Can You Really Run Delta on iPhone Without Jailbreak?
Yes. Delta Executor ships as a sideloadable IPA that installs on stock iOS via Apple-configured signing certificates. You don't need to jailbreak your iPhone or iPad. The sideload process uses tools that Apple permits for legitimate developer use (TestFlight, AltStore, Sideloadly, Scarlet, eSign), and the resulting install behaves like a normal app — minus the App Store distribution channel.
This works because Delta's IPA is signed with a developer certificate that gets refreshed every 7 days on free Apple IDs and every 12 months on paid Apple Developer accounts. When the certificate expires, you re-sign the IPA. The process takes about 30 seconds on a PC or Mac, or about 2 minutes on a Chromebook or even directly from your iPhone using a cloud signing service.
Before you start: you need an iPhone or iPad running iOS 15.0 or newer (Delta dropped iOS 14 support in late 2025), at least 200 MB of free storage, and either a Mac/PC for the AltStore or Sideloadly method, or just your phone for cloud signing services.
Method 1 — Sideload via AltStore (Recommended)
AltStore is the most popular sideloading tool for iOS because it's free, open source, and uses your own Apple ID to sign apps. Apple permits self-signing for up to 3 apps per device on free Apple IDs, which is enough for Delta plus your other daily-driver sideloads.
Step 1: Install AltStore on your PC or Mac
Download AltStore from altstore.io. The site provides separate installers for Windows and macOS. Windows users also need to install iTunes and iCloud from Apple's site (not the Microsoft Store version) so AltStore can communicate with your iPhone.
Run the AltStore installer and follow the setup wizard. AltStore installs itself as both a desktop app and a system service that runs in the background.
Step 2: Connect your iPhone or iPad
Plug your iPhone into your computer via USB. Trust the computer when prompted on your phone (Settings → General → Device Management → Trust). AltStore should detect your device automatically.
Step 3: Install AltStore on your iPhone
In the AltStore desktop app, click the AltStore icon in the menu bar (macOS) or system tray (Windows) and select "Install AltStore" → your device name. Enter your Apple ID email and password when prompted. Use a dedicated Apple ID if you can — sideloading many apps on your primary Apple ID can occasionally trigger Apple's security review.
Within about 30 seconds, AltStore appears on your home screen as an app.
Step 4: Download the Delta IPA
On your computer, go to deltaexecutor.world/download and download the Delta IPA. Transfer it to your iPhone via AirDrop, iCloud Drive, or by opening the download link directly on your phone inside Safari.
Step 5: Sideload Delta via AltStore
Open AltStore on your iPhone. Tap the "+" icon at the bottom of the Apps tab. Browse to the Delta IPA you just transferred and tap it. AltStore signs the IPA with your Apple ID and installs it. Within about 20-30 seconds, Delta appears on your home screen.
Step 6: Trust the developer certificate
iOS won't let you launch Delta until you trust the certificate Apple generated for your Apple ID. Go to Settings → General → VPN & Device Management → tap your Apple ID under "Developer App" → tap "Trust" → confirm. Now you can launch Delta.
Step 7: Set up AltStore background refresh
Free Apple ID certificates expire after 7 days. To keep Delta working, AltStore needs to re-sign the IPA in the background. Enable "Background Refresh" in AltStore's settings, and make sure AltStore itself stays installed on your phone. As long as you open AltStore once every 7 days, Delta will continue to work without any action on your part.
Method 2 — Sideload via Sideloadly
Sideloadly is a popular alternative to AltStore. It's a Windows/Mac/Linux app that signs IPAs using your Apple ID and installs them directly via USB. Sideloadly is faster than AltStore for one-off installs but doesn't handle auto-refresh, so you'll need to re-sign every 7 days manually.
Download Sideloadly from sideloadly.io. Connect your iPhone via USB. Drag the Delta IPA into Sideloadly, enter your Apple ID, and click "Start." Sideloadly signs and installs Delta. Trust the certificate the same way as the AltStore method. Re-run Sideloadly every 7 days to refresh.
Method 3 — Scarlet, eSign & TrollStore
These three alternatives are popular in the Roblox exploit community because they don't require a computer for the install — everything happens on the iPhone itself.
Scarlet is an online signing service that lets you paste an IPA URL and have it signed and installed directly on your phone. Open scarlet-ios.com in Safari, paste the Delta IPA download link, and follow the prompts. Certificates last 7 days on free accounts.
eSign works similarly. Install the eSign app from any reputable signing service (check the official Delta Discord for current recommended resellers), then import the Delta IPA, sign, and install.
TrollStore is the holy grail of iOS sideloading because it installs IPAs with permanent certificates — no 7-day refresh. The catch is TrollStore only works on iOS 14-16.1.1 on specific device/CPU combinations. If you're on iOS 15.0-16.1.1 on an A12 chip or older (iPhone X and earlier), TrollStore works and Delta installs permanently. Check the TrollStore compatibility list on ios.trollstore.org to see if your device qualifies.
Getting Your Key on iOS
Delta's key flow on iOS is identical to the other platforms. Tap "Get Key," complete the in-browser verification, and paste the key back. The HWID is tied to your device, not your Apple ID, so resetting your phone requires a fresh key.
Attaching Delta to Roblox on iOS
Open Roblox and join a game. Switch to Delta and tap "Attach." Because iOS sandboxes apps more strictly than Android, the attachment process takes about 3-5 seconds versus 2-3 on Android. The first attach after install sometimes takes 10-15 seconds while Delta initializes the iOS-specific injection hooks.
Common iOS Issues & Fixes
"Untrusted Developer" prompt every time
This means you didn't trust the developer certificate. Settings → General → VPN & Device Management → tap your Apple ID → Trust.
Delta won't open after the 7-day certificate expires
Re-sign the IPA via AltStore or Sideloadly. Open AltStore once every 7 days and tap Delta in the Apps list to refresh it. If you miss the window, just re-run the install — your data is preserved.
"Unable to verify app" on iOS 17
Apple tightened sideload verification in iOS 17. If you see this message, you need to enable Developer Mode: Settings → Privacy & Security → Developer Mode → Toggle on → Restart.
Should You Use a Paid Apple Developer Account?
Paid Apple Developer accounts ($99/year) let you sign apps with certificates that last 12 months instead of 7 days. If you only use Delta occasionally, the free 7-day cycle is fine. If you want zero maintenance, a paid account is worth it. Note that Delta itself is free either way — the $99 goes to Apple, not to Delta.
Final Notes on iOS Safety
Delta Executor for iOS is safe in the same sense that Delta for Android and PC is safe — the official IPA is clean, but you assume the same account ban risk as any executor. Use a secondary Roblox account, never your main. Read our full safety review for the honest breakdown.
