Coolmuster iOS Assistant: Copy, Back Up and Manage iPhone Data on a Windows PC
Coolmuster iOS Assistant is a $25.95-a-year Windows program that copies contacts, messages, photos, videos, music and other data from an iPhone, iPad or iPod touch to your PC, puts some of it back, and makes and restores full backups. A lifetime license is $35.95. It's for iPhone owners on Windows who find iTunes awkward and want readable copies of their data, such as a contacts spreadsheet or a saved text conversation, on their own computer. It was called Coolmuster iPad iPhone iPod to Computer Transfer in earlier versions.

- What we checked: we downloaded the 34.8 MB Windows installer from coolmuster.com and matched its date to the vendor's release notes for version 4.6.38, and confirmed the order page charges $25.95 for the 1-year, 1-PC license with a 12-month renewal on November 8, 2026. We didn't connect an iPhone or run a backup.
Before you buy: what it won't copy
Coolmuster iOS Assistant doesn't export MMS messages, call logs, audiobooks, note attachments, photo metadata, or app data such as WhatsApp and LINE chats, according to Coolmuster's own FAQ. Exported text messages can also come out named by phone number instead of contact name, an issue the FAQ says is still being worked on. If saving iMessage photos or WhatsApp history is your goal, this isn't the right tool.
The trial lets you export one file at a time, 15 times. That's enough to check that your iPhone connects and that the messages and photos you care about show up, so try it before you pay.

Overview
iOS Assistant reads your device over a USB cable and lays it out like a file manager. The left side lists Contacts, Messages, Notes, Calendars, Bookmarks, Music, Videos, Photos, Books and Apps. Pick one, tick items, and Export copies them to a folder on your PC. For contacts, calendars, bookmarks and books, Import goes the other way.
The Super Toolkit tab handles whole-device backups. You can back up to the folder iTunes normally uses or to any folder you choose, restore a backup to a device, add old backups from elsewhere and delete the ones you no longer need. Everything stays on your PC, with no iCloud storage involved.
The Summary screen after connecting: model, iOS version, battery and a storage breakdown. The vendor's screenshots show an older iOS version.
Features
Save text messages and contacts to your PC
Coolmuster iOS Assistant lists your message threads with dates and a preview, and exports them to your computer. Contacts export as CSV, VCF or XML files, and you can add, edit and delete contacts on the iPhone from the PC.
Messages: tick the threads you want and click Export.
Move photos, videos and music off the iPhone
Coolmuster iOS Assistant shows photos and albums with name, size, format and date, and marks which ones are only in iCloud. It exports photos, videos and music at their original quality, and can delete them from the device to free space. Version 4.6.38 added exporting Live Photos.
Photos: each file shows its format and whether it's on the device or only in iCloud.
Back up and restore without iTunes' interface
Coolmuster iOS Assistant's iTunes Backup Management makes a full backup to iTunes' default location or a folder you pick, which helps when your C: drive is short on space. Restore writes a selected backup to a connected device, and you can import or delete backups from the same list.
Backup: choose the device, then the default iTunes folder or your own.
Restore: pick a backup by date, size and iOS version.
Calendars, bookmarks, books and apps
Coolmuster iOS Assistant also exports and imports calendars, Safari bookmarks and books from the Books app, and uninstalls apps in bulk. Books bought with copy protection (DRM) won't open after export, and books from Kindle or other reading apps aren't included.
Benefits
- Readable copies. A contacts CSV opens in Excel and a message export opens on any PC, which an iTunes backup file doesn't give you.
- Your storage, not iCloud's. Big photo and video libraries move to your own drive without a paid iCloud plan.
- Choose what moves. You pick single items instead of syncing everything.
Real-World Uses
- Freeing up a full iPhone. Export years of photos and videos to the PC, check them, then delete them from the phone.
- Keeping a conversation. Save a text thread with a landlord, employer or family member to your PC as a record.
- Contacts into a spreadsheet. Export contacts to CSV for a mailing list or to tidy them up in Excel.
- Backing up before an iOS update or repair, to a folder on a second drive instead of a crowded C: drive.
Who It's For, and Who Should Skip It
It suits Windows users with an iPhone or iPad who want to copy their own data to the PC in usable files, without learning iTunes.
Skip it if you need WhatsApp, LINE or MMS photos saved (it doesn't read app data or MMS), or if you want to copy straight from one phone to another, which needs a separate tool such as Coolmuster Mobile Transfer. If you only need photos off the phone, Windows' own Photos app or File Explorer already imports them for free. Android owners need Coolmuster Android Assistant instead.
Usage Guide
- Make sure iTunes (or Apple's device software) is installed and recognizes your iPhone, since iOS Assistant needs it to detect the device.
- Download the installer from the Download Free Trial button, install and launch Coolmuster iOS Assistant.
- Connect the iPhone with a USB cable, unlock it and tap Trust on the "Trust This Computer?" prompt, then click Continue on the PC.
- Choose a data type on the left, tick items and click Export, or click Import to add files from the PC.
- For a full backup, open Super Toolkit, choose the iTunes backup tool, click Backup, choose the location and click OK.
- To register, click the key icon and enter the licensed email and code from your order email.
Where it falls short
- Several data types are missing. No MMS, call logs, audiobooks, photo metadata or app data, as listed above.
- Known problems in the FAQ. Messages may not load when the iTunes backup is encrypted (remove the password first), photos and videos may fail to load or export when iCloud is involved, and exported messages may be named by number rather than contact.
- No direct device-to-device copy. Moving music or movies from one iPhone to another means exporting to the PC and syncing again through iTunes.
- Old-fashioned look. FileHorse's reviewer called it "more towards functional than flashy", and the vendor's own screenshots still show older iPhones.
- Subscription by default. The $25.95 license renews every year unless you cancel, and Coolmuster's refund FAQ says renewal charges are generally non-refundable.
What Users Say
We found no in-depth magazine test of iOS Assistant. The feedback below comes from a download site's editor review, Trustpilot reviews that mention it or iPhone transfers, and the vendor's own testimonials. Product Hunt's page for the Mac version has no reviews.
FileHorse: editor review by Marian Marinescu (users 8.6/10 from 12 votes)
On the interface: "The UI of this software is clean, intuitive, and user-friendly." But "it lacks some modern flair; it leans more towards functional than flashy."
The verdict: "Coolmuster iOS Assistant is a solid option for users seeking a reliable and straightforward way" to manage iOS data, "While it may lack some of the bells and whistles of more expensive alternatives."
And a warning about the trial: "Only one item can be transferred to the PC at a time. Limited functionality in the demo version."
Trustpilot: 4.6 from 222 reviews (all Coolmuster products)
The score covers the whole company, and most reviews are about quick support. Those about iPhones are mixed:
- Andrew, 5 stars, May 2025: "Coolmuster is a very useful and inexpensive program that I use to transfer my iphone pictures."
- Patricia Turner, 5 stars, April 2025: "The 1st time I ordered IOS assistant I ended up with a 1 year (1 PC) license instead of a Lifetime licence." Her review is titled "Excellent service", but check which license is in your cart.
- Jim Hocut, 1 star, March 2024, titled "Buyer Beware.... useless product", about an Apple tablet: "it will only go from the Apple to PC." (Coolmuster's reply pointed to iOS Assistant.)
- Gregory Montoya, 1 star, July 2024: "I backed up my iPod touch 4 gen with Coolmuster, only to have it restore it with 31.9 gb of no data!"
Coolmuster's website: 4.6 from 235 reviews (vendor's own figure)
These are shown on the vendor's site, so treat them as a friendly sample:
- "It is a great and easy tool to back up contacts, photos, videos,etc. to iTunes, computer...So nice to have it." Nina
- "I wanted to back up four years of iOS messages. Coolmuster did this like a breeze. I wasn't required to several pages of information." Ron Harris
- "With it, I can bulk transfer any files from phone to the computer very fast. Also, I can upload files from the computer to my device within simple clicks." Rebecca
The pattern: people like how simple it is to get photos, contacts and messages onto a PC. The complaints are about what it can't do (copying to the device, restores that went wrong on old hardware) and a trial too small to judge a big job. Use the trial to confirm your device connects and your data shows up, and keep a second backup of anything irreplaceable.
Comparisons
Coolmuster iOS Assistant vs iTunes or Apple Devices
Apple's free software makes full backups and syncs media, but it gives you no readable copies of individual messages or a contacts spreadsheet, and it always backs up to the system drive. iOS Assistant adds item-by-item export and a choice of backup folder. Both are local backups, and many people will keep using Apple's alongside it.
Coolmuster iOS Assistant vs Coolmuster Mobile Transfer
iOS Assistant copies between an iPhone and your PC. Mobile Transfer copies directly between two phones, iPhone or Android. If you're switching phones, Mobile Transfer is the one to look at.
Windows version vs Mac version
Coolmuster sells a separate Mac version (5.1.47, December 2025) at the same prices. On November 8, 2026 the Windows version was the more recently updated of the two.
Editions and Pricing
All plans have the same features and free updates while the license is valid. Prices are for the Windows version and exclude VAT.

Larger Business licenses go up to 26-30 computers ($185.95 a year or $245.95 lifetime). The Buy Now buttons on this page open the 1-year, 1-PC license. If you'll use it for more than a year, the lifetime license is only $10 more.
FAQs
Does Coolmuster iOS Assistant work with the iPhone 18 and iOS 27?
Coolmuster iOS Assistant lists iOS 5 and later, including iOS 27 and the iPhone 18 series, and iPads and iPod touch models too. Your PC also needs iTunes or Apple's device software able to recognize the device.
Does Coolmuster iOS Assistant need iTunes installed?
Coolmuster iOS Assistant doesn't use iTunes' interface, but Coolmuster's guide says the device must be detected by iTunes (or Apple's Music app), so keep Apple's software installed and up to date on the PC.
Can Coolmuster iOS Assistant save WhatsApp chats or iMessage photos?
No. Coolmuster iOS Assistant doesn't export app data such as WhatsApp or LINE, or MMS messages.
Can Coolmuster iOS Assistant work over Wi-Fi?

What happens when the Coolmuster iOS Assistant 1-year license ends?
The 1-year license renews automatically through the 2Checkout order system unless you cancel it, and you get a reminder email 7 days before. Coolmuster says renewal charges are generally non-refundable, so cancel first if you don't want another year.

Conclusion
Coolmuster iOS Assistant is worth $25.95 a year, or better $35.95 once, if you're on Windows and want your iPhone's photos, contacts and texts on your PC as files you can open, plus backups in a folder you choose. The reason to buy it is that it makes those exports a few clicks instead of an iTunes chore. The reason not to is the list of things it leaves out: MMS, call logs, app data like WhatsApp, and any direct phone-to-phone copy. Test it with the free trial on your own iPhone first.
