Chrobox vs Opal: Which is Better? [2026 Comparison]
Opal is a dedicated screen-time and app-blocking tool with a strict Hard Mode you cannot switch off mid-session, plus a free tier. Chrobox is a timeboxing app first, and blocks the apps you choose only during the time boxes you schedule, with no equivalent to Opal's always-on Hard Mode and no free plan.
Chrobox vs Opal: Which Should You Choose?
Choose Opal if you need blocking so strict it cannot be turned off mid-session, or want to start free. Choose Chrobox if you want blocking to happen automatically as a byproduct of planning your whole day, with tasks, routines, and reflection built in.

Frequently Asked Questions
Common questions about Chrobox vs Opal
Is Chrobox a good alternative to Opal?
Chrobox is a good alternative if what you actually want is a planner that also blocks apps during scheduled work, rather than a dedicated blocker. It is not a substitute for Opal's Hard Mode, which cannot be disabled mid-session and is stricter than anything Chrobox offers, and Chrobox has no free plan while Opal does.
What is the difference between Chrobox and Opal?
Opal is a dedicated screen-time blocker with a free plan and a Hard Mode that cannot be switched off once started. Chrobox is a timeboxing planner where app blocking is tied to the time boxes you schedule for tasks and routines, and runs alongside task planning, routines, and AI analysis, but is Pro-only.
Does Chrobox have a Hard Mode like Opal?
No. Chrobox blocks the apps you choose only for the duration of a scheduled time box, using Apple's Screen Time API on iOS or an Accessibility overlay on Android, and there is no always-on mode that resists being switched off mid-session the way Opal's Hard Mode does.
