Opal

Session

Opal

The free plan allows 1 rule and shows the Opal Score for the current day only.
Hard Mode, Allow Only, unlimited rules and score history all require Pro.
No Windows, Linux or web version is listed, and the App Store lists the iOS app for iPhone only.
Opal's Mac page lists app limits and sync with the iPhone app as still to come on Mac.

Session

Apple platforms only: macOS, iOS and iPadOS. No Windows, Android or web version is listed.
The free plan shows analytics for the past 2 days only, and custom session and break lengths need Pro.
Blocking needs Pro, and the pricing page lists website and app blocking as Mac only.
Real-time device sync, Slack muting and Apple Calendar event creation are Pro features.

Opal

Focus Rules: Rules block chosen apps automatically on a schedule, after a time limit or after a set number of opens. The free plan allows 1 rule and Pro removes the cap.
Focus Timer: Pick what to work on, set a duration and stay locked in until the timer runs out. Advanced timers and soundscapes are part of Pro.
Hard Mode: A Pro setting under which Opal cannot be turned off while a block is active.
Opal Score: A single daily score built from sleep, focus and rest signals. Free accounts see today's score; the history needs Pro.
Mac app: Sessions block distracting websites and apps on macOS 13 or later, with the same Normal, Timeout and Deep Focus levels as the iOS app.
Opal for Schools: A separate school program in which administrators block set apps during school hours and follow usage on a dashboard.

Session

Pomodoro sessions: Work in 25-minute sessions separated by breaks. Setting your own session and break lengths needs Pro.
Focus analytics by category: Tracks how long you focus on each category, such as writing, coding or a client. Free shows the past 2 days and Pro opens the full session log.
App and website blocking on Mac: Pro blocks the apps and websites you choose while a session runs. Website blocking works in Safari, Chrome, Brave and Microsoft Edge.
Calendar events: Every plan shows your calendar events inside Session. Pro can also create an Apple Calendar event automatically when a session finishes.
Slack status: Pro updates your Slack status when the timer starts and restores it when the timer ends.
Device sync and automation: Pro syncs in real time, so a session started on a Mac can be ended on iOS, and adds automation through AppleScript on macOS and Apple Shortcuts on iOS.
