What does Skerrick actually block?
Nothing outright. It rations the whole app you pick, not one screen inside it. You get three minutes in Instagram per visit by default, and the clock runs whenever Instagram is in front, whether that is Reels, Stories or your DMs. Limiting the app is how it limits Reels, Shorts and For You. The app is never blocked or deleted, so a message still gets answered, inside the same minutes.
Why can't it ration just Reels, and leave my DMs alone?
Because it cannot see which screen you are on. On iPhone, Shortcuts only tells it when an app opens and closes. On Android it only knows which app is in front. Seeing more would take accessibility access, which lets an app read everything on your screen, and Skerrick does not ask for it. So the ration covers the whole app.
How long do I get?
Three minutes in the app per visit by default, and you can change that. The clock runs whenever the app is in front, whichever screen you are on. When the ration runs out, Skerrick calls time: on Android the cut-off lands over the app where you are, and on iPhone a notification tells you. It refills after thirty minutes away from the app.
What happens when the time runs out?
A full-screen card says 'Not a skerrick left', with the countdown at zero. On Android it lands over the app, mid-scroll. On iPhone, which does not let one app close another, a notification says it instead. Tap it and the card comes up, and if you open the app again with nothing left, Skerrick comes to the front on the card. From the card you can put it down (on Android that takes you back to the home screen), or ask for sixty more seconds and wait out the delay first.
Can I override it?
Yes, and that is deliberate. You can always ask for sixty more seconds. The catch is that each push-through that day makes the next wait longer: five seconds, then twenty, then forty-five, then ninety. The count starts again at midnight, but if you have been pushing through twice a day or more over the past few days, the ladder starts further up rather than back at five seconds.
Why let me override it at all?
Because a lock you cannot open is a lock you delete. Published research on this kind of friction found the dismiss option did more work than the delay itself. People need the door to open. They just need it to be annoying.
How is this different from Screen Time or Digital Wellbeing?
Both ask you at the door, before you have opened anything, and both leave your own limit a tap or two from off. Screen Time on iPhone offers a button that ignores it for the rest of the day, and Digital Wellbeing on Android links its pause screen straight to the switch that turns the timer off. While you have time left, Skerrick does not ask at the door. It lets you in, then calls time mid-scroll, which is the moment you actually want to stop.
Do I need an account?
No. Using Skerrick needs no sign-up, no email and no login, and what you scroll is counted on the phone and stays there. The one thing that signs in is backup, which is off until you turn it on in the You tab. Turning it on signs in with Apple on iPhone or a Google account on Android, so your settings can follow you to a new phone on the same platform: a backup made on an iPhone comes back on an iPhone, and one made on Android comes back on Android.
Which apps can I ration?
On iPhone, Instagram, TikTok, YouTube, Facebook, X, Snapchat, Reddit, Threads and Pinterest. On Android, any app on the phone. The free tier rations one of them, and Pro rations as many as you like.
Which platforms is it on?
Android, on Google Play. The iPhone app is still being built, so for iPhone the buttons on this site join a waitlist, and you will get one email on the day it reaches the App Store.
