Best iOS Signing Method for Your Version - Decision Guide 2026
Which iOS signing method is right for your iPhone? This guide matches your iOS version to the best sideloading method — from iOS 14 TrollStore to iOS 26 SideStore and LiveContainer.
There are 10 iOS signing methods and a dozen tools. Picking the right one for your exact iOS version and needs saves hours of wasted setup time. This guide gives you a direct answer.
Step 1: Find Your iOS Version
Go to Settings → General → About → iOS Version. Note the exact version.
iOS 26 Users (Released Fall 2025)
You are on the most current iOS. No jailbreak exists. TrollStore does NOT work.
Recommended Setup: SideStore + LiveContainer
Why: SideStore is computer-free after setup, has the best iOS 26 support, and pairs with LiveContainer to bypass the 3-app limit.
Setup time: ~45 minutes (including one-time computer setup)
Cost: Free
What you get:
- Unlimited apps (via LiveContainer)
- Auto-refresh (no app expiry)
- Huge source/repo ecosystem
- JIT support for emulators (via StikDebug)
Alternative if you want zero computer involvement:→ Use Feather or KSign with a personal developer certificate. Requires purchasing an Apple Developer membership ($99/yr) or using shared enterprise certs (higher revoke risk).
EU users on iOS 26:→ Also install AltStore PAL for legal, Apple-approved sideloading of curated apps.
iOS 18.x Users (iOS 18.0 through 18.7)
Same situation as iOS 26 — no jailbreak, no TrollStore.
Recommended Setup: SideStore + LiveContainer
Identical to iOS 26. All tools work on iOS 18, with excellent stability.
Specific iOS 18 notes:
- iOS 18.4+ introduced better StikDebug compatibility
- LiveContainer reached maturity on iOS 18 — highly recommended
- All signing tools (AltStore, SideStore, Feather, KSign, Scarlet) fully support iOS 18.x
For iOS 18 power users wanting 1-year validity:→ Sideloadly with a paid Apple Developer account — sign apps that stay valid for 12 months.
iOS 17.0 Users — You Have a Special Situation
Recommended Setup: TrollStore (via TrollRestore)
You are in the most privileged position in iOS sideloading. iOS 17.0 (not 17.0.1, not 17.1 — exactly 17.0) is the last version supported by TrollStore.
What you get with TrollStore:
- Permanent app installs — no expiry, ever
- Unlimited apps — no 3-app limit
- No Apple ID needed for installing apps
- Full special entitlement support
Should you update to iOS 26?See our dedicated guide: Should You Stay on iOS 17.0 for TrollStore?
Short answer: If sideloading is a core part of how you use your iPhone, stay on iOS 17.0. If you want Apple Intelligence and the latest features, accept the downgrade to SideStore+LiveContainer and update.
iOS 17.1 through iOS 17.7 Users
TrollStore does NOT work on these versions (CoreTrust patched). No jailbreak.
Recommended Setup: SideStore + LiveContainer
Same as iOS 26. SideStore works perfectly on iOS 17.1–17.7.
Bonus on iOS 17.4+: You gain StikDebug support for JIT on iOS 17.4 and above.
EU users on iOS 17.4+: AltStore PAL is available.
iOS 16.x Users
TrollStore works on iOS 16.0 through iOS 16.6.1 — use it if you haven't updated.
If you're on iOS 16.0–16.6.1:
→ TrollStore via TrollInstallerX. Permanent installs, unlimited apps, no certificates needed. → Don't update past iOS 16.6.1 if you want to keep TrollStore.
If you're on iOS 16.7+:
→ TrollStore is patched. Use SideStore + LiveContainer same as iOS 17/18/26.
Special case — iOS 16.0–16.1.2: The MacDirtyCow exploit is available, which enables bypassing the 3-app limit in SideStore even without LiveContainer.
iOS 15.x Users
TrollStore works on all iOS 15 versions. Full jailbreaks are available (Dopamine, Palera1n).
Recommended: TrollStore (via TrollInstallerX)
Permanent installs, unlimited apps. Well-established support.
If You Want a Jailbreak:
- Dopamine — works on A12+ devices on most iOS 15 versions
- Palera1n — for A8–A11 devices (computer required, semi-tethered)
iOS 14.x Users
Full jailbreak available (Unc0ver, Checkra1n, Dopamine). TrollStore original supported.
Recommended: Jailbreak (Unc0ver or Dopamine)
iOS 14 has the most mature jailbreak ecosystem. If you're still on iOS 14, a full jailbreak gives you the most features.
Alternative: TrollStore first generation — permanent sideloading without jailbreak.

The "I Just Want One App" Scenario
You want YouTube++ and nothing else, on iOS 26:→ Install AltStore, use 1 of your 3 app slots for YouTube++. Done. No LiveContainer needed.
You want 5+ apps on iOS 26:→ Install SideStore + LiveContainer. Put the additional apps inside LiveContainer.
You want emulators with JIT on iOS 26:→ SideStore + StikDebug. Optional: TrollStore on iOS 17.0 for the cleanest JIT experience.
