A schedule you set in advance, against a day you earn back one task at a time. We make one of these, so every fact below links to where it came from.

The table scrolls sideways when it does not fit.

Who Opal is right for

Opal is the broader tool, and for a lot of people it is the right one. It is the only app in this comparison running on iPhone, Android and Mac, so if the hours go on a laptop as well as a phone it is the practical answer. Its scheduling is the most developed of the apps we looked at, with recurring sessions and a Hard Mode that makes ending one early harder than a tap.

It also has a real free tier, so you can find out whether a schedule is enough for you without paying anything. If it is, stop here. Paid Opal is expensive next to this category, but you would be buying the cross platform coverage, and nothing else here has it.

Their privacy page states that private data stays on your device and that they do not store it. Signing up for an account is described as a choice rather than a requirement. Source: https://opalapp.com/pricing.

Who ScrollBuddy is right for

ScrollBuddy is narrower on purpose. iPhone only, one mechanism, no schedule to design. The apps you picked are shut from midnight, and they open for thirty minutes when you finish one of the one to three tasks you wrote for the day.

That suits a specific problem: not high hours in general, but a morning that goes missing and a list that never gets started. A schedule cannot help with that, because the hour you block is not the hour the day goes wrong. If your problem is the hours themselves, or if your desk is where it happens, Opal fits better.

No account and no login. Blocking runs on Apple’s Screen Time permission, so ScrollBuddy never sees which apps you open. Your first full day is free. After that it costs money, and if it does not help you can walk away free.

The honest caveat

Neither app can stop you. You can turn it off. ScrollBuddy holds no key you cannot take back, and it only ever knows what you tell it. Opal’s own pricing page and its App Store in-app purchase list do not agree on the tiers, so treat any price you read anywhere, including here, as something to check on the day you buy. All six apps in one table are at screen time apps compared.
