### 3/5 — It’s functional. Sometimes

*2026-06-20, version 5.2.0*

I find this app (and its permutations on other various platforms and the web interface) to be cumbersome and not very intuitive. It is functional, except uploading from my iOS device seems to frequently time out for large files. I’d would not pay for storage, but as a freebie for my VPN service it serves its purpose.

### 2/5 — File backups

*2026-02-06, version 5.2.0*

It appears that not all files and folders from computer file and iPad updates that are within others folders that are by accounts on the web app are up to date according to the sync app.

### 3/5 — Use to work great but lots of glitches now.

*2024-12-04, version 5.2.0*

I’ve used SugarSync for 10 years but the last year it has continued to crash and not sync. I’ve had to uninstall and reinstall repeatedly, which takes hours and two weeks later it stops syncing again.

### 3/5 — I wish I wasn’t writing this

*2024-04-28, version 5.2.0*

I’ve supported this app for many many years. 10+? But I find I’m always making excuses for it when it doesn’t work. I originally loved the flexibility of being able to assign any folder to the cloud. But, It’s not seemless. The app is constantly going offline, requiring me to manually reset it. And it hangs when I use it to grab files in Procreate. I don’t want to have to think about this tool. I just want to proceed with my work.

### 2/5 — Was great, then good, now lousy

*2024-01-17, version 5.2.0*

The entire experience has gone downhill.  From zippy file syncs to slow and laggy experience.

### 4/5 — Good core, frustrating details

*2023-08-23, version 5.2.0*

Sugar sync offers a core feature no other syncing service does; the ability to sync arbitrary folders on your computer rather than a specific special one. This is why I put up with the higher than usual price per GB of storage, and the frustrating bugs and lack of polish in especially the iOS apps.
Of particular note is how poorly the integration into the Files app works, which routinely fails to load the content of folders that load fine in the sugar sync app. 
In conclusion, I continue to use sugar sync primarily because my subscription is locked in at a lower price from many years ago, and the unique feature set might not be worth it were I considering it at full price today.

### 5/5 — Issue with photos

*2023-04-05, version 5.2.0*

Not all of my photos in my iPhone will load to SugarSync. I have to manually select the missing photos and send them to SugarSync.

### 2/5 — App has been broken for a long time

*2023-01-28, version 5.2.0*

I’ve been a paid SugarSync user for many years. The desktop/web stuff mostly works well, but the IOS app has always been a disaster.

- The app constantly crashes.
- You can’t easily download a file from the app to the phone storage to be able to open it in a 3rd party app
- trying to access SugarSync files from within the IOS Files integration never works, it just shows empty folders.

I really want to move away from SugarSync but it’s the only sync app which lets you pick any folder from a windows machine to synchronise, rather than have its own folder like OneDrive or Magic Briefcase!

### 1/5 — Problème de connexion sur iPhone

*2022-09-06, version 5.2.0*

Dommage mais depuis quelques temps, impossible de l’utiliser sur iPhone : ferme systématiquement au bout de quelques secondes : une mise à jour s’impose pour retrouver ses étoiles

### 1/5 — Mobile APP Crashes constantly

*2022-09-02, version 5.2.0*

Been trying to get it resolved for 2 weeks!!!!! DropBox doesn’t crash so might be moving everything to DropBox SugarSync is useless if my iPhone doesn’t connect to my files.  Been crashing since June 2022 and no one in tech support has helped me.  

I can’t depend on the files to be available to me on my iPhone.  

Unacceptable.

### 1/5 — AVOID

*2026-05-20, version 5.2.0*

They deleted all my data. They admitted their emails often go to spam so it’s not surprising I didn’t get the warning. This is not a reliable company I would not trust them with your data.

### 1/5 — App crashes zero support

*2026-03-31, version 5.2.0*

Are they even a company anymore or just taking our money?  App does not work zero return calls or emails from support. Used to be good now I would stay far far away.

### 1/5 — いろいろとダメなサービス

*2026-02-01, version 5.2.0*

古参のクラウドストレージサービスだがアプリの作り込みが甘い。まず、転送画面がメインメニューに戻らないと見られない、フォルダ丸ごとのアップロードができない。転送画面で、ファイル容量がわからず、転送速度も残り時間やパーセントの表示もない。1ファイルで約6Mb/sの転送速度はまあまあだが同時並行転送ができないのでトータルでの転送速度が速くならない。アプリがバックグラウンドになってから戻るとそのことを認識はするのにファイル転送が中断されてしまい、再開操作ができない。アップロード先のフォルダに存在するファイルを転送しようとすると全て上書きされる。(普通は上書きするかをユーザーに質問した上で、同じファイルは転送から除外できるもんだと思う。) 転送が終わると転送リストが勝手に消去される(消去ボタンの意味かない)。サーバー自体は軽いのにアプリがいまいちで契約を続ける気になれない。惜しいサービスだ。WebDavもサポートされてない。値上げされるとメールが来たので解約申請したが請求が止まらずカスタマーサポートに依頼してようやく請求が止められた。何から何までレベルが低い。

### 1/5 — Is sugarcsync support out there????

*2025-03-25, version 5.2.0*

I have sent in 3 emails. No response. App crashing non stop.  Anyone out there? Anyone care? How do i get tech support if you don't answer phones or emails. Ps. - ten year customer here.

### 1/5 — ???

*2025-03-10, version 5.2.0*

Impossible de s’inscrire

### 1/5 — Getting worse..

*2024-08-10, version 5.2.0*

Used to be a great app, now slow sync and login issues. Paid for a year, waste of money. Can’t even contact support, says my password is wrong, it’s not! Refund please

### 1/5 — Syncs with desktop, but not iPhone

*2023-09-26, version 5.2.0*

Have had this app for 10+ years and use it primarily for desktop cloud backup. That part works and files are synced and current, although iPhone problem doesn’t give me an overall “warm and fuzzy.”  

Used to be able to access and download current desktop files to older iPhone SE. Now seems “frozen in time” when trying same with 2-year old iPhone 12 Mini. Desktop files showing available to the phone are 2+ years old, not the current ones. Suggestions from tech support 1 or 2 years ago did not solve the issue. It doesn’t have to be this hard. Will likely be looking for another option one of these days.

### 1/5 — Unable to login for 3 weeks

*2022-11-02, version 5.2.0*

I have been unable to login for 3 weeks. One week ago they announced this problem is resolved but I am still unable to login. I have contacted their support every day for a week asking for help and not received a single response but they have taken my monthly subscription fee.

### 1/5 — Two weeks with no access

*2022-10-23, version 5.2.0*

Sugar sync recently had a major malfunction. Most accounts were inaccessible for two weeks. That’s right two weeks. If it was a couple hours or even a day I would understand, but they couldn’t get it resolved for over two weeks? It’s absolutely ridiculous. I’ve been a sugar sync customer for several years now, but that is unacceptable and I’m switching to something else. I would not recommend them.

### 1/5 — Assistant zéro

*2022-10-08, version 5.2.0*

Impossible qu il me permettent de passer a un abonnement de orange qui existe plus a un abonnement avec le même mail Et en plus il répondent en anglais et ils comprennent rien à notre demande

### 5/5 — Well seems the IOS app doesn't back up files right?

*2026-05-21, version 5.2.0*

Maybe im not understanding the back up process? It keeps running out background processing time?

### 5/5 — Long time user!

*2025-08-22, version 5.2.0*

I can’t even remember when I first started using Sugar Sync, but it was probably 2009 or 2010. That’s a lot of years! It’s always been a safety net-especially for those precious files I don’t want to lose. Definitely worth it, in my opinion!

### 5/5 — I love Sugarsync

*2025-06-21, version 5.2.0*

I use Sugarsync constantly to link two laptops and one desktop. It provides seamless syncing of all my work files. I can jump from one computer to another without worrying if I have the most recent version of a file (it is always there). I like the security features (two step verification) and the ability to go back to archival files. Sugarsync is an awesome service.

### 5/5 — 5 stars because unlimited name of the folders in sugarsynch servers.

*2025-03-01, version 5.2.0*

Best and fast free , barter ilmu with my downloads and free from your free trials server from your clouds, freetrials maybe only 2025, not only $$$(thank)

### 5/5 — Great app!

*2024-12-18, version 5.2.0*

It’s great because it can still sync between my iOS 18 device and my iOS 5 devices. Please keep the servers up for legacy devices for years to come! Thank you.

### 5/5 — Peu mieux faire

*2024-10-30, version 5.2.0*

C est mieux qu avant mais commet supprimer les activités récentes ?

### 5/5 — works great on my iPhone 11 syncing to my Windows laptop

*2024-09-11, version 5.2.0*

after figuring out how to configure things and use the app properly, I found it to be very convenient. It works well and all functions work as designed.

### 5/5 — Functional for the most part...

*2023-12-17, version 5.2.0*

The issues with this app appear to not be the application itself but the extreme limitations placed upon it by IOS. It is seemingly quick and doesn't freeze for the most part. However, on the Android OS there are NO issues whatsoever. I've been using this amongst a multitude of other clouds on both platforms for years now and have never problems unless on IOS or iPad OS. It is truly wrong to be held responsible by customers for problems that have nothing to do with you.

### 5/5 — New version is great!

*2023-08-24, version 5.2.0*

I nearly quit last year. 
Fortunately my Mac and Windows and IPhone and IPad sync files automatically now!
Just as promised. 
Thanks folks for your work.
