A fair comparison for iPhone focus
Opal and StrictBlock both help iPhone users reduce distractions. They are not identical products, so the useful question is which workflow will help you protect the next work, study, or wind-down block.
Opal is designed around broader screen-time management. StrictBlock is designed around deliberate focus sessions, with saved profiles, Pomodoro-style timing, session reflection, and streak accountability.
What to compare before you choose
App-blocker features and pricing change, so verify current details in each App Store listing. Start with the workflow that matters most:
Focus workflow: StrictBlock centers active focus sessions, while Opal offers a broader screen-time management approach.
Blocking options: Confirm how each app handles apps, websites, schedules, and early exits for the version you plan to use.
Accountability: StrictBlock includes focus profiles, a session journal, weekly reports, and streaks for people who want a repeatable session habit.
Choosing the right blocker for your routine
Choose Opal if its screen-time tools and interface fit how you want to manage phone use.
Choose StrictBlock if you want a session-first iPhone blocker with Pomodoro-style focus sessions and built-in accountability. For a feature-by-feature overview, see StrictBlock vs Opal.
FAQ
Does StrictBlock use a VPN to block apps like other tools do?
No. StrictBlock does not use a VPN or network routing. It integrates directly with Apple's native Device Activity and FamilyControls frameworks, which block apps locally at the system level.
Can I use custom block lists in both apps?
Yes, both apps allow you to choose which specific apps and website categories to block, enabling you to build customized focus configurations for study, work, or sleep.
Does StrictBlock support scheduled focus sessions?
Yes. StrictBlock allows you to set up recurring focus windows (such as study hours or evening detoxins) that start automatically, removing the friction of manual setup.
