Short answer: The best third-party iPhone keyboards in 2026 are Gboard for built-in search, Microsoft SwiftKey for swipe and prediction, Grammarly for writing polish, Typewise for privacy and bigger keys, and Voice Keyboard Pro for voice-first dictation with a real mic button, Voice Edit, and translation.
Apple's stock keyboard is fine. It autocorrects, it swipes, it has a tiny dictation mic. But "fine" leaves a lot on the table, and that is exactly why iOS lets you replace it. A third-party keyboard can give you smarter prediction, a privacy model you actually trust, larger keys, grammar fixes as you write, or a serious voice button that does not quit on you halfway through a sentence.
The catch is that the App Store is full of keyboard apps, and most of them are reskins with a theme store bolted on. We cut through it. Below are the third-party iPhone keyboards genuinely worth installing in 2026, grouped by what each one does best, with the honest trade-offs. Availability and features can change, so check the App Store listing before you commit, but the strengths below have held steady for years.
First, how third-party keyboards work on iPhone
Every replacement keyboard on iOS is a "keyboard extension." You install the app, add the keyboard in Settings, and switch to it by long-pressing the globe key in any text field. Two things are worth knowing up front:
- Full Access. Some features (cloud prediction, voice transcription, sync) require you to enable "Allow Full Access." This is a normal permission, but it means you should care who makes the keyboard and what their privacy policy says.
- Secure fields. iOS automatically falls back to the stock keyboard inside password and some payment fields, no matter which keyboard you have installed. That is a security feature, not a bug.
With that out of the way, here is the lineup.
1. Gboard: best all-rounder with search built in
Best for: people who look things up mid-conversation
Google's Gboard is the default recommendation for a reason. It has reliable glide (swipe) typing, solid multilingual support, emoji and GIF search, and its standout trick: a search bar built into the keyboard, so you can look something up and drop the result straight into a chat without leaving the app. It also includes a voice dictation button.
Strengths: mature swipe typing, huge language coverage, in-keyboard search, frequent updates.
Trade-offs: it is a Google product, so privacy-conscious users should read the policy and decide how they feel about Full Access. The voice button is a quick afterthought rather than a serious dictation tool, and it inherits the same short-listening behavior as most built-in mics.
2. Microsoft SwiftKey: best swipe and prediction
Best for: heavy swipe typists who want sharp next-word prediction
SwiftKey built its reputation on prediction, and it is still among the best at guessing your next word and adapting to your style over time. Swipe input is excellent, it supports many languages at once, and it offers deep theme customization. Microsoft has kept it well maintained.
Strengths: top-tier prediction and swipe, multilingual typing without manual switching, mature and stable.
Trade-offs: like Gboard, it leans on cloud features that want Full Access. And like Gboard, voice is a minor feature, not the point.
3. Grammarly Keyboard: best for writing polish
Best for: emails, work messages, and anything where tone and correctness matter
If your problem is not speed but quality, Grammarly's keyboard checks spelling, grammar, and clarity inline as you type, and flags awkward phrasing. For people who fire off important messages from their phone, it is a genuine confidence boost.
Strengths: real-time writing suggestions, tone hints, strong for professional communication.
Trade-offs: the most useful suggestions sit behind a subscription, it requires Full Access to analyze your text, and it is built for correction rather than fast input. It does not meaningfully speed up getting words onto the screen.
4. Typewise: best for privacy and bigger keys
Best for: people who mis-tap a lot or want on-device privacy
Typewise takes a different physical approach with larger, honeycomb-style keys designed to reduce typos, and it emphasizes on-device processing for privacy. If you find the standard QWERTY grid cramped, the bigger targets can genuinely cut your error rate.
Strengths: larger keys that reduce mis-taps, privacy-forward design, autocorrect that adapts.
Trade-offs: the unusual layout has a learning curve, and not everyone sticks with the hexagonal grid. Voice is not its focus.
5. Fleksy: best for speed and extensions
Best for: typists who want a fast, customizable keyboard with add-ons
Fleksy has long been known for fast input, gesture controls, and a system of extensions that bolt extra tools onto the keyboard. If you like tinkering and want gestures for cursor control and deletion, it is worth a look.
Strengths: quick input, gesture shortcuts, customization and extensions.
Trade-offs: feature set and availability have shifted over the years, so confirm the current App Store version meets your needs before relying on it.
6. Voice Keyboard Pro: best for voice-first dictation
Best for: anyone who would rather talk than thumb-type
The five keyboards above are all built around tapping or swiping, with voice as a small extra. Voice Keyboard Pro flips that. It is a custom iPhone keyboard with a large, central microphone button as the main event. You tap it once, speak as long as you like, and your words appear in any app, from Messages and Mail to Safari, Notion, and your bank's app. Crucially, it does not cut you off after a short pause the way Apple's stock mic tends to, so a full thought actually makes it onto the screen.
What makes it more than a dictation button:
- Voice Edit. Speak a correction, such as "change Tuesday to Thursday," and the text updates in place. You fix mistakes by voice instead of dropping back to the keyboard.
- Two-way translation while you dictate, across 24 languages. Speak in one language and have the text appear in another, which is rare among keyboards.
- Swipe typing too, so on the occasions you do want to type by hand, you are not giving anything up. We cover how the two pair in our piece on combining swipe typing with voice dictation.
- A privacy model built for trust. The app sends no audio or transcript content to its servers, only operational pings. Your words stay yours.
The dictation itself runs on Voice Keyboard Pro's advanced transcription engine, which is what lets it stay accurate across accents and real-world noise while keeping latency low. If voice is your priority, it is the obvious pick. For a deeper head-to-head, see our roundup of the best voice keyboard for iPhone.
How to choose
Match the keyboard to how you actually communicate on your phone:
- You swipe and look things up constantly: Gboard.
- You want the sharpest prediction for fast thumb typing: Microsoft SwiftKey.
- You send important messages and want them polished: Grammarly Keyboard.
- You mis-tap a lot or want on-device privacy: Typewise.
- You want speed, gestures, and extensions: Fleksy.
- You would rather talk than type, or your hands need a break: Voice Keyboard Pro.
Nothing stops you from installing several and switching with the globe key based on the moment. Many people keep a swipe keyboard for quick taps and a voice keyboard for longer messages. If you are still on the stock keyboard's dictation, our explainer on Voice Keyboard Pro vs Apple dictation shows exactly what changes when you switch.
A note on the speed nobody talks about
Here is the thing the swipe-versus-tap debate misses. The average adult types around 40 words per minute on a full keyboard, and noticeably slower with thumbs on glass. Even a fast mobile typist tops out well below conversational speech, which runs 130 to 150 words per minute for most people. No amount of prediction or swipe optimization closes that gap, because the bottleneck is your fingers, not the software guessing your next word.
Voice does close it. That is why, for getting words out of your head and into a text field, a voice-first keyboard is not just another option in the list. It is a different category of speed. The other keyboards make tapping a little better. A voice keyboard removes most of the tapping.
The best swipe keyboard makes you a faster typist. A voice keyboard makes typing optional.
What to watch out for before you install
Replacing the stock keyboard is low-risk, but a few things separate a keyboard worth keeping from one you uninstall in a week:
- Privacy and Full Access. A keyboard with Full Access can, in principle, see what you type. That is not inherently sinister, it is how cloud features work, but it means you should only grant it to apps from developers whose privacy policy you trust. Look for a clear statement about what leaves your device. Voice Keyboard Pro, for example, sends no audio or transcript content to its servers, only operational pings.
- Lag and battery. A heavy keyboard that hesitates between keystrokes is worse than the stock one no matter how many features it has. Test responsiveness in a fast chat before you decide. Well-built keyboards add no perceptible drain.
- Abandoned apps. The App Store still lists keyboards that have not been updated in years. An out-of-date keyboard can break with new iOS releases. Check the "last updated" date before installing.
- Secure fields. Remember that iOS forces the stock keyboard inside password and some payment fields. No third-party keyboard, voice or otherwise, will appear there. That is by design and a good thing.
- Themes are not features. Many keyboards lead with hundreds of themes and fonts. Looks are nice, but they do not make you faster or more accurate. Judge a keyboard on input quality first.
Frequently asked questions
Are third-party keyboards safe on iPhone?
Yes, when they come from reputable developers. iOS sandboxes keyboards, requires explicit permission for Full Access, and blocks all third-party keyboards inside secure fields like passwords. The main thing to check is the developer's privacy policy and whether the app is actively maintained.
Can I have more than one keyboard installed?
Absolutely, and most power users do. Add as many as you like in Settings, then long-press the globe key to switch between them in any text field. A common setup is one swipe keyboard for quick taps and a voice keyboard for longer messages.
Do third-party keyboards work in every app?
In almost every app, yes. The exception is secure input fields (passwords, some payment screens), where iOS automatically swaps in the stock keyboard for security. Everywhere else, from Messages and Mail to Safari, Notion, and most banking apps, your chosen keyboard works.
Which third-party keyboard is best for privacy?
Typewise emphasizes on-device processing, and Voice Keyboard Pro keeps your audio and transcripts off its servers, sending only operational pings. Both are stronger privacy stories than keyboards built around cloud prediction and search. Always read the current policy to confirm.
What is the fastest way to type on iPhone?
Speech. Conversational speech runs 130 to 150 words per minute, while even fast thumb typing falls well short. A voice-first keyboard like Voice Keyboard Pro is the fastest path to getting text onto the screen, especially for longer messages.
The bottom line
There is no single "best" iPhone keyboard, only the best one for how you work. Gboard and SwiftKey remain the strongest all-rounders for tapping and swiping. Grammarly is the pick for polish, Typewise for comfort and privacy, Fleksy for tinkerers. And if you would rather speak than type, Voice Keyboard Pro is the one built voice-first, with a real mic button, voice correction, and translation, in every app.
Voice Keyboard Pro has a free tier with daily limits, so you can install it in about a minute and see whether talking beats typing for you. Pro is $4.99 per month or $34.99 per year. Try it on your next long message and watch how much faster the words land.
