01iOS · iPadOS

What is KMate Mobile, and who is it for?

KMate Mobile is the iPhone and iPad edition of KMate. It is built for reviewing Kindle notes and vocabulary in short moments, but it is not only a viewer: you can import from the Kindle app or Amazon Cloud, edit notes, use flashcards, view statistics and export directly on your device.

02KMate Mobile

Can I use KMate Mobile without the desktop app?

Yes. KMate Mobile works independently on iPhone and iPad. You can import from the Kindle app and Amazon Kindle Cloud, browse and edit your library, review with flashcards, view statistics and export.

03iCloud

How does Mac and iOS sync work?

KMate for Mac and KMate Mobile can sync notes, highlights, vocabulary, definitions, tags and learning progress through your personal iCloud account. Your data stays in your Apple account rather than a KMate-operated cloud service. iCloud sync requires KMate Pro on Mac and is free in KMate Mobile.

04Windows · iOS

Can Windows sync with KMate Mobile?

Windows does not use the Mac-to-iOS iCloud sync path. KMate Mobile can import a KMate Windows database so you can carry notes and vocabulary to iPhone or iPad. Treat this as a database handoff, not continuous two-way iCloud sync.

FAQ

Help Center - FAQ

Why can't KMate connect to my Kindle?

For classic models (Touch/Voyage/Oasis/Paperwhite pre-2022), use a USB cable that supports data transfer (not charge-only). For newer models (2022+ Paperwhite/Colorsoft/Scribe), they use MTP protocol — ensure no other MTP apps (like Android File Transfer) are running. On Mac, you may need to grant disk access permission when first connecting.

Why are some notes missing after import, or some books not showing up?

KMate can only import notes that actually exist and are readable in the selected source. Notes visible inside a Kindle book may not all be included in the import file or cloud Notebook. Each source has a different scope and limitations:

  • Kindle device (My Clippings.txt)

    This usually records highlights and text notes created on that Kindle. It does not fully consolidate notes created on other devices or in the Kindle app. Some books also have clipping limits. Once the limit is reached, the file may contain only a limit notice instead of the full highlighted text.

  • Kindle app (exported HTML file)

    For books purchased from Amazon and personal documents added to your cloud library through Send to Kindle, sync under the same account, then export notes from a Kindle app that supports export and import them into KMate. Books opened only locally in the app usually include only notes from that device. Exported content from some books is also subject to percentage limits; check the actual export notice.

  • Amazon Kindle Cloud Notebook (web notes)

    This primarily provides synced highlights and notes from books purchased from Amazon. Send to Kindle personal documents usually do not appear here, even when they sync between devices and apps. Local books transferred over USB are also outside this source’s scope.

Recent firmware issue: Multiple users have reported that Kindle firmware versions including 5.19.6 may fail to write new highlights or notes to My Clippings.txt, even though they remain visible inside the book. If you recently updated your Kindle, check the firmware version and whether the file contains your latest notes.

KMate for Mac Pro removes the free edition’s 1,000-note display limit, but cannot recover content missing from the source. You can try another available import source. If notes are present in the source but do not appear in KMate, contact us with your import method, Kindle model, and firmware version so we can help investigate.

What is KMate, and how is it different from other tools?

KMate is the cross-platform successor to Kindle Mate, building on more than ten years of Kindle library management. It imports highlights, notes and vocabulary from Kindle devices, the Kindle app and Amazon Cloud; on Mac, it also imports Apple Books highlights and notes. Then you can organize, search, read, review and export them in one local-first library. Reading Mode, tags, colors and learning or reading status help you keep working with the material after import. Desktop data stays on your device; KMate for Mac and KMate Mobile can also sync through your personal iCloud account. iCloud sync requires KMate Pro on Mac and is free in KMate Mobile.

What is the difference between the Mac and Windows versions of KMate?

In terms of release cadence: since version 3.5.33, Mac and Windows have used synchronized dual-platform releases. Store review processes can still make listing availability differ slightly. The core workflow is aligned across both platforms: import, library organization, dictionaries, Reading Mode, and export. There are a few platform-specific capabilities. macOS can import Apple Books highlights and notes, and its sandbox may require a one-time authorization for a classic Kindle or external dictionaries. Windows automatically detects Kindle models and connection status, and handles its mobile workflow by handing a KMate database to KMate Mobile rather than Mac–iOS iCloud sync. iCloud sync requires KMate Pro on Mac and is free in KMate Mobile.

Can I sync without a Kindle device?

Yes. Import from Amazon Kindle Cloud (for purchased books) or HTML notes exported from the Kindle App. On Mac, you can also import highlights and notes directly from Apple Books.

What dictionary formats are supported?

Desktop supports StarDict (.tar.gz), Mdict (.mdx), MOBI/PRC, three-column TSV, and plain-text dictionaries. KMate Mobile can import MDX/MDD, StarDict, MOBI/AZW/PRC, and text dictionaries directly on iPhone and iPad. Online definitions include Google Translate, Bing Translate, Gemini AI, and DeepSeek AI.

How do Free and Pro differ across Mac, Windows and iOS?

Because the platform and release model differ, KMate uses different Free/Pro strategies. Mac App Store: The free Mac edition has no time limit and supports import, organization, dictionaries and export for your 1,000 most recent imported items. KMate Pro unlocks unlimited capacity and iCloud sync through a one-time purchase or subscription. Microsoft Store (Windows): the download is the Pro edition with all features and unlimited capacity, plus a 15-day free trial. There is no subscription; a one-time purchase unlocks lifetime access. iPhone and iPad: the free edition includes Kindle/Amazon import, unlimited browsing and flashcards, TXT export and Anki export. Pro adds advanced themes and fonts, Markdown/PDF export, printing and unlimited Stats & Insights. Pro adds double-tap word lookup and Kindle My Clippings.txt export. iCloud sync requires KMate Pro on Mac and is free in KMate Mobile.

What are the system requirements?

KMate supports macOS 10.13 or later, Windows 10/11, and iOS/iPadOS 17.0 or later. The Mac edition supports both Intel and Apple Silicon.

Which Kindle devices are supported?

KMate supports ALL Kindle models including the latest Kindle Paperwhite, Kindle Colorsoft, and Kindle Scribe series, as well as all classic models like Kindle Touch, Voyage, and Oasis.

Does KMate upload my data?

No. Your library is stored locally by default. iCloud sync uses your personal Apple account; Amazon import reads only the Kindle data you request; and online dictionary features send only the word or phrase being looked up. iCloud sync requires KMate Pro on Mac and is free in KMate Mobile.
