Yes, iPhone can block websites. The useful part is making the block easy to live with.
Apple's Screen Time tools can restrict websites, but the raw interface is not designed around quick focus starts or personal weak-hour schedules. Stillpoint helps by wrapping those controls in a calmer app flow.
- Block websites alongside apps and categories in one block list.
- Use manual focus sessions for immediate protection when you feel the drift starting.
- Use weekly schedules if the same browsing spiral happens at the same time every day.
