Kaela

Tonight’s worksheet is the password.

Photograph tonight’s worksheet. Kaela turns it into a short lesson and a quiz built from that page. Their phone stays locked until they score 80%, marked on our server, in about two seconds.

80% is a pass. Missing one still opens the phone.

No card to join. Android first.

How it works

Thirty seconds of your night. Fifteen minutes of theirs.

No timetable to build, no rules to configure, no dashboard to learn. You photograph what came home in the school bag.

  1. 3/4 + 1/8 =2/3 of 18 =

    01

    3 taps

    You photograph the page

    Open Kaela, point at the worksheet, confirm. Three taps and you are done. A PDF works the same way.

  2. 3/4+1/8= 7/8RecallApplyStretch

    02

    About 15 minutes

    They get a lesson built from that page

    Three or four minutes, mostly drawn rather than written. Then a quiz sized to what you photographed, in three tiers: recall it, use it, stretch it.

  3. 80%

    03

    About 2 seconds

    80% opens the phone

    Marked on our server, not on the handset, so a device that claims it passed is not a device that passed.

And when they miss. Two minutes on only the parts they got wrong, then a fresh set of questions. Never the same questions twice, no waiting period, no cap on attempts. There is no version of this where the phone cannot be opened by doing the work.

How the tutor works

It teaches the page in the school bag, not a topic it picked.

Five steps, every time, in about fifteen seconds of setup. Here is the whole of it. There is no sixth step where it phones a human.

  1. 01

    Their work, not a syllabus

    It reads the page you sent

    Not a topic guess from a year level. The questions on that sheet, in the order that sheet asks them.

  2. 02

    One idea at a time

    It works out what is being taught

    Twelve fraction sums are one idea, not twelve. The lesson is built around the idea, so getting it fixes all twelve.

  3. 03

    3–4 minutes

    It teaches, mostly by drawing

    Bars, blocks and number lines before sentences. A child who could already read the explanation would not have needed the lesson.

  4. 04

    Recall, apply, stretch

    It asks as many questions as the page needs

    A half page of times tables is not a two-page worksheet on fractions, so the quiz is sized to what came home rather than to a number we picked. Three tiers either way, and fresh numbers every attempt, so nothing is memorisable and nothing is answerable by pattern-matching the last set.

  5. 05

    About 2 seconds

    It marks on our server

    Never on the handset. A phone that claims it passed is not a phone that passed, and 80% is the only thing that opens it.

What it takes

Whatever came home in the school bag.

There is no subject list to check against, because Kaela does not teach a subject. It teaches the page you photographed. If it is legible, it is a lesson.

On the handset

Four screens, captured off a real Pixel 5.

Not renders and not mock-ups. These are the phone's own screen captures from the proof run — a Google Pixel 5 on Android 14, 1080×2340, uncropped. The handset drawn around them is an illustration; the screens inside it are not. The offline lock screen shipped after that run and has no capture yet, so it is not here. It is in the playable demo.

The honest bit

Two locks on Android. One of them can be beaten.

Every product in this category implies the lock is unbreakable. One of ours nearly is. The other is not, and you should know which one you are installing before your kid finds out first.

AndroidRecommended

Max Lock

Very hard to remove

Setup: About 20 minutes

Needs a factory reset first. You will set the phone up again from scratch: apps, logins, photos restored from backup. It is one evening, once.

What a determined kid can do

Very little. Kaela runs as the device owner, so it cannot be uninstalled, disabled in Settings, or cleared by a reset from the handset. Getting it off means a computer, a cable and deliberate effort.

Best for

Almost everyone. This is the lock that does what the product says it does, and the twenty minutes buys you never having this conversation again.

AndroidLighter touch

Standard Lock

Holds up to normal effort

Setup: About 2 minutes

No reset. Grant two permissions and it is running.

What a determined kid can do

More than we would like. Safe mode, developer options and a couple of other routes are open to whoever owns the phone, and a teenager who searches for it will find them. Android leaves those doors open on purpose and we cannot close them from an app.

Best for

A household that does not want a factory reset in it, or a kid you would rather not hand a locked-down phone to. It is the lighter touch, and it is lighter in both directions.

Both tiers run the same product and both have been run on a real Pixel 5. Lessons, quizzes, the override and the survival list are identical. The only difference is how hard the lock is to remove. Take Max Lock unless the reset is the thing stopping you — and if it is, Standard now and Max later loses you nothing. More on uninstalling.

iPhoneComing soon

iPhone is coming soon. Join the waitlist.

Locking an iPhone means using Apple’s Screen Time framework, and Apple has to grant an entitlement before anyone can touch it. They have granted ours. That was the part outside our control and it is done.

What is left is ours: the lock is written but has not run on a real iPhone yet, and it still has to pass App Review. We are not naming a date, because we would be guessing at Apple’s queue as well as our own. Until it locks a phone we will not sell you anything for one.

One email, the day it actually locks a phone. Not before.

Privacy

A lock, not a listening device.

You are being asked to install software on your child's phone. That deserves more than a link in the footer, so here it is in the middle of the page.

  • Stored in Sydney

    Database and uploaded files sit in the ap-southeast-2 region. Our API runs there too.

  • Training is opt-in, and off

    We do not train on your child's work unless you switch it on. The switch starts off and says what it does.

  • No analytics SDKs in the kid app

    Not one. No Firebase Analytics, no Meta SDK, no attribution kit. The kid app talks to us and to nobody else.

  • Export in one tap

    Everything we hold about your family, in a file, whenever you want it.

  • Delete in one tap, and it is real

    Rows and files removed, not hidden behind a deleted flag.

  • No screenshots, no keystrokes, no location

    We do not log which apps they opened or for how long. The report is about what they are learning.

Where your child’s worksheet actually goes

  1. 1

    The page you photograph

    Leaves your phone over an encrypted connection. Location data is stripped from the image before anything is stored.

  2. 2

    Kaela, Sydney

    Stored here, in Australia. Private buckets, short-lived links, one family cannot read another's rows.

  3. 3

    Our AI provider, overseas

    The text and the photo of their working go here to be turned into a lesson, a quiz and a mark. Not retained for training. This is the one hop that leaves Australia and we are not going to bury it.

Plenty of products say “Australian servers” and let you assume the AI is Australian too. Ours are, and it is not. Our servers and your stored data are in Sydney; the model runs on our AI provider’s infrastructure overseas.

Sunday morning

A weekly report that coaches, not one that spies.

No per-minute logs, no screenshots, no list of the apps they opened. What they are getting better at, where they are stuck, and one thing worth trying this week.

Where she is, topic by topic

Percentage correct across the last fortnight. The amber bar is the weak spot, called out underneath.

Percentage correct by topic
TopicCorrect
Equivalent fractions92%
Adding fractions84%
Times tables81%
Fractions to decimals46%

What is clicking

Equivalent fractions. She got every one of them, and she is getting there faster than she was a fortnight ago.

The weak spot

Turning a fraction into a decimal. Two out of five across the last two quizzes, and she pauses a long time before answering.

One thing to try

Ask her to say 3/4 as a decimal out loud at dinner. She gets there when she talks it through and stalls when she writes it down.
