Kyukan Lock puts a speed bump between drinking limits and late-night apps
An iPhone app for setting a nightly alcohol limit, logging drinks, and temporarily locking selected apps on rest days or after the limit is exceeded.
- For
- iPhone users trying to moderate nightly drinking
- Worth noticing
- It defines one drink as 10 g of pure alcohol and treats 5 a.m. as the end of the drinking day.
Field notes
The app counts pure alcohol in 10-gram units and treats the day as ending at 5 a.m., so a late-night drink remains part of the previous evening. Its Screen Time controls let users choose which apps to restrict; the homepage says the app itself cannot see those selections. The site also sets a clear boundary: it describes the product as a self-care tool, not a medical device, and directs people with concerns to a doctor or alcohol-reduction clinic.
