Our verdict
SwiftKey suits people who want a keyboard that learns their typing, with swipe, themes and Copilot built in. The trade-offs: Google Play shows ads, sync relies on a Microsoft account and OneDrive, and the iPhone version allows only two languages at once and lacks some languages the Android version has (Vietnamese, for example).
Best for: People who type mostly English or European languages and want predictions that adapt to them
Skip it if: People who need to type several non-European languages on iPhone: the iOS language list lacks some languages found on Android (Vietnamese, for example), and Microsoft does not say whether Telex or VNI input is offered on Android
Pros
- Strong ratings: 4.6/5 on the US App Store (122,087) and 4.3/5 on Google Play (about 4.6M reviews, 1B+ downloads)
- Learns your writing style, slang and emoji; swipe or tap typing; toolbar with clipboard, GIFs and translator
- Includes Copilot, AI tone rewriting and drafting
Cons
- Google Play shows ads; App Store reviewers mention a Bing toolbar button (the developer says it can be turned off in Settings)
- Sync needs a Microsoft account and runs via OneDrive; iPhone supports only two languages at once
All pros and cons · Who is it for?

Skip it if

Experience & key features
What is SwiftKey?
SwiftKey is a keyboard for Android and iPhone known for learning how you type. The company was founded in 2008, and an Android beta launched in July 2010 with seven languages. Microsoft acquired it for $250 million in February 2016, and since May 2020 the app has been named Microsoft SwiftKey. The iPhone keyboard launched in September 2014 after Apple allowed third-party keyboards in iOS 8. Per Wikipedia, its head office is in London.
Key features
According to the homepage and Google Play, the keyboard corrects spelling, suggests next words, supports swipe (Flow) or tap typing, and has a customizable toolbar with GIFs, clipboard, translator and stickers, plus voice typing. The current version includes Copilot, AI tone rewriting and drafting, and 100+ themes, with your own photo as a background. A cloud clipboard moves text between phone and Windows but requires sign-in.
Price and languages
The app is free. Google Play shows ads; the App Store page lists in-app purchases with themes shown at $0.00. Google Play says the keyboard supports over 700 languages with up to five enabled at once, and Microsoft's page says iPhone supports two. Microsoft's support page includes Vietnamese in the Android language list (700+) but not in the iOS list (600+), and does not say whether Telex or VNI input is offered.
More analysis
Privacy and reliability
Microsoft says data stays on the device if you do not sign up for an account, and sync is optional. The history has two notable points: in July 2016 a sync bug exposed other people's personal details as suggestions; in September 2022 Microsoft announced ending iOS support, removed the app from the App Store on 5 October 2022, then reversed course and relisted it on 18 November 2022 after customer feedback. Both come from Wikipedia.
Versus alternatives
Gboard is the main free comparison, while Laban Key is built for Vietnamese. SwiftKey's strengths are adaptive prediction and Copilot integration. If you type Vietnamese regularly, try the Vietnamese layout on Android first, since Microsoft does not describe it in detail, and the iPhone list does not include Vietnamese.

Privacy
Per Microsoft's privacy Q&A, unless you opt in to a SwiftKey Account on Android, personal and language data stays on the device and is never transferred. With Backup & Sync on, Microsoft's servers process the data; Microsoft says synced data is now stored in a secure folder in your own OneDrive, rolled out in phases and complete by 31 May 2026, and the feature can be turned off. The keyboard does not learn from password fields or remember long numbers such as card numbers, but a password can still be predicted in some cases (for example if you texted it or typed it into a field not flagged as a password). The App Store privacy label (self-declared) lists email and identifiers linked to you plus usage and diagnostics data not linked to you; Google Play says no data is shared with third parties and data is encrypted in transit. In July 2016 a sync bug exposed other people's personal details as suggestions and cloud sync for word suggestions was disabled (per Wikipedia).

Why this score
Good user ratings on both stores (4.6 App Store, 4.3 Google Play). Marked down because some App Store reviewers cite the Bing button and the Full Access requirement for swipe typing.
Why this score
Adaptive prediction, swipe typing, clipboard, GIFs, translator, voice, themes, Copilot and AI rewriting. Marked down for the two-language cap on iPhone and features that need sign-in.
Why this score
Free with no paid tier in the sources reviewed; marked down for ads on Android.
Why this score
The sources reviewed contain no latency or battery figures; the score rests on store ratings that praise autocorrect and predictions, alongside some complaints about auto-correction.
Why this score
Help articles exist on support.microsoft.com, but the sources reviewed show no dedicated direct-support channel for the app.
Why this score
Data stays on the device without an account, and sync is opt-in and now moves to the user's own OneDrive. Marked down for the 2016 sync incident, identifiers linked to you in the App Store label, and passwords that can still be predicted in some cases.
