The alternative.me roundup on foldable keyboards, mice, and accessories sits next to a Galaxy Z Fold and a Z Flip refresh that quietly grew the foldable user base again this year. The hardware is good. The default software story is uneven, with most flagship apps still treating the foldable as a small tablet rather than a phone that turns into one. We tested seven Android apps that actually understand foldable form factors, ranking on cover-screen behavior, split-screen handling, dual-pane content, and how they fall back on a regular phone when needed. These are the best apps for foldable phones on Android in 2026.
What to look for in a foldable-friendly app
The hardware does its part. The software has to meet it halfway.
- Cover-screen behavior. On a Z Flip, the small outer display is the cheapest input most users miss. Apps that draw something useful on the cover earn the spot.
- Split-screen aware layouts. On a Z Fold, the open-state UI should rearrange, not just scale up. Two-pane reading apps, dual-app launchers, and proper drag-and-drop separate good from great.
- Continuity. Closing the fold or opening it should never lose state. The picks that handle the transition cleanly are the ones worth keeping.
- Hinge friendliness. Apps that crash on configuration change are still surprisingly common. The picks here survive five rapid open-and-closes without restart.

The 7 best apps for foldable phones on Android in 2026
1. Good Lock, the Samsung foldable customization suite
Good Lock is the umbrella app for Samsung’s official customization modules. On a Z Fold or Z Flip, the modules that matter most are MultiStar (split-screen and dual-app drag), Routines+ (auto-actions when the fold opens or closes), Wonderland (lock-screen and cover-screen wallpapers), and NavStar (one-hand navigation tuned for the narrow front display). Each module is a separate installer that runs through the Galaxy Store, with Good Lock as the launcher.
Good Lock unlocks the kind of foldable customization the stock UI hides. Auto-rotating the home screen when the phone unfolds, putting custom widgets on the cover screen, and pinning two apps side by side from one tap are all module-level features.
Where it falls short: Samsung Galaxy only. Each module is a separate install with separate updates. The modules ship with regional variation, and a few launch only in Korea before reaching other markets.
Pricing:
- Free.
Platforms: Samsung Galaxy (Android One UI).
Bottom line: The right pick for any Galaxy Z Fold or Z Flip user. It is the closest thing to a foldable settings panel.
2. NiceLock, the Good Lock helper for non-Korean Galaxy users
NiceLock is the third-party helper that installs and updates Good Lock modules outside the markets where Samsung ships them directly. The interface mirrors Good Lock with module installers organized by category, plus a few exclusives the developer ports from internal Samsung builds. For a Galaxy owner in a market where the Galaxy Store does not stock every module, NiceLock is the only way to actually run them.
Pair NiceLock with Good Lock itself. Use NiceLock to install modules that are not in your regional Galaxy Store; once installed, the modules show up inside Good Lock as if they had come from there.
Where it falls short: Distribution outside the Play Store needs sideloading, which means turning on install-from-unknown-sources for one trusted source. NiceLock has no use on non-Samsung phones.
Pricing:
- Free.
Platforms: Samsung Galaxy.
Bottom line: The right pick when Samsung’s regional rollout for Good Lock modules has left you behind.
3. Microsoft Launcher, the foldable-aware launcher
Microsoft Launcher is one of the few major launchers that explicitly handles foldable transitions. The home-screen grid reflows when the fold opens, the feed panel shows a two-column layout on the larger display, and the lock-screen handoff between the cover and inner screens is smoother than the stock One UI launcher. The Microsoft 365 hooks (calendar, To Do, OneDrive) are a bonus rather than the headline.
For a Z Fold, the larger feed pane is the genuine improvement over a phone-sized launcher.
Where it falls short: Battery usage is heavier than minimalist launchers. The Microsoft 365 hooks are only meaningful with an active account. Some animations skip on older phones.
Pricing:
- Free.
Platforms: Android.
Bottom line: The right pick when you want a launcher that handles the fold transition without intervention.
4. Nova Launcher, the custom dual-pane grids
Nova Launcher is the launcher most foldable power users settle on. Two separate home-screen grid layouts for folded and unfolded states, custom icon scaling per state, and per-app shortcuts to either grid all live in the Nova Settings menu. The launcher is also the most reliable on rapid open-and-close transitions, with no app-state loss across the hundreds of folds a Z Flip does in a typical day.
The 2026 release added an explicit foldable-aware tab in the settings, replacing the older “tablet mode” workaround.
Where it falls short: Setup is a focused hour, especially for users who want the per-state grids dialed in. The free version covers most needs; Nova Prime adds gestures, custom drawer groups, and unread badges.
Pricing:
- Free.
- Paid: optional Nova Prime upgrade.
Platforms: Android.
Bottom line: The right pick when you want to tune the home screen separately for folded and open states.
5. Drawer Bar, the edge-screen quick launcher
Drawer Bar is the third-party take on Samsung’s Edge Panel, with the addition of a separate panel for the Z Flip cover screen. The panel sits at the edge of either display, swipes out into a launcher for apps, contacts, and shortcuts, and remembers which panel it lives on. On a Z Flip, the cover-screen variant gives the small outer display a real launcher rather than the limited widget set.
Pair Drawer Bar with the Samsung MultiStar module for split-screen drag-and-drop and the workflow gets close to a real one-handed dual-app experience.
Where it falls short: Battery drain is moderate, especially with both panels active. The settings menu is dense.
Pricing:
- Free.
- Paid: optional Pro upgrade.
Platforms: Android.
Bottom line: The right pick when you want the cover screen to actually launch apps rather than just show widgets.
6. Squid, the stylus-friendly notes app
Squid is the digital notebook that turns a Z Fold into a real reMarkable-style notepad when the S Pen comes out. The split-pane layout displays a notebook on the left and a PDF, web article, or research source on the right, with palm rejection that survives the inner display’s flexible surface. Annotation tools include shape recognition, infinite-canvas pages, and laser pointer for presentations.
For a Z Fold owner who actually uses the S Pen, Squid is the app that justifies the screen size for note-taking.
Where it falls short: The free tier covers basic notes; advanced features (PDF import, ink-to-text) need Squid Premium. The Z Flip version of the app does not benefit from the larger canvas.
Pricing:
- Free.
- Paid: optional Premium subscription.
Platforms: Android.
Bottom line: The right pick when the S Pen and the larger inner display are the reason you bought the Fold.
7. Moon+ Reader Pro, the two-page reading app
Moon+ Reader Pro is the long-running e-book reader that earns a foldable slot for one feature: the two-page spread on the Z Fold’s inner display. When the fold opens, the reader switches to a book-style two-page view that paginates like a paperback, with margins and gutter that match the hinge position. The page-turn animation respects the hinge, which is the kind of small detail that separates apps built for foldables from apps that merely render larger.
The reader handles ePub, PDF, Mobi, FB2, and a handful of legacy formats. Sync via Dropbox or Google Drive keeps your library consistent across devices.
Where it falls short: UI is dated. Setup requires choosing among several themes that look like 2014. The two-page mode does not benefit Z Flip users.
Pricing:
- Paid: one-time purchase for Pro, with a separate free ad-supported edition.
Platforms: Android.
Bottom line: The right pick when you bought a Z Fold partly to read more, and partly to read in a hinge-aware layout.
How to pick the right one
- If you own a Samsung Galaxy foldable: start with Good Lock.
- If Good Lock’s modules are missing in your region: pair with NiceLock.
- If you want a launcher that survives the fold transition: pick Microsoft Launcher.
- If you want per-state custom home screens: pick Nova Launcher.
- If the cover screen needs a real launcher: pick Drawer Bar.
- If you actually use the S Pen: pick Squid.
- If you bought the Fold partly to read: pick Moon+ Reader Pro.
FAQ
What is the best customization app for a Samsung Galaxy Z Fold? Good Lock with the MultiStar, Routines+, and Wonderland modules covers most of the customization the stock UI hides. NiceLock helps in regions where Samsung does not distribute every module.
Can I use Good Lock on a non-Samsung foldable? No. Good Lock is tied to Samsung’s One UI. Pixel Fold and OnePlus Open users should look at Nova Launcher, Microsoft Launcher, and Drawer Bar for similar functionality.
Which apps actually use the Z Flip cover screen? Drawer Bar’s cover panel adds a real launcher. The Samsung MultiStar module exposes more apps to the cover display. A growing list of third-party apps (Spotify, Google Maps) renders dedicated cover screens that the system permits.
Do these apps drain extra battery on a foldable? Good Lock and NiceLock are light. Microsoft Launcher and Drawer Bar are medium. Nova Launcher is light if you avoid live wallpapers. Battery use scales with the number of active edge panels and custom cover-screen widgets.
Is there a single app that handles everything foldable? No, and there shouldn’t be. The picks here are deliberately narrow: each does one job for the form factor and gets out of the way.
