A foldable-first Android launcher with a right-side dock.
iDuo Launcher is an experimental Android launcher designed around a foldable phone, a four-column Home grid, and a dock on the right that holds four to eight apps. The cover shows one Home page at a time. Unfolding adds an editable workspace on the left: the first view pairs that workspace with Home 1, followed by Home 1 + Home 2, Home 2 + Home 3, and so on.
On a fresh install, Welcome to iDuo offers Choose Home app, Add a widget, Explore Home, and Not now. Choosing or skipping setup does not prevent later changes.
To make iDuo the launcher, choose Set as home app at the top of Settings, or open Language, backup & Home app. Android owns the final Home-app chooser. To switch away later, choose Change home app, or use Android Settings → Apps → Default apps → Home app. The exact Android path may vary by device.
Long press an empty Home cell or any bare wallpaper on Home, such as the space below or beside the grid, to open Add to Home, then choose Add apps, Widgets, Wallpaper, or Customize launcher. Add apps lists every app not yet on Home, in the dock or in a folder: tick any number and they fill the page’s free cells from the one you held, then new pages after the last; the list shows how many pages that adds, such as +1 page. Settings opens over the whole screen. On the cover screen it lists its sections and opens one at a time; on the inner screen the list stays on the left beside the open section. Each row in the list shows its current setting, Search settings finds any setting by name, and cards at the top point out when iDuo is not the Home app or when Home gestures are off.
After a layout edit, Undo last layout change appears in customization. It covers the latest supported layout change, so use it before making another edit.
Hold an app, then drag it to an empty cell, another page, or a vacant dock position. Neighboring Home icons move aside when possible. Pause at the left or right screen edge while holding to turn a page. Past the last page, rest at the right edge for a little over a second to open an empty page and drop the app there to make a new Home page; one page is the cover screen or one half of the inner screen.
Dragging between Home and the dock moves the shortcut instead of duplicating it. The dock holds four apps by default; choose four to eight under Dock → Apps in dock. The dock background grows or shrinks with that number. Choosing fewer positions keeps every app: apps from removed positions fill empty dock positions first, then move to free Home cells. When the dock is full, iDuo shows Dock full • Move an app out first and rejects a new arrival; it never evicts an app automatically. Existing dock apps can still be reordered. Drag a Home or dock shortcut to Remove to remove the shortcut without uninstalling the app. Empty dock positions show recently opened apps, set apart from your own by a short line.
To make a folder, drag an app onto the middle of another Home app and hold it there for a moment: the target gains a folder-shaped backdrop, the other icons stop moving aside, and releasing groups both apps in a new folder in the target’s place. Drag an app onto the middle of an existing folder to add it straight away. Releasing near a cell’s edge still moves the app between neighbours as usual. Tap a folder to open it. Its name is the heading; tap the pencil beside it to rename the folder. The folder menu (⋮) offers Add apps, which lists the apps not in the folder to tick and add, and Choose apps, which ticks all of the folder’s apps at once: apps from Home, the dock or another folder move in, and apps left unticked go back to Home. It also moves the whole folder to another page or ungroups it, returning its apps to Home starting in the folder’s place. Make folder large turns a folder on Home into a large one that takes two by two places, like a folder in the App Library on iPhone: tap one of its three large icons to open that app, or its small icons in the last corner to open the folder. It grows where it is, or at the nearest free space on its page; if the page has none, the apps in its way move to the first free places. Drag it by any part to move it whole. It becomes small again with Make folder small, in the dock, or when fewer rows or columns leave no room for it. To take a single app out, hold it and drag it onto Home or the dock. An open folder is sized to its apps, up to six across and six down (fewer on the cover screen if they would not fit); more apps continue on further pages that you swipe between, with dots showing the current page. Home layout → Folder background transparency sets how much of Home shows through an open folder. This look setting stays on the device and is not part of layout backups.
Long press and release an app on Home, in the dock or in All apps for a menu beside it: the app’s own shortcuts, such as New tab or Compose (Android shares them only with the default Home app), then Remove, Uninstall (not offered for apps that came with the phone), Icon, App info and More, which opens options such as Move on Home and Create folder. In the dock, Change picks another app for that position. Icon chooses one drawing from an installed icon pack for this app alone, with search; Use the app’s own icon undoes it. All apps remains the complete installed-app catalog even when a shortcut is removed.
If Android exposes a managed profile, All apps shows Personal and Work filters. A paused profile shows Work apps are paused and Turn on work apps. Availability and cross-profile widget access remain controlled by the profile administrator.
Open Widgets from an empty-space menu, Add widget to this page under Settings → Home, or Add a widget during setup. Search the catalog, select Personal or Work when those choices exist, then tap a preview to place it or hold it to drag. Android may ask you to allow the binding, and some providers open their own setup screen.
Hold an existing widget to pick it up, then drag it across cells or pages. A small amount of held finger jitter is allowed. Move into the lower-right Remove target to delete it from Home. Long press and release without dragging to open Widget options, which can include Widget settings, Resize on Home, page moves, Replace, and Remove.
For Resize on Home, drag the resize handle and choose Apply, or choose Cancel. The alternate size controls end with Apply size. iDuo rejects sizes or moves that overlap another item, exceed the visible grid (four or, on the cover’s own Home, five columns by six to eight rows), or violate the provider’s allowed sizes.
iDuo remembers which app each widget comes from. A widget whose app is being updated returns by itself. If Android lets a widget go, iDuo connects the same widget again, or shows it by name with Reconnect when Android asks for permission or the widget needs its own setup.
Scrollable Android widgets keep their native vertical scrolling when the touch begins on scrollable provider content. A horizontal swipe can still change Home pages. Hold still before moving when you intend to pick up the widget.
iDuo shows your Android wallpaper, including live wallpapers, and follows any change made in Android’s settings. In Wallpaper & appearance, Your photo creates a private preview. Apply asks whether to set it on the Home screen, the Lock screen, or both, then sets it as the Android wallpaper; Cancel keeps the current wallpaper. If selection is interrupted, choose Resume or Cancel. Recovery has been checked for activity recreation and a completed private preview file, but an interruption during the earlier decode step may require selecting the photo again.
iDuo dunes sets the bundled dunes landscape as the Android wallpaper, asking for the same screens. Android wallpapers opens Android’s own wallpaper picker. In the photo’s preview, and later while it is the wallpaper, Move or zoom the photo (or tapping the preview) lets you drag and pinch it to pick the part each screen shows; the cover and inner screens keep their own part, and Reset fills the screen from the photo’s centre. Android wallpapers are adjusted in Android’s own picker. While a folder is open, the wallpaper is dimmed and softly blurred.
Color mode offers Light, Dark, System, and Sun, which follows sunrise and sunset. Sun accepts coordinates through Use this place, or requests approximate location only when you choose Use device location. If location is unavailable, iDuo visibly falls back to the system theme. Clear location removes saved coordinates; iDuo does not request location in the background.
Install an icon pack from Google Play (search for “icon pack”; iDuo reads packs made for launchers such as Nova), then choose it under Settings → Wallpaper & appearance → Icon pack, which also links to the store. Apps the pack does not draw keep their own icon, placed on the pack’s backdrop when it has one. Choose App icons to return to the apps’ own icons.
The cover screen stays upright. Rotate the cover screen under Settings → Home → Screen lets it turn with the phone; this is experimental and landscape may not look right yet. The inner screen always follows the phone.
Notification badges under Settings → Home puts a red badge on apps on Home and in the dock with the number of their waiting notifications, the total on folders, with a small dot on each of a folder’s small icons that has notifications; inside an open folder each app shows its own badge. It needs notification access, which the switch opens in Android’s settings. iDuo only counts notifications per app; ongoing ones, such as music or a running timer, and apps whose badges are off in Android’s settings do not count.
As you fold or unfold the phone, the half of the inner screen that swings, the side away from the dock, tilts away from you, blurs and darkens toward its edge, then comes into focus once the phone is open flat. On the cover screen Home arrives tilted away from the hinge and comes into focus. The animation starts when Android switches screens, so it cannot appear before the inner screen lights up. Folding animation under Settings → Home → Screen switches it off; it needs Android 13 or later.
Language, backup & Home app in Settings lists System language first, which follows Android and shows the language it currently resolves to. The other choices are English, Čeština, Slovenčina, Polski, and Deutsch, each shown in its own language. On Android 13 and later the same choice also appears in Android Settings under the app’s language.
Swipe up on Home to search. Matching apps appear in up to two rows as you type; tap one to open it. The keyboard’s search key or the magnifier in the field opens Google’s results for the phrase. Back or a tap outside the panel closes it.
On Home, swipe down from the left 70% to open Notifications or from the right 30% to open Quick Settings, and double-tap empty space to lock the screen. Locking works like the power button, so fingerprint and face unlock stay available. The first attempt offers Turn on Home gestures because Android requires you to enable iDuo Launcher in Accessibility settings. This is optional and must be enabled by you; Not now leaves it off. The service only requests the system panel and lock actions. Each gesture has its own switch under Gestures & search, which also shows whether the service is on.
Open Language, backup & Home app, choose Save under Layout backup, and select a document destination. Choose Restore to select a backup, inspect Review restored layout, then choose Restore again. Cancel leaves Home unchanged.
Backups contain Home and dock positions, folders, widget descriptions and spaces, layout presets, labels, search behavior, and status settings. They include the unfolded-only workspace. They do not include the selected background photo or live Android widget bindings. After restore, provider widgets keep their saved space but require Reconnect; unavailable apps leave empty positions, and work-profile entries may need manual placement. Review a backup before sharing because it can expose app names, folder names, and profile metadata.
