Introduction

Apple’s ecosystem typically restricts installation to App Store apps, but many users and developers seek to sideload third-party IPAs for testing, emulation, or apps not approved by Apple. Sideloading requires workarounds, developer certificates, or exploiting OS vulnerabilities. This guide covers five major methods:

1. Sideloadly (PC required)
2. SideStore (PC required for initial setup, then no PC)
3. AltStore (PC required)
4. KSign iOS (no PC required)
5. TrollStore (on-device permanent sideload via CoreTrust bug)

Each section provides prerequisites, step-by-step instructions, pros/cons, and troubleshooting tips. We also include general safety advice. Citations reference official sites and authoritative guides.

General Prerequisites & Caveats

• Apple Developer Account:
  • Free: up to 3 sideloaded apps, certificates expire after 7 days.
  • Paid: up to 100 devices, certificates expire after 1 year; removes many limits.
• Developer Mode (iOS 16+): must be enabled on device before installing non-App Store apps: Settings > Privacy & Security > Developer Mode.
• Trust Profiles: After sideload/install, go to Settings > General > VPN & Device Management (or Device Management/Profiles & Device Management), then Trust the appropriate developer or enterprise profile.
• Certificate Revocation: Shared credentials (enterprise certificates, public signing services) may be revoked by Apple, breaking sideloaded apps. Paid Developer accounts reduce but do not eliminate risk if using Apple’s signing.
• Source Safety: Only install IPAs from trusted sources; third-party apps bypass App Store review. Scan for malware or privacy concerns.
• Backups: Backup device data before extensive sideloading/testing.
• OS Version Compatibility: Some methods depend on iOS version; always verify compatibility (e.g., TrollStore works only on certain iOS releases exploiting CoreTrust bug).
• Network & PC Setup: For PC-based methods, require Windows (7+) or macOS (10.12+), iTunes (Windows web version), and stable USB/Wi-Fi connectivity.

Always refer to official documentation for the latest instructions, as Apple may change security measures in new iOS versions. (sideloadly.io, altstore.io)

4. KSign iOS (No PC Required)

Overview

KSign iOS is an on-device IPA signing tool using enterprise certificates and DNS profiles. No computer or jailbreak required. Users install KSign app via profile, import certificates, and sign/install IPAs entirely on-device.
(ksign-ios.com)

Prerequisites

• Device: iPhone/iPad running iOS 14+ up to iOS 18.x (depending on KSign support).
• Internet: for DNS profile and certificate downloads.
• Apple ID: not strictly needed; uses enterprise certificates provided by KSign or custom certificates if you have your own (but generating your own requires PC).
• Trust: must trust enterprise profiles on device.

Step-by-Step Guide

1. Enable Developer Mode: Recommended on iOS 16+, though enterprise installs may work without it.
2. Install KSign DNS/Profile:
   • Open Safari, go to https://ksign-ios.com/ (ksign-ios.com)
   • Tap “KSign DNS Profile” to download config profile.
   • Go to Settings > General > VPN & Device Management, install and trust the DNS profile.
3. Install KSign App:
   • After profile, KSign icon appears. Launch it; when “Untrusted Enterprise Developer” appears, go to Settings > General > VPN & Device Management, trust the enterprise certificate.
4. Import Certificate:
   • In KSign app, tap “Download KSign Certificate.” Download file; open in Files app and extract.
   • In KSign app Settings, “Add Certificate” > “Import KSign File.” Select and import certificate.
5. Install IPA:
   • In KSign app, go to “Files” or “Library,” tap “+” > “Import From Files” > select IPA.
   • After import, select IPA and tap “Sign and Install”; confirm to begin installation.
   • Trust the installed app’s profile in Settings if prompted.

5. TrollStore (On-Device Permanent Sideload)

Overview

TrollStore is a “jailed permasigned app installer” that exploits a CoreTrust bug to permanently install IPAs on certain iOS versions, without requiring a PC or jailbreak. Once set up, installed apps do not expire or require re-signing every 7 days.
(trollstore.app, github.com)

Compatibility & Requirements

• Supported iOS Versions:
  • TrollStore 2 supports iOS 15.5–16.5 (all devices), iOS 16.5.1–16.6.1 (A8–A11 devices), and iOS 17.0 (A12+ devices) where CoreTrust bug exists. Earlier TrollStore versions support iOS 14.0–15.4.1. Unsupported on iOS 16.7+ (no CoreTrust bug) or iOS 17.0.1+. (trollstore.app, ios.cfw.guide)
• Device: Non-jailbroken iPhone/iPad on compatible iOS build. Enable Developer Mode (iOS 16+).
• No PC Required: Entirely on-device via IPA installers and persistence helpers.
• Official Source: https://trollstore.app/ (trollstore.app)
• Technical: Exploits AMFI/CoreTrust vulnerability; requires installation vector per iOS version (e.g., TrollHelperOTA, TrollInstallerMDC, Misaka, etc.).
• Persistence Helper: Ensures TrollStore and installed apps remain “System” apps to survive icon cache reloads; otherwise apps may disappear or fail to launch.
• Risks: When Apple patches the CoreTrust bug, TrollStore cannot be installed on newer iOS; existing installs may fail after OS update.
• Community: Follow official TrollStore blog and GitHub (https://github.com/opa334/TrollStore) for guides and updates. (trollstore.app, github.com)

Step-by-Step Guide

Note: Installation steps vary by device chipset (A8–A11 vs A12+) and iOS version. Always refer to the latest guides on TrollStore site or linked community instructions for your exact OS/build.

1. Verify iOS Version & Device: Check Settings > General > About > Software Version. Confirm it falls within supported ranges.
2. Enable Developer Mode (iOS 16+): Settings > Privacy & Security > Developer Mode.
3. Download TrollStore Installer Files:
   • Visit https://trollstore.app/ and check “Download TrollStore” section. Choose correct installer (e.g., TrollHelper, TrollInstallerMDC, Misaka) for your iOS version and device. (trollstore.app)
4. Install TrollStore:
   • Follow the specific installer instructions (e.g., open IPA in another sideloading tool like AltStore/Sideloadly or use Scarlet/AppDB if already jailbroken/trusted). Some methods may require initial sideload via AltStore or an exploit-based in-app installer.
   • After installation, trust the TrollStore app profile under Settings > General > Device Management.
5. Install Persistence Helper:
   • In TrollStore UI, install the persistence helper which replaces a stock system app, keeping TrollStore and its installed apps at “System” level so they survive system icon cache reloads. Trust any new profiles if prompted.
6. Use TrollStore to Install IPAs:
   • Launch TrollStore on device. Use “Open In…” from Files or Safari to open an IPA in TrollStore; it will permasign and install the IPA.
   • Installed apps do not expire; no periodic re-signing needed.
7. Update TrollStore:
   • When new TrollStore versions release, download updated TrollStore.tar or IPA from GitHub. Open it in TrollStore to update itself and persistence helper; may require respring.
8. Troubleshooting:
   • If apps disappear or fail, reinstall persistence helper.
   • If TrollStore or persistence helper breaks after OS update or icon cache reload, follow community guide to reapply.
   • For unsupported iOS (e.g., iOS 17.0.1+), no installation vector exists until new exploit emerges; cannot use TrollStore.
   • Follow official blog announcements for version-specific instructions. (trollstore.app)

Pros & Cons

• Pros:
  • Permanent sideload: no 7-day/1-year expiry; unlimited installs; no PC required after initial exploit; no periodic refresh.
• Cons:
  • Works only on specific iOS versions with CoreTrust bug; when Apple patches bug, cannot install on newer OS; complexity varies per version; reliance on exploits (may be blocked by Apple updates); potential stability issues if persistence helper not maintained; security considerations running permasigned apps.

FAQ

Q1: Do I need a computer to sideload apps on iOS?

• A: Methods like Sideloadly, AltStore, and SideStore require a PC for initial sideloading or refresh. KSign iOS and TrollStore operate on-device (no PC), but have limitations (certificate revocation for KSign; OS compatibility for TrollStore). (ksign-ios.com, trollstore.app)

Q2: What happens when a sideloaded app’s certificate expires or is revoked?

• A: For free Apple Developer accounts (7-day expiry), use Sideloadly/AltStore/SideStore to refresh before expiry. For KSign iOS, re-import updated certificates manually. For TrollStore, installed apps do not expire on supported OS, but when Apple patches the exploit, TrollStore cannot install on newer OS. (ios.cfw.guide, trollstore.app)

Q3: Which iOS versions support TrollStore?

• A: TrollStore 2 supports iOS 15.5–16.5 (all devices), 16.5.1–16.6.1 (A8–A11), and iOS 17.0 (A12+). Not supported on iOS 16.7+ or iOS 17.0.1+ unless a new exploit emerges. (trollstore.app)

Q4: Is sideloading legal?

• A: Sideloading tools themselves are legal in many jurisdictions, but installing pirated apps is illegal. Installing self-developed or legally distributed IPAs for testing or personal use generally falls within acceptable use but check local laws and Apple’s terms. Always respect intellectual property rights.

Conclusion

Sideloading extends iOS/iPadOS capabilities beyond App Store constraints but involves complexities: certificate management, tool maintenance, OS compatibility, and security considerations. This guide covered five methods:

1. Sideloadly: Desktop-based with advanced options, automatic refresh.
2. SideStore: One-time PC pairing, then on-device VPN-based refresh.
3. AltStore: App-store-like experience; periodic PC refresh required.
4. KSign iOS: Pure on-device IPA signing; manual renewals.
5. TrollStore: Permanent permasigning on supported iOS via CoreTrust exploit.

Choose the method that fits your workflow, device OS version, and risk tolerance. For stability, a paid Apple Developer account with Sideloadly/AltStore is reliable. For permanent installs on compatible OS, TrollStore is unmatched until Apple patches the vulnerability. For pure no-PC convenience, KSign is easiest but expect frequent certificate updates and revocations. SideStore sits in between, offering no-PC routine use after initial setup.

Stay updated by following official blogs, GitHub repos, and community forums, and always practice safe sideloading by verifying IPA sources and backing up your device. Publish date: June 2025; revisit this guide when new iOS releases or tool updates emerge.
