GrateGuard includes unlimited protected apps, text-based gratitude resets, custom lock hours and session duration, and the latest seven days of local history in its free core. Opal also has a free plan; its official pricing page currently lists one rule, app blocking, basic timers and today’s Opal Score.
Yes. Opal’s official pricing page lists iOS, Android, and Mac, and its Android app is available on Google Play. Features can differ by platform and product version.
Opal lists harder blocking and no-unblock options in Pro. GrateGuard is designed as a personal behavior boundary: it places a gratitude ritual before selected apps, not a tamper-proof parental-control or device-security system.
Choose the loop you want to repeat. Pick GrateGuard when you want a focused gratitude ritual, a no-account setup, and unlimited free app selection. Pick Opal when broader focus rules, timers, soundscapes, reports, and multi-platform support matter more.
