■ "Break, break, always break." gets things moving "Just a quick break"—and 30 minutes are gone. Open a comic, and the rest of the day is over. The harder you say "do it," the more they freeze. PlanetLoopTimer is a visual timer that turns the break itself into your child's "next motivation switch." Launch a planet, orbit the sun—the orbit is the break time. Pulled into the sun, it ends. "I want another shot, and a better one"—that feeling pulls the next small step out of them. ■ Not "5 minutes ticking by," but "you launch your own break" A normal timer starts counting down the second you press the button. For a kid, time is leaving without their say—it just feels unfair. That's why "just a little more!" never stops. In PlanetLoopTimer, the break length is decided by your launch. Eye the angle and power on the guide line, then release at the right moment. Launch well: longer orbit. Miss: much shorter. Because they made the time themselves, the end feels easier to accept too. ■ Planets, around the sun, round and round Each planet has a different break length. The farther from the sun, the longer it orbits. "It's far, so it goes longer"—that's intuitive for kids. As the target time gets closer, the sun's gravity slowly grows, and the planet spirals in. Watching a planet stay in orbit feels nothing like a forced 5-minute countdown. It's a timer, but it plays a bit like a game. That's how "fun breaks" are born. ■ Three easy steps ① Pick a planet The number on each planet on the start screen is the break time guide. ② Look at the guide line, and launch Picture the angle and power, then fire. A clean launch orbits long, a miss falls short— it's a timer, but you'll find yourself wanting to get better. ③ When it's pulled into the sun, the break ends The moment it's swallowed up, "what's next?" rises naturally. ■ Pluto only: ∞ Challenge mode Pluto has no rising-gravity setup. With a clean enough launch, it just keeps orbiting. Use it as a "personal record" treat for your kid. ■ A great fit for these kids and families [For kids who…] · "5 more minutes" stretches on forever · Open a comic or a game and can't put it down · Have a strong sense of their own pace · Move on "I want to try" more than on reasons · Love breaks, but can't quite catch the cue to end one · Have ADHD, ASD, or time blindness traits [For families where…] · "Do it!" has become a daily refrain · You want kids to move because they're convinced, not because they're told · Timers tend to turn into arguments · You'd like a fun mechanism for daily routines "Launch" instead of "scold." Change the word that moves them, and the day gets a little lighter. ■ About ads To avoid disturbing the timer, the main planet modes (Mercury through Neptune) show no ads at all. Ads appear only once, at the end of the Pluto (∞ Challenge) bonus mode. · Regular planet modes are fully ad-free — during and after the timer · One ad only at the end of Pluto ∞ mode · No ads during the timer or while you're operating the screen · We configure AdMob not to receive the advertising identifier (IDFA) · Data stays on your device, never sent externally May your daily breaks become a little space adventure. ■ Sister apps "LastDays" — counts down the time left with your kid, in "how many more times." "TodoGatya" — for slow mornings — kids draw the next task from a gacha and start with a surprise.
