Yes, you can build an Opal-style app using Apple's Screen Time tools, with permission and setup.
You can build an iPhone app that blocks selected apps during focus sessions and scheduled hours. Real blocking uses Apple's Screen Time tools, so you need user permission, Apple's entitlement approval for distribution, and testing on an iPhone.
What keeps people on Opal:Years of polish
The checker split your own version of Opal into its key parts and sorted each one.
Choose distracting apps
Use Apple's Family Controls picker so you can select apps after granting Screen Time permission.
Needs setup
Timed focus sessions
Vibecode can build sessions that use Apple's Managed Settings tools to shield selected apps on a real iPhone.
Needs setup
Scheduled blocking
Use Apple's Device Activity tools to start and stop blocking during your chosen hours.
Needs setup
Focus session history
Save completed sessions on your device and show your focus time without reading other apps' private data.
Works out of the box
A native iPhone app can use Apple's Screen Time tools to block selected distractions.
Plan ahead: Request Apple's Family Controls distribution entitlement early, since real blocking needs this approval and cannot be fully tested in the browser simulator.
Written by the checker for a first version. Paste it into Vibecode as is, or change it to make the app yours.
Build an iPhone app for people who want fewer distractions and more focused time. The main screen should show selected distracting apps, a focus duration control, and a large Start Focus button. Let me choose apps from a realistic sample list, then start a countdown with a clear simulated blocking state. Let me end a session and view completed sessions in a simple history screen saved on the device. Use a calm navy and cream design with large text and uncluttered cards. Use realistic sample data and clearly label blocking as a demo until Apple's Screen Time tools are connected.

Vibecode builds a first version from one prompt, and the checker would start with these parts: a sample list of distracting apps you can select; a focus timer with a simulated blocking state; focus session history saved on your device. Plan on a weekend for a working first version with its real features.
Vibecode's first build is free for new accounts that sign up with Google or Apple on the web or the iPhone app, as the account's first project: one build of about 10 minutes with up to 3 features, on sample data. After that you need credits, from a paid plan or auto-reload. For your own version of Opal, the checker lists these costs: Vibecode Plus ($20 a month); Apple Developer Program ($99 a year).
Opal gives people a maintained blocker, friends already using it for accountability, and an established community for advice. A version you build yourself won't have these: friends already using Opal; Opal's established user community; Opal's ongoing fixes and support.
