For Android families

Screen time that gives something back.

When the daily limit runs out, kids don't hit a wall. They earn more time by moving, learning and thinking: a quick set of squats, a round of maths, a times table said out loud, a few flashcards. Then back to the game.

The reality

Screens aren't going anywhere. Neither are the arguments.

In this day and age, keeping kids off screens entirely is close to impossible. Homework, friends, games and shows all live on the same device. Every evening turns into a negotiation — "five more minutes", "you said I could", "that's not fair".

Most limit apps simply say no. The screen goes dark, the child feels punished, and the fight starts anyway — just aimed at the phone this time.

A different deal

Not giving up. Not banning. Something in between.

You set the daily allowance. When it runs out, your child can unlock more by completing an activity you've chosen. Every extra block of screen time comes with a built-in break.

Physical

Squats and step goals get them off the sofa — a guaranteed movement break between sessions.

Educational

Maths pitched at their school year, and flashcards on anything from capitals to science words. A few minutes at a time.

Mental

Saying a times table or a flashcard answer out loud builds recall and confidence. No typing, just thinking.

The 10,000-hour rule

They say mastery takes 10,000 hours. We'd like to chip in.

Nobody masters the piano between videos. But five minutes of times tables here, a few flashcards there, twenty squats after lunch: it adds up. Every unlock is a few more minutes on the road to something they're genuinely good at.

How it works

Three steps. Set it once.

  1. 1

    You set the rules

    Create your parent PIN, choose which apps count, set a daily limit, and pick the challenges your child can use to earn more time.

  2. 2

    They play as normal

    Your child uses their apps as usual and gets a friendly heads-up before time is up — no surprise cut-offs.

  3. 3

    Time's up? Earn more

    A playful lock screen offers challenges. Complete one, unlock more time. Your parent PIN can always override.

The challenges

Quick, fun, and actually good for them.

Each one takes a few minutes. Short enough to feel fair, long enough to matter.

Educational

Math quiz

Ten questions pitched at your child's school year, from the topics you pick: addition, subtraction, multiplication, division and fractions. It gets harder as they get better, and brings back the ones they found tricky.

Answers go in on a big number pad, with a rough-work pad for working things out.

Times-table recitation

Kids say the table out loud ("three times four is twelve") and the app listens and follows along. Pick a range of tables up to 20, and each unlock asks up to 5 of them, a different one each time. Hide the answers once they're confident.

Flashcards

Twelve ready-made topics, from country capitals and flags to space, science words and the human body. Or write your own cards for this week's spellings.

Your child flips through 20 cards, then answers five of them by typing, picking from four options, or saying it out loud. Cards they miss come back until they stick.

Physical

Get up and walk

Set a step goal and the screen stays paused until they've walked it. Steps are counted by Health Connect or the device's own step sensor. A lap of the garden or a trip up and down the stairs is enough to break up a long session.

Squats, counted by the camera

On-device pose detection counts each squat as it happens, and only proper ones count. No video is saved or uploaded.

Educational

Follows their school year

Tell the app your child's school year in the UK, India (CBSE) or the US, and the maths and the ready-made flashcards are pitched to match.

Coming soon

On the way

Verses, prayers and passages

A recitation library with Bible verses, surahs from the Quran, Sanskrit shlokas, Gurbani, Buddhist and Jewish texts, plus poems and famous speeches. Let the app pick a few at random from your selection, or choose exactly which ones come up.

Record your own. Say a family prayer or a favourite poem yourself, and your child recites it back on the lock screen.

Learning-app time

Minutes spent in educational apps like Duolingo count towards unlocks, so time spent learning earns time for play.

Insights & privacy

See the progress, keep the data.

The parent dashboard shows more than minutes. See how many challenges were completed, which maths topics are strong and which need work, the questions that caused the most trouble, and a timeline of every quiz, walk and recitation.

  • Stays on the device. Your child's history and results are stored on their device. We never receive them.
  • No ads, no analytics. Nothing is selling to your kids or tracking them while they earn their time.
  • On-device camera counting. Pose detection runs on the device. No video is saved or uploaded.
  • Online only if you say so. No account is needed. A recovery email and sharing recitation text with us are optional, and off until a parent turns them on.

FAQ

Questions parents ask.

Is this a punishment app?

No. The goal isn't less screen time for its own sake — it's better screen time. Kids always have a way to earn more, and the challenges are designed to be quick and positive, not a chore.

What ages is it for?

It works best for roughly 6–12 year olds. You tell the app their school year, and choose which challenges are available, which times tables to practise, and how many steps or squats count, so you can tune it as they grow.

Will the recitation library be religious?

Only if you want it to be. The library is still being built. When it arrives it will be optional, with nothing switched on by default. Alongside texts from many faiths there will be poems and famous speeches, and you'll be able to add anything of your own, from a family prayer to a favourite rhyme.

Can my child bypass it?

The lock screen appears over the selected apps when time is up, and settings are behind your parent PIN. No app is impossible to get around for a determined child, but Tollo is built to make earning time easier than dodging it.

What if something goes wrong — or we just need an exception?

Your parent PIN can override the lock screen at any time. Long car journey, special occasion, or a challenge that isn't working — you're always in charge.

What if I forget my PIN?

When you create your PIN, the app gives you a recovery code to write down. You can also add a recovery email: tap "Forgot PIN?" and the app emails you a link that lets you set a new one.

Does it need an account or the internet?

No. Limits, challenges and history all work with no account and no connection. Two things go online, and only if you turn them on: a recovery email, and sharing recitation text to help us improve the app. Answering out loud uses your device's speech service, which on some devices needs a connection.

Is my child's data shared with anyone?

Not unless you choose to share it. Everything the app records about your child stays on the device, and we never receive it. There are no ads and no analytics, and squat counting happens on the device itself. The privacy policy sets out the two optional online features and how to delete everything.

Which devices are supported?

Android phones and tablets running Android 8.0 or newer.

Which permissions does it ask for?

Usage access and "display over other apps", to know when time is up and show the lock screen. The camera, microphone and step counting are asked for only if you switch on a challenge that uses them. The privacy policy lists each permission and why it's needed.

Ready for calmer evenings?

Tollo is in early testing. Leave your email and we'll let you know when it's ready for your family.
