Must Have List: Top 10

There has been a lot of thought that went into the UI/UX of S3. I love the universal setup across all my devices and not having to worry that an rclone mount/unmount is gonna force a reboot. The dev has achieved a great balance of both form and function. This sets a new bar for how iOS apps should be done.

Very satisfied

I use this app to backup the contents of my phone to AWS S3 since I find S3 to be much more reliable and fast than other cloud drives like Onedrive. This app works really well, is smooth and very intuitive to use. Also the developer is very quick to address any bugs and adds support for new S3 features quickly too. Highly recommended for people who are a bit technically savvy.

PERFECT!!

Do everything that promisses… Perfect for tests and even backup from mobile phones

Works perfect!

Each time I use it simplifies what I need to do. Upgrades only keeps making it better!!!

MMM

Fret

Simply Fantastic

I've been looking for a long for an app that exposes a File Provider for Backblaze B2 and this one is the best. It has handles the best edge cases, retries and other quirks of other object storage I haven't seen other apps do. I have an app that writes very heavily to B2 and this one is the only that has exposed a file provider that can keep up.

Great functionality

This has been perfect for my particular use cases, which are around S3 access and visibility. I’ve been able to use this tool to sort out connectivity challenges with other apps.

Not useful

Not intuitive, difficult to setup and to use.

Perfection

This app is so much better than I expected it to be - I’ve tried other apps for doing this in the past and the experience was always rather janky and unreliable, but this is simply perfection.

就写了两字要钱

一般般,不好用,还不如网页端

感谢您的反馈!主要优势在于,您的 S3 对象会显示在"文件"App 中,所有 App 都可以访问这些文件。其实您可以免费使用单个 S3 配置,无需付费。

RPrice

A great S3 application that just works to upload & download large (200GB+) & small (10-50GB) files to AWS. The only limitation is the sizing of the system drive where S3 is being used.

So helpful and just works

In about 6-months I’ve never had an issue with S3 Client. I use it for backing up and file restoration — connecting my Mac to my S3 instance. Superb work! Thank you

Amazing Utility

Being able to store and access S3 buckets from Shortcuts is a game changer for me. Saves me tons of time, and allowed me to fully automate some processes I had never been able to before. Thank you!

Anonymous key identification

Support the project team. I cannot connected to the wasabisys public dataset by anonymous configuration. How to connect it?

Super helpful !

It’s clean and very intuitive. We love using it here at our office to upload files directly to s3 without having to login every few hours on the s3 console

Great

I do like this app and I would like the same but for WebDAV servers ^w^

Subscribe or live with minimal / no features?

I’m not sure why the store description mentions “Free for one server, Pro unlock required for multiple servers” when it really wants to say “Free for one server missing most features but we will prompt you right at the first start to tell you that the majority of usability is locked behind pro but you get 7days trial!”. If a subscription is required for actions as basic as “delete a file” then say so upfront.

New users are able to fully access and delete from a single server without paying if they first downloaded S3 Files v2026.11 or later. The App Store description should accurately describe what new users can do. Non-playing users that first downloaded earlier versions of the app are able to have unlimited numbers of servers but can only browse these. At one point the App Store description was different to accurately describe these conditions. If you first downloaded S3 Files after the release of 2026.11 on February 19 then please contact me at anders@s3files.app as something must be misbehaving. If you are a recent new user and should have full access to one server for free, try updating to version 2026.18 that has a bug fix in this regard.

Potentially dangerous

I bought this app having moved over from Windows. I needed a client to easily access S3 storage as sometimes I need to upload files.

At first it was working as intended, however this past week I noticed that files in our cloud storage were randomly being renamed. Something was adding numbers onto the end of filenames, like “2 “, “ 3”.

Even after upgrading security on the bucket it was still happening. Then yesterday I noticed that my CPU usage was through the roof, and upon checking processes I noticed that this app was using tons of CPU. I killed the process, but it started back up again. I eventually killed it and uninstalled the app. Since then I’ve had no more incidents of files being renamed.

I suspect this app is doing something dangerous, or has a bug which causes problems. Do not download!
