Foldable Android phones now handle two typing surfaces on the same device: a narrow one-hand phone slab when closed, and a tablet-width thumb-spread when open. Most stock keyboards were built for one form factor and stretched into the other. The best keyboard apps for foldable Android phones are the seven that treat both halves as first-class layouts and switch between them without a wrestle.
We picked keyboards that ship a real split or thumbs mode for the unfolded state, keep learning across posture changes, and either work offline or make it clear when a prediction round-trips a server.
What to look for in a foldable keyboard app
The device changes shape mid-conversation. The keyboard has to follow it.
- A split or thumbs layout for the unfolded tablet width, not just a stretched phone bar.
- Automatic switch between phone and tablet modes when the device folds or unfolds.
- Swipe or glide typing that reflows to the new width rather than resetting.
- Offline mode for when you type sensitive text and do not want it sent for prediction.
- Custom key sizing on the outer keyboard so a thumb-only typist keeps landing hits.
- A calm approach to what the app sends to its servers, and a settings page that says so plainly.

The apps
1. Microsoft SwiftKey
Microsoft SwiftKey has shipped a thumbs mode on tablets for years, and on unfolded foldables it splits into two half-keyboards with a gap in the middle, which is exactly the layout thumbs typing wants. On the folded outer display it collapses back to a single narrow slab. Learning stays cross-posture: what SwiftKey learns about your typing habits carries between phone and tablet modes.
Where it falls short: Microsoft account sign-in is pushed hard, and privacy-conscious users should check the toggles. Prediction sometimes leans heavily on the cloud sync.
Pricing:
- Free: full app
- Paid: not applicable
Platforms: Android
Download: Google Play
Bottom line: the strongest single pick for a foldable owner who wants a split-thumbs mode that just works.
2. Gboard
Gboard ships a one-handed mode and a split mode that activate cleanly on unfolded foldables. Language support is the widest in the industry, glide typing is fast, and the Assistant integration is genuinely useful for translation and Emoji Kitchen mash-ups. On the folded outer display it defaults to a compact one-hand layout without prompting.
Where it falls short: the split mode is less thumb-optimised than SwiftKey’s. Some prediction features rely on account sign-in and Google services.
Pricing:
- Free: full app
- Paid: not applicable
Platforms: Android
Download: Google Play
Bottom line: the pick if language coverage or Google integration matters more than a hand-tuned split.
3. Fleksy
Fleksy is the customisation-first pick. Themes, layouts, and gesture bindings all get more attention than in the platform defaults, and the outer-display layout can be shrunk further for thumb-only typing. On the unfolded panel it supports a split layout with adjustable key sizes.
Where it falls short: the free tier limits some themes and features. Fleksy is a smaller company than Microsoft or Google, and the release cadence matches.
Pricing:
- Free: full base app with limited themes
- Paid: optional subscription for advanced features
Platforms: Android
Download: Google Play
Bottom line: the pick when you want deep customisation on both surfaces.
4. Typewise
Typewise replaces the QWERTY grid with a honeycomb layout that treats every key as an equal-sized target. That is the design choice that pays off on foldables: the same layout scales from phone to tablet without a redesign, and the larger targets suit thumb-first typing on the outer display. Full offline processing.
Where it falls short: the honeycomb takes a few days to unlearn QWERTY muscle memory. It does not ship a split mode because the layout does not need one.
Pricing:
- Free: full base app
- Paid: optional subscription for advanced features
Platforms: Android
Download: Google Play
Bottom line: the pick if you are willing to relearn a layout that scales cleanly across form factors.
5. Simple Keyboard
Simple Keyboard does the opposite of every other keyboard on this list: no prediction, no suggestions, no telemetry, no cloud. Just a keyboard. On a foldable that is a rare posture, and it fits when the priority is a keyboard that does not send anything anywhere. On the outer display it is a narrow slab, and on the inner it stretches to a tablet width without a split.
Where it falls short: no split, no glide, no prediction. That is deliberate.
Pricing:
- Free: yes
- Paid: not applicable
Platforms: Android
Download: Google Play
Bottom line: the pick when privacy trumps every other feature.
6. AnySoftKeyboard
AnySoftKeyboard is the open-source stalwart with a decade of community-maintained layouts. On foldables it supports a split layout via themes and add-on packs, and every language pack is a separate download so the base app stays small. Fully offline.
Where it falls short: the interface has an old-school Android feel. New users spend time in the settings.
Pricing:
- Free: yes
- Paid: not applicable
Platforms: Android
Download: Google Play | F-Droid
Bottom line: the pick for tinkerers who want an open-source keyboard with active language support.
7. FlorisBoard
FlorisBoard is the newer open-source keyboard aiming for a modern feel. It ships a split layout for wide screens, supports glide typing, and works offline. Development is active and the codebase is public.
Where it falls short: some features are still landing. Prediction quality lags SwiftKey and Gboard while the project matures.
Pricing:
- Free: yes
- Paid: not applicable
Platforms: Android
Download: Google Play | F-Droid
Bottom line: the pick for anyone who wants an open-source keyboard on active development with a real split mode.

FAQ
Does the stock Samsung or OnePlus keyboard work on unfolded foldables?
The Samsung Keyboard and OxygenOS keyboard both offer split modes on unfolded devices, and they work fine. This list is the alternatives for owners who want a different feel or a stronger privacy stance.
Does the keyboard automatically switch when I fold the phone?
Every keyboard on this list respects Android’s screen size changes, so the layout redraws when the fold state changes. Autoswitching to a split layout on unfold is a SwiftKey and Gboard behaviour by default. Others may need a manual toggle.
Are any of these keyboards fully offline?
Simple Keyboard, AnySoftKeyboard, FlorisBoard, and Typewise all process on-device by default. SwiftKey, Gboard, and Fleksy include cloud features that improve prediction; toggle sync off if you want them local-only.
Which keyboard is best for one-hand typing on the outer folded display?
SwiftKey’s collapsible one-hand mode and Fleksy’s adjustable outer layout both suit thumb-only use. Typewise’s honeycomb is surprisingly strong for one-hand typing once the muscle memory clicks.
Do split keyboards work on non-foldable Android tablets?
Yes, most of these ship the same split layout on any tablet-width screen. The difference on a foldable is that the layout switches with the fold state rather than by manual toggle.
