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.
