Brushes that answer to your hand
Watercolour that pools, pastel that grains, a marker that overlaps like a real marker. Press harder with an S Pen and the line swells. A blender that moves the paint already on the page — and never adds any.

Why it feels different
Most colouring apps are a bucket tool with a library.
Linometry is a studio.
Colour never leaks past the lines
Every page is cut into segments before you ever see it. A stroke stays inside the segment it started in, so a big loose scribble fills a petal perfectly. Turn it off when you want to paint free-hand.
Sharp at any zoom
Pages are vector line art, not pictures of line art. Zoom into a mandala's centre and the ink is still crisp, your paint is still smooth, and the page is still fast — on a phone or a 12-inch tablet.
The library
A new free page every single day.
Mandalas, animals, florals, botanicals, colour-by-number, greyscale portraits — hand-finished so the segments are right, sorted into books, searchable in fifteen languages. Today's free page is yours to keep if you claim it today.
Start colouring freeMake your own
Type a sentence. Or use a photo. Get a page.
Your dog. Your street. A dragon in a teacup. Describe it or import a photo and Linometry draws it as a proper colouring page — segmented, so it colours like the rest. Photos are cropped on your device and the original is never kept.
- Premium includes three pages a day; packs never expire
- If a page fails to generate, the coin comes straight back
- Pages you make are yours to colour, share and print
Tablet & stylus
Built for a pen, happy with a finger.
Pressure on S Pen and USI styluses. Palm rejection that ignores your hand and not your pen. Two-finger zoom and rotate, two-finger tap to undo. A stroke engine that runs on the GPU so the line lands where the nib is, not a beat behind.
Colouring with children
Simple mode: size and colour, nothing else.
Tell the app you colour with kids and it hides the tone and opacity sliders, keeps stay-within-the-lines on, and puts the kids' shelf first. Big brushes, bright colours, no wrong moves.

Questions
Straight answers.
Is Linometry free?
Yes. You can colour for free with no account and no card: the free pages, the free brushes (Technical, Pencil, Marker, Felt tip) and a brand-new free page every day. Premium adds every brush, every book, watermark-free export and three AI coins a day. Nothing that was ever free becomes paid.
Does it work with a stylus like the S Pen?
Yes. Brushes respond to stylus pressure on Samsung S Pen and USI styluses, palm rejection keeps your hand off the page, and the stroke engine is built to keep up with fast pen movement on tablets. It works just as well with a finger on a phone.
Can I colour outside the lines by accident?
Not unless you want to. Every page is split into segments, and with Stay within the lines on, a stroke stays inside the segment it started in. Turn it off for free-hand painting across the whole page.
Can I make my own colouring pages?
Yes. Type a sentence or import a photo and Linometry turns it into a colouring page. One page costs one coin; Premium includes three coins a day, and coin packs never expire. Photos are cropped on your device and the original is never kept.
Is it suitable for children?
Yes. Simple mode hides the advanced sliders and leaves just brush size and colour, and pages tagged for kids sit in their own shelf. Simple mode switches on automatically when you tell the app you colour with children.
Which devices does it support?
Android 8.0 or later, phones and tablets. Devices with less than 4 GB of memory draw pages at a lower resolution so colouring stays smooth. An iPhone and iPad version is planned.
Does my artwork sync between my phone and tablet?
Yes. With a free account your artwork saves on the device continuously and syncs to your account when you are online, so a page you start on the phone is waiting on the tablet.
How do I cancel Premium?
Premium is billed by Google Play, so you cancel there: Play Store → Payments & subscriptions → Subscriptions → Linometry. Anything you have started stays editable and exportable whatever happens to your subscription.
Your first page is waiting.
