Wallpapers 4K – Gradient HD

FightTech VN

About this app

A small, quiet wallpaper app. Hand-drawn 4K gradients, a maker that generates new patterns, your own photos, and a schedule that actually keeps running. Everything ships inside the download — it works in airplane mode, and it never asks for an account.

🖼 TRUE 4K, DRAWN IN-HOUSE
• Every wallpaper is 2160×3840 — razor sharp on any phone
• Original artwork made for this app, not stock photos
• Three collections: Gradient, Abstract and Minimal
• Deep, near-black designs that look right on AMOLED screens

🎛 A MAKER THAT NEVER RUNS OUT
• Six pattern styles: gradient, mesh, geometric, stripes, dots, waves
• Pick two colours and a direction, or shuffle for instant ideas
• Keep the ones you like — they become a collection of their own
• A pattern is a few dozen bytes, so a saved one costs no storage at all

📷 YOUR OWN PHOTOS
• Add photos through the system file picker — no photo-library permission
• They join the rotation like any other wallpaper
• Long-press to remove one

🖌 CROP AND ADJUST
• Preview full-screen, cropped to your exact display
• Nudge blur, dim and colour strength before you set it
• See how it will look behind your clock and icons

🔁 AUTO-CHANGE THAT KEEPS RUNNING
• Every 15 minutes, every few hours, or once a day
• HOME SCREEN AND LOCK SCREEN CAN NOW GET TWO DIFFERENT IMAGES — one picked for each, every turn
• Sources: the whole collection, your favourites, your photos, your saved patterns, a brand-new pattern each time, or one image per time of day
• Prefer darker images in dark mode or battery saver
• The schedule is rebuilt after a reboot, an app update, or a force stop — the one thing wallpaper apps quietly get wrong

⚡ CHANGE IT RIGHT NOW
• A quick settings tile in the pull-down panel
• A one-button widget on the home screen
• A shortcut when you long-press the app icon
• None of them disturbs your schedule

📋 WALLPAPER HISTORY
• The last 50 wallpapers the app set
• Set one again if you miss it
• Ban one and it never comes round again
• Kept on this phone, nowhere else

🌊 LIVE WALLPAPER
• A slow crossfade through a playlist of your choosing
• Pauses when the screen is off, so it costs almost nothing

🔒 GENUINELY OFFLINE
• The app has no internet permission at all — it cannot phone home
• No account, no sign-in, no email
• No ads and no ad SDK; anonymous usage stats can be switched off in Settings
• Your photos never leave your phone

💛 FREE, WITH NO CATCH
No ads. No subscription. No locked "premium packs". Everything described above is in the free app and will stay there.

What’s new

• A true preview with the clock, plus a warning when text would be hard to read.
• The image cache can be capped and cleared.
• Critical fix: wallpapers came out stretched because the preview and the apply step cropped to different ratios.
• Fixed: Android 7–9 always reported “save failed” even when the save worked.
