Solving a linear equation
In one sentence
To solve ax + b = c, do the opposite: take b away, then divide by a.
Understand
- Isolate x by undoing the operations in reverse order.
- Take 5 away from both sides: 3x = 15.
- Divide both sides by 3.
The rule
Check you've got it
What is x if 2x + 4 = 10?
Homework
2 ÷ ⅔ = ?
= ⅓ ??
Show your exercise to the camera and ask your question out loud.
Count how many ⅔ fit in 2. Three of them! That is why dividing by ⅔ means multiplying by 3/2.

Sound familiar?
You got it in class. Then you opened your homework.
Lumino starts from the exact spot where you're stuck, in your subject and at your grade. Pick the line that sounds like you.
That gap between class and homework is exactly where Lumino helps.
How it works
Three ways to ask. One clear explanation.
Every explanation becomes a summary card with the key points, the formula and a quick quiz, so you can find it again before the test.
Built to teach
Lumino explains. You write the answer.
You get the method, the reason behind each step and a quick quiz to check it stuck. The homework you hand in stays yours.
For parents: help that teaches at 9 p.m., when nobody else is around to explain fractions.
On your iPhone
Your streak follows you to the Lock Screen.
A Live Activity shows today's progress and the time left to keep your streak. On iPhones with a Dynamic Island, it sits right around the camera.

Rate how well you got a card. Lumino brings it back at the right time: tomorrow if it's still shaky, in 2 days if it's almost there, then 7, 14 and 30 days once you've got it.

FAQ
Questions students and parents ask
Pick a topic. Tap a question to open the answer.
Does Lumino do my homework for me?
No. Lumino explains the method and the reasoning so you can do the exercise yourself, then checks you understood with a short quiz.
Which subjects and grades does it cover?
Math, English, science, biology, history, geography and languages, from grade 4 to college. You can also type any other subject, like Latin or computer science.
What if I still don't get the explanation?
Open the summary card and continue the session to ask a follow-up in your own words. You can also switch to Live Tutor, show your page to the camera and talk it through.
Can I use Lumino to study for a test?
Yes. Every explanation is saved as a summary card with the key points, the formula and a quiz. The Review tab brings each card back tomorrow, in 2 days, or after 7, 14 and 30 days, depending on how well you knew it.
How does the streak work?
Your streak counts the days in a row you learn with Lumino. Your daily goal sets how many notions make a day count, and the Live Activity shows how much time is left before midnight.
How is Lumino different from an answer app?
Lumino is built to explain. Your child gets the steps and the reason behind each one, then a quick quiz. The homework they hand in is their own work.
Can I see how my child is doing?
The Progress tab shows the streak, the notions understood, the current level and the goal your child set.
Will Lumino send a lot of notifications?
One reminder a day at most, at a useful moment like homework time or before a test. Notifications can be turned off anytime.
What happens to my child's answers and data?
The answers given during setup are only used to fit Lumino to your child's grade, subjects and pace.
How much does Lumino cost?
$69.99 a year (about $5.83 a month) with a 7-day free trial, or $9.99 a month, billed right away. Both plans include everything.
How does the free trial work?
Choose the yearly plan and you get 7 days free. Nothing is charged during those 7 days. Cancel before the end and you pay nothing.
How do I cancel?
On iPhone: Settings, tap your name, then Subscriptions. On Android: open Google Play, tap your profile, then Payments & subscriptions. Your plan stays active until the end of the period you paid for.
Can I get a refund?
Payments go through the App Store or Google Play, so refunds follow Apple's and Google's refund policies. You can request one from your purchase history.
What if I switch phones?
Back up your progress with Apple, Google or your email. Sign in on the new phone and your streak and notions come back.
When can I download Lumino?
Lumino is coming soon to the App Store and Google Play.
Does it work on Android?
Yes, Lumino is coming to both iPhone and Android. The Live Activity and the Dynamic Island are iPhone features.
Which iPhones show the Dynamic Island?
The Dynamic Island is on iPhone 14 Pro and newer models. Other iPhones still show the Live Activity on the Lock Screen.
Do I need an internet connection?
