Opal is a polished iOS screen time app, but the full experience costs about $99.99 a year. Lock In gives you real blocking, stats, and streaks for free on iOS and Android. Here is how they compare.

If you are on iOS and happy to pay around $100 a year, Opal is genuinely well made. But if you want real blocking without a subscription, on both iOS and Android, Lock In does the core job for free, adds a whitelist Opal lacks, and lets you lock in with friends.
