## What is S3 Client?

Access your S3 storage directly from the Files app, Finder, and other applications on iPhone, iPad, and Mac. Developed by the creator of Working Copy, this application provides seamless integration with S3-compatible storage services.

Once configured, S3 buckets appear alongside other cloud storage providers, with files available on demand. Files are downloaded as needed and automatically synchronized back to S3 when modified.

The app supports a wide range of S3-compatible services, including AWS S3, BackBlaze B2, CloudFlare R2, DigitalOcean Spaces, MinIO, and others.

Files and directories can be uploaded through the system share sheet on iOS and the Services menu on macOS. The app remembers preferred upload destinations for different file types, streamlining file management.

Pre-signed sharing links can be generated directly from Finder and the Files app, allowing temporary access to files for up to seven days.

Support for server-side encryption with customer-provided keys (SSE-C) and client-side AES-GCM encryption compatible with the Amazon S3 Encryption Client.

Comprehensive support for Shortcuts automation enables operations such as listing, downloading, uploading, and moving files.

The app is free to use with a single server. A Pro Unlock is required for multiple servers, available as a one-time purchase or a monthly subscription, with access shared across iPhone, iPad, and Mac. A one-week free trial allows users to evaluate Pro features before purchase.

### 5/5 — Must Have List: Top 10

*2026-08-21*

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.

### 5/5 — Very satisfied

*2026-08-20*

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.

### 5/5 — PERFECT!!

*2026-08-11*

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

### 5/5 — Works perfect!

*2026-07-24*

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

### 5/5 — MMM

*2026-07-13, version 2025.33*

Fret

### 5/5 — Simply Fantastic

*2026-06-23*

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.

### 5/5 — Great functionality

*2026-06-14*

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.

### 1/5 — Not useful

*2026-06-13, version 2026.28*

Not intuitive, difficult to setup and to use.

### 5/5 — Perfection

*2026-06-09*

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.

### 2/5 — 就写了两字要钱

*2026-06-02*

一般般，不好用，还不如网页端

**Developer response:** 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。

Dateien, die von Amazons eigenen S3-Verschlüsselungsclients in bestimmten Konfigurationen verschlüsselt wurden, lassen sich jetzt in der App öffnen.

Clientseitig verschlüsselte Uploads können nun auch von diesen Clients gelesen werden, und du wählst für jeden Server unter „Verschlüsselungsformat“ das gewünschte Format.

Improvements to Finder/Files app location.
