Ripple
Most Android phones can split the screen or open an app in a floating window, and video apps keep playing in picture-in-picture when you leave them. At work a spreadsheet fills the screen while a show plays in the corner. While studying, an online course takes half the screen and short videos take the other half. Many blockers only check the app in front, so a video in a small window slips through. Kids learn this quickly: homework on top, videos below, and a parent walking past sees only the homework. Ripple for Android v0.1.8 closes that gap. The first part below is for adults setting limits on their own phone, and the second part is for parents. Both Android and iPhone are covered.

From Android v0.1.8, when an app is blocked by a focus schedule, quick focus or a used up daily limit, Ripple also blocks it in split screen, a floating window or picture-in-picture.
If a video app has one hour a day, the minutes watched in split screen and floating windows come out of that hour too.
Before writing a report or studying, tap quick focus on the home screen and pick 45 or 90 minutes or a custom length. By default only the apps in your focus list stay open, so add the documents and chat apps you need for work.
The system phone, alarm and calendar apps are never blocked in split screen, so the calendar stays put during a meeting.
Ending focus early or adding time needs a cooldown, 15 minutes by default, or the unlock code. A family member or friend can hold the code.
The iPhone version is v0.1.5. Put video and social apps into a work or study schedule, and on iOS 16 and later the system blocks them in the background. Split screen blocking and quick focus are Android only for now.
When a child puts a homework app and a video app in split screen, the blocked side gets the block screen, split screen closes, and the phone goes back to the home screen. The homework app is not touched.
If a child shrinks a stream or cartoon into picture-in-picture during an online class, Android v0.1.8 closes it for blocked apps. Add the class app to the focus list so lessons keep working.
Some phones can open a game in a floating window. A blocked game is blocked there as well, and the time played counts toward the daily limit.
Tap quick focus for 60 minutes on your child's Android phone and keep only study apps and the phone app. It ends by itself. For a fixed homework time, create a focus schedule.
The parent keeps the unlock code, turns on uninstall protection and can add strict mode. Android timing uses device uptime, so moving the clock forward does not end anything early. See the clock change page.
If your child uses an iPhone, block videos and games during homework and bedtime. With the block on deleting apps turned on, long press removal does not work. See the iPhone page.
On Android install the latest APK and turn on the accessibility service. If you have an older version, update to v0.1.8 from Settings › About › Check for updates. On iPhone you need iOS 16 or later and Screen Time permission.
Put short video, live stream and game apps into daily limits or focus schedules, and put study and work apps in the focus list.
Split screen, floating window and picture-in-picture blocking is on by default in v0.1.8. Whenever an app is blocked, it is blocked in those windows too.
Put video and game apps into work, homework or bedtime schedules.
For your own phone give the code to family. On a child's phone keep it yourself. Turn on Anti-Uninstall on Android and the block on deleting apps on iPhone.
