Short answer: Pick Opal if you want a lifestyle screen-time dashboard on iPhone and Android and will pay ~$99.99/year for Deep Focus. Pick Hardcore Focus if you want timed focus sessions, no account, native Screen Time blocking, and an on-device AI that argues back when you try to unlock early ($3.99/wk, $8.99/mo, or $49.99/yr).

Is Opal or Hardcore Focus stricter?

Opal’s hardest mode is Deep Focus, behind Pro. Hardcore Focus puts the hard part in the session: No Bypass, a 15-minute bypass, or the AI Gatekeeper (15-minute grant ceiling, on-device). Neither app can stop Settings → Screen Time if you revoke permission. Can you bypass iPhone app blockers?

Which is more private?

Hardcore Focus has no account and no backend. Data stays on-device and in your iCloud. Opal is a full product with an account and a broader analytics surface. If “no sign-up” is the requirement, Hardcore Focus wins by construction.

Price

Opal Pro is about $99.99/year. Hardcore Focus annual is $49.99 with a 7-day trial. Hardcore Focus has no free tier — it is a hard paywall. Opal is easier to try at $0 and more expensive if you want the strict mode.

Who should pick which

  • Screen-time scores, Android, a polished dashboard: Opal.
  • This session, this goal, argue with an on-device AI, no account: Hardcore Focus.
