中文版

iPAGet（GitHub：https://github.com/ipaget/ipaget ，出自 LINUX DO 社区，CC BY-NC-SA 4.0）是一个跨平台的桌面应用：App Store 下载器加 IPA 管理器，Windows、macOS、Linux 都能用。用 Apple 账号登录后，它直接从苹果服务器下载 IPA，最大的卖点是能下载任意历史版本——App Store 里早已下架的旧版，只要苹果服务器还留着、你的账号有授权，就能拉回来。

它能干什么

• 下载与版本：按地区搜索 App Store、看榜单、详情和更新日志；下载最新版，或从版本历史里选任意旧版本；还能读取设备上已装 App 的构建标识，下载同一个版本回来（是从苹果重新下载，不是从设备里提取）
• 多账号与本地库：支持多个 Apple 账号，显示下载进度与速度，下载或导入的 IPA 统一收进本地库管理，方便日后重装
• 设备管理：USB 连接 iPhone/iPad，查看设备信息、已装 App 与占用空间，安装/卸载 App，在 iOS 开放的应用容器范围内传文件
• IPA 检查与编辑：查看 bundle id、版本号、最低系统要求、描述文件、entitlements、框架和加密状态；能改 App 显示名、图标和 Info.plist 后再导出，plist 支持树形与 XML 两种编辑
• 证书与签名：导入已有证书，或用开发者账号申请签名证书，给 IPA 签名或重签名

怎么用

• 在 Releases 下载对应系统的包：Windows 用 msi 或 setup 安装包，macOS 是通用版 dmg（Apple Silicon 与 Intel 都行），Linux 是 AppImage
• 注意：macOS 版未签名未公证，首次启动要右键 → 打开（或去掉隔离属性）；Windows 版未签名，可能触发 SmartScreen，确认来源后选「仍要运行」
• 流程：登录 Apple 账号（需过双重验证）→ 搜索 App → 选最新版或历史版本下载。下载 IPA 不需要连接设备，检查本地 IPA 也不需要账号

关于 DRM，先说清楚

• 下回来的是 App Store 原包：主程序仍带 FairPlay 加密，绑定你的账号授权。iPAGet 自带的重签名不会去除 DRM，这一点作者在 README 里写明了
• 想脱壳：把包装到越狱设备上运行后用工具从内存 dump；或者用本站此前介绍的 fairplay-decrypt，先给同账号取一次凭证，之后该账号的 IPA 都能在电脑上离线解密
• PlayCover 只接受解密后的 IPA，所以完整链路是：iPAGet 下载（含旧版本）→ 解密 → 导入 PlayCover

适合谁

需要旧版本 IPA 的人：想给 App 降级、给老设备留兼容版本、做版本对比或逆向研究。项目还很年轻（2025 年 10 月创建，star 不多），底层基于 ipatool 的商店协议与 go-ios 的设备通信，技术栈是 Tauri + React + Go；另外注意，旧版本能不能下取决于苹果服务器是否还提供、以及你的账号是否有权下载，作者也不保证每个旧版都在。

English Version

iPAGet (GitHub: https://github.com/ipaget/ipaget , from the LINUX DO community, CC BY-NC-SA 4.0) is a cross-platform desktop app: an App Store downloader plus IPA manager for Windows, macOS and Linux. Sign in with an Apple Account and it downloads IPAs straight from Apple’s servers — and its headline feature is that it can download any historical version: as long as Apple still serves the build and your account is authorized for it, you can pull back versions the App Store no longer offers.

What it does

• Downloads and versions: search the App Store by region, browse charts, details and release notes; download the latest release or pick any older build from the version history; it can also read the build identifier of an app installed on your device and download that same build (a fresh copy from Apple — it does not extract the installed package)
• Accounts and local library: multiple Apple Accounts, download progress and speed, and a local library for downloaded or imported IPAs, kept for later reinstallation
• Device management: connect an iPhone or iPad over USB to view device info, installed apps and their storage use, install or uninstall apps, and transfer files through the app containers iOS exposes
• IPA inspection and editing: inspect bundle ID, version and build, minimum OS, provisioning profiles, entitlements, frameworks and encryption status; change the display name, icon and Info.plist, then export the modified IPA; plist editing in tree or XML form
• Certificates and signing: import an existing certificate or request one through a developer account, then sign or re-sign an IPA

How to use it

• Grab your platform’s package from Releases: an msi or setup installer on Windows, a universal dmg on macOS (Apple Silicon and Intel), an AppImage on Linux
• Note: the macOS build is unsigned and not notarized — right-click → Open on first launch (or strip the quarantine attribute); the Windows build is unsigned and may trigger SmartScreen — verify the source, then choose Run anyway
• Flow: sign in with an Apple Account (two-factor required) → search → download the latest or a historical version. Downloading needs no connected device, and inspecting local IPAs needs no account

About DRM — the honest part

• What you get is the original App Store package: the main binary is still FairPlay-encrypted and tied to your account’s authorization. iPAGet’s re-signing does not remove DRM — the author states this plainly in the README
• To decrypt: install the package on a jailbroken device, run it, and dump it from memory; or use fairplay-decrypt (covered earlier on this blog) — extract the account credential once, then decrypt that account’s IPAs offline on your computer
• PlayCover only accepts decrypted IPAs, so the full chain is: download with iPAGet (old versions included) → decrypt → import into PlayCover

Who it’s for

Anyone who needs older IPAs: downgrading an app, keeping a compatible build for an old device, comparing versions, or doing reverse-engineering research. The project is young (created in October 2025, few stars so far), built on ipatool’s store protocol and go-ios for device communication, with a Tauri + React + Go stack. One caveat from the author: whether an old build can be downloaded depends on Apple still serving it and your account being entitled to it — not every old version is guaranteed to be there.
