A developer has released Punish, an Android app that lets users set screen-time limits and charges them $15 if they exceed them, with the money donated to an organisation of the user's choice, including ones they dislike such as the NRA or Everytown. The idea is that donating to a cause you oppose makes the penalty genuinely motivating rather than a trivial cost.

A developer reports that on October 6, 2026 their app, Nada, received production access on Google Play after going through a paid campaign on PeerPlay. The developer calls it the first app to gain Play Store production access this way and has published a full case study describing the process. The story is being shared among developers interested in alternative routes to app store approval and distribution.

Apple has begun accepting app submissions built for the iPhone Duo, with developers able to send in their software ahead of launch in the hope of being approved in time for day one. Coverage so far is limited to the announcement itself, with AppleInsider noting that approval timing is not guaranteed and developers are essentially racing the clock to be ready when the device ships.

Discussion is focusing on macOS's Full Disk Access, a permission that has worked as a simple all-or-nothing switch for roughly ten years: an app either can read everything on the disk or nothing at all. Commenters argue Apple has effectively acknowledged this binary model was never designed for the granularity modern software needs, and are debating finer-grained alternatives.

Parents are being offered guidance on how artificial intelligence tools should be used around young children, as experts weigh whether the technology is more helpful or harmful for early development. The advice encourages parents to supervise AI use, understand what these tools can and cannot do, and set sensible limits while recognising the growing role AI already plays in apps, toys and learning products aimed at kids.

A developer has laid out the case that a birth chart is a purely deterministic calculation: the same birth time and place always produce the same result, with no data or randomness involved. That makes the job ideal for local computation, and the argument is that a smartphone is a better astrology computer than a remote server, removing latency, cost and privacy concerns.

Submissions for iPhone Duo apps are now open, according to MacStories. The news means developers can begin submitting apps built for the Duo format on iPhone.
