Comparison

Momentum vs Opal

Opal is a focused screen-time blocker. Momentum is a discipline system that includes a screen-time lock tied to your daily score.

If you only want to block apps on a schedule, Opal is built for that. If you want your phone to unlock when you've actually executed, Momentum is.

The core difference

Opal sessions are time-based: block these apps during these hours. Momentum's Earn Your Apps is performance-based: after your cutoff, apps stay locked until your daily score reaches your target.

Momentum also tracks the work itself — sleep, deep work, training, nutrition, content, focus — with an AI coach and weekly reports.
