Getting Started
What is WALL-E?
WALL-E is a curated wallpaper app offering high-resolution still wallpapers and silent live wallpapers for your devices. Browse the gallery, save favourites, build collections, and download wallpapers using credits.
Signing in
WALL-E uses your miiso.dev account — sign in with email & password or Google. Your account, credits, and downloads are shared across all miiso.dev products.
Your first download
Tap any wallpaper to open the viewer, then hit Download. A still costs 1 credit and a live wallpaper costs 5 — the button always shows the price before you press it. You won't be charged again for a wallpaper you've already unlocked.
Live wallpapers
Some wallpapers move. They are short, silent loops built to sit behind a lock screen — ambient motion with a fixed camera, not a video. Look for the Live badge on a card, or use the Motion filter on Discover. A live wallpaper costs 5 credits where a still costs 1 — it is a much bigger asset and far more expensive to make. It downloads as an MP4 you set as a live or video wallpaper in your phone's own wallpaper settings. Before you buy, the gallery shows a still frame from the loop; the loop itself plays in the viewer once it is yours.
Credits & Billing
What are credits?
Credits are WALL-E's currency — a still costs 1 and a live wallpaper costs 5. Credits never expire while your account is active and are non-transferable between accounts.
Buying credits
Open the Credits page from the account dock. Choose a credit pack and complete checkout via Polar (our payment partner). Credits are added to your balance instantly on successful payment.
Refunds
All sales are final. We may, at our discretion, issue refunds for duplicate purchases or technical failures. Contact legal@miiso.dev within 14 days of purchase.
Library & Collections
Discovering wallpapers
The Discover tab shows the full library. Use the search and category filters to narrow results. Tap the heart icon to save a wallpaper to your Favourites.
Collections
Collections let you curate wallpapers into themed sets. Create a collection from the Collections tab, add wallpapers from the viewer, and optionally publish it to your public profile.
Your downloads
All wallpapers you've ever downloaded appear in the Downloads tab. Re-downloading a wallpaper you've already paid for won't cost a credit.
Profiles & Social
Your public profile
Your profile lives at /u/your-username. It shows your published collections and lets other users follow you. Update your display name, bio, and avatar from your account settings on miiso.dev.
Following
Follow other users to stay up to date with their published collections. You'll receive a notification when someone follows you or likes one of your collections.
Account & Privacy
Account settings
Account management (password, email, connected providers, deletion) is handled on miiso.dev — your shared account hub.
Data & privacy
WALL-E collects only what's needed to run the service. Read the Privacy Policy for details. Analytics only fire after you accept the cookie notice.
Deleting your account
You can request account deletion from your miiso.dev settings. Unused credits are forfeited on deletion. Downloaded wallpapers on your device are yours to keep under the personal use licence.
Troubleshooting
Download failed
If a download fails after debiting a credit, refresh the Downloads tab — the file is usually cached. If the credit was deducted but the file is missing, contact us and we'll restore it.
Payment not going through
Checkout is powered by Polar. Check that your card details are correct and that your bank isn't blocking the transaction. If the problem persists, try a different browser or contact Polar support.
Can't sign in
Make sure you're using the same provider you signed up with (email or Google). Use the Forgot password flow if needed. If you're still locked out, contact us.
