Works offline. Forever.
FreeDrawColour is a Progressive Web App. Install it on your phone, tablet, or computer, and the entire app + every template stays on your device. After the first load, you never need the internet again.
How the offline story works
When you first visit freedrawcolour.com, a service worker registers in the background. The service worker pre-caches the app shell, the 12 templates, the icons, and the manifest. After that first visit, the app serves itself entirely from your device's storage — even on Airplane Mode, even with no SIM, even in a basement.
What works offline
- All 12 colouring templates (cached as static files on first load).
- Freehand drawing with pressure + tilt.
- Tap-to-fill (flood-fill is local; it doesn't need a server).
- Saving up to 100 artworks in My Art.
- Two-finger pan and pinch zoom.
- Daily free page: the date math is local, so the daily card works offline too.
- Streak: based on local dates, never the network.
- Autosave: the colour layer is snapshotted to localStorage every 5 s, so a crash or a refresh never loses work.
Why we built it this way
Because we're a colouring app. The whole point is that you can be in the back seat of a car with no Wi-Fi, and still finish your masterpiece. Other apps in this category require an internet connection to do anything meaningful because their content library is server-side. We don't have that problem because our 12 templates are 12 small SVG files. We can ship them all with the app, and we do.
