with its privacy practices that may involve handling of data. Notably, the data used could be linked or unlinked to the user's identity, varying based on features usage and age. The app also offers in-app purchases. It's compatible with iPhone, iPad, and iPod touch and requires iOS 13.4 or later.
