    Getting Started

    What is WALL-E?

    WALL-E is a curated wallpaper app offering still and 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, Google, or Apple. 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. Each download costs 1 credit. You won't be charged again for a wallpaper you've already unlocked.

    Credits & Billing

    What are credits?

    Credits are WALL-E's currency — 1 credit = 1 wallpaper download. 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, Google, or Apple). Use the Forgot password flow if needed. If you're still locked out, contact us.
