What is Calma?

Calma is an iPhone app that blocks distracting apps on a schedule, with daily time limits, open limits and focus sessions. Calma uses Apple's Screen Time, so iOS applies the blocks and they keep working when Calma is closed.

Calma is gentle by design. A blocked app shows Instagram is resting. and one button, Back to calm. Calma has no streaks, no scores and no guilt messages.

Calma needs no account and shows no ads. Calma keeps your rules on your iPhone and cannot see what you do inside other apps.

Who is Calma for, and who is it not for?

Calma fits some people very well and others not at all. Here is when Calma is the right pick, and when another tool is better.

Calma is best for

Adults who tried Screen Time and keep tapping Ignore Limit.
People who want specific times back: work hours, dinner, bedtime, the first hour of the morning.
People put off by harsh or gamified blockers with streaks, scores or paying to unlock.
People who care about privacy: no account, no ads, rules kept on the iPhone.

Calma is not the right pick for

People who want a lock they cannot undo. Calma lets you end a focus session early or switch a routine off. A hard blocker fits better: Brick needs its physical device to unblock, and Opal sells a Hard Mode with Opal Pro.
Android, Mac, iPad or web. Calma runs on iPhone only. Some blockers, such as Opal, also offer Android and Mac apps.
Parental controls. Calma is for your own iPhone and cannot manage a child's phone. Apple's Screen Time parental controls, set up with Family Sharing, are made for that.
Blocking websites. Calma blocks apps, not websites. For websites, use Screen Time's own Content & Privacy Restrictions in Settings.

How does Calma block apps on iPhone?

Calma blocks apps with Apple's Screen Time APIs, the same system behind Screen Time itself. Apple gives app makers three frameworks for this, and Calma uses all three:

Family Controls asks for your permission and opens Apple's app picker. Apple gives Calma private tokens for the apps you pick, not a view of what you do in them.
Device Activity tells iOS when a schedule starts or a daily limit is reached, even when Calma is closed.
Managed Settings applies the block itself, so iOS shows Calma's block screen when you open a resting app.

Because iOS applies the blocks, they keep working when Calma is closed, and your rules stay on the device. More detail: how Calma works and our guide how app blockers work on iPhone.

How do we write our app comparisons?

We make Calma, and we also publish pages that compare Calma with other apps. These are the rules we follow on every one of them:

We say who we are. Every comparison page opens with "We make Calma."
Facts are dated and sourced. Every fact about another app links to a public source at the end of the page, with the date we checked it.
We recheck prices. Prices carry an "as of" date, and we update the page when the App Store or an official pricing page changes.
We say when another app is the better pick. A hard blocker for people who want no way out, or a cross-platform app for Android and Mac.
No invented numbers. No made-up ratings, user counts, awards or testimonials.
Corrections are welcome. Found a mistake? Write to contact@aasntech.com and we will fix it.

What are Calma's design principles?

No streaks, no scores, no guilt. Calma does not count failures or rank you. The only progress number is time protected.
Gentle by design. A blocked app shows a calm screen that names the moment you chose, with one button back to calm. No lecture, no countdown.
Honest exits. A focus session ends early with a 3-second hold. Any routine can be switched off in the app. Scheduled blocks and daily limits offer only Back to calm on the block screen.
Private by default. No account, no ads, and rules that stay on your iPhone.
