Delta Executor runs natively on iOS without a jailbreak. The build is signed with an Apple Developer Enterprise certificate and distributed as a standard IPA that you sideload with one of four free tools — AltStore, Sideloadly, ESign, or Scarlet. Each one has the same end result: a Delta icon on your home screen, ready to launch.
Pick the Right Method for Your Device
| Method | Best For | Refresh Cadence |
|---|---|---|
| AltStore | Long-term installs | Auto-renews every 7 days |
| Sideloadly | Quick sideloads via PC | Refresh every 7 days |
| ESign | On-device install (no PC) | Refresh every 7 days |
| Scarlet | iOS 14+ legacy devices | Auto-renews if installed via PC |
For most users in 2026, AltStore is the cleanest choice. It is open-source, the install is permanent (Delta auto-renews in the background), and you can manage all your sideloaded apps from a single window.
iPadOS vs iOS — What Changes
Identical app, identical behavior. The only difference is that Delta on iPadOS runs in a windowed mode (Stage Manager) if you opt in — handy if you want Roblox and Delta visible at the same time. The IPAs are identical; AltStore handles both automatically.
Method 1 — AltStore (Recommended)
- Install AltStore on your PC. Download from altstore.io and run the installer. The installer puts AltServer on your computer and asks you to install the Mail plug-in (required for the auto-renew).
- Pair your iPhone. Connect the phone via USB, open AltServer on your PC, and click Install AltStore. Enter your Apple ID once — it is used only to sign the sideloaded apps and is stored locally on AltServer.
- Download the Delta IPA. On your phone, browse to deltaxecutor.download/download and tap the iOS download button. The file is roughly 62 MB.
- Open AltStore on your phone. Tap the + button in My Apps, then choose the downloaded Delta IPA from the file sheet.
- Trust the developer. Open the iOS Settings → General → VPN & Device Management, tap the Apple ID that signed Delta, and tap Trust. Delta now launches from your home screen.
- Get your key (mobile). Open Delta, tap Get Key, complete the short in-browser flow, and paste the 36-character key. Delta is now active.
AltStore renews Delta's signing every 7 days automatically, as long as AltServer is running on the same Wi-Fi as your phone. There is no manual re-sign step for you to remember.
Method 2 — Sideloadly (Quick Sideload via PC)
Sideloadly is faster for one-off installs but does not auto-renew. Use it when AltStore is not available.
- Install Sideloadly on your PC from sideloadly.io.
- Connect the iPhone over USB.
- Drag the Delta IPA onto the Sideloadly window, enter your Apple ID, and click Start.
- Trust the certificate (same steps as AltStore, above).
- When Delta expires (after 7 days), run Sideloadly again to re-sign.
Method 3 — ESign (On-Device, No PC)
If you do not own a PC — or you want to do the whole install on the phone — install ESign from a trusted source, then use its in-app browser to fetch the Delta IPA directly. The signing step is the same. ESign auto-renews locally, but Apple limits the certificate lifetime to 7 days, so you will get a push reminder to re-sign every week.
Method 4 — Scarlet
Scarlet is the longest-running sideload app and still works for legacy iOS versions (12+). For modern iOS 15+ devices, prefer AltStore. The flow is otherwise identical: install Scarlet, point it at the Delta IPA, trust the certificate, launch.
How to Trust the Delta Developer Certificate
Every sideloaded app on iOS requires you to explicitly trust the developer before it will open. The exact prompt varies by iOS version:
- Open the iOS Settings app.
- Go to General → VPN & Device Management (older iOS) or General → Device Management (iOS 16+).
- Tap the entry that uses the Apple ID you signed with.
- Tap Trust "<your Apple ID>", then tap Trust again in the confirmation pop-up.
Run Your First Script on iOS
Once Delta is open, the iOS flow is identical to Android:
- Open Roblox, join any game.
- Tap the floating Delta icon (left edge of the screen).
- Open the Script Hub tab, find the game you joined, and pick a Verified script.
- Tap Execute.
Troubleshooting on iOS
"Untrusted Developer" — Delta won't open. Walk through the trust steps above. If the entry never appears in VPN & Device Management, it means the install failed silently — remove the app and reinstall.
"Delta disappeared from my home screen." The 7-day Apple Developer signing period expired. Open AltStore / ESign and tap Refresh on the Delta entry. Re-signing takes about 15 seconds.
"Key system says invalid." Copy the whole 36-character string, including any trailing =. Do not add spaces. If the in-app browser times out, retap Get Key — previous keys are good for 30 minutes.
Re-signing Delta After 7 Days
Every iOS install from a non-App-Store source — Delta, AltStore, ESign, anything else — expires after 7 days because Apple limits developer signing certificates to that window. Re-signing is fast and Delta handles the heavy lifting.
On AltStore, you never have to think about re-signing. The app refreshes Delta in the background as long as AltServer is running on the same Wi-Fi as your iPhone. If AltServer is offline, your next time you bring both devices onto the same network Delta will re-sign itself within a minute.
On Sideloadly or ESign, open the tool, connect or select your device, find Delta in the list, and tap Re-sign (Sideloadly) or Refresh (ESign). The process takes 15–20 seconds. Delta's app icon disappears from your home screen the moment the certificate expires, so it is always obvious when a re-sign is due.
UDID Registration & Free Developer Accounts
If you signed Delta with a free (non-Developer) Apple ID, iOS will refuse to re-sign after three days instead of seven. The fix is to register the device's UDID with your personal Apple Developer account, which costs $99/year. AltStore handles this for you automatically and is the simplest way to avoid the 3-day cliff.
To find your UDID manually, plug the iPhone into a Mac and open Finder (or iTunes on Windows). Click on the device icon, then click the serial number until it shows UDID. Copy it, then paste it into the Apple Developer portal's Devices tab. Once registered, AltStore re-signs Delta cleanly for the full 7 days, repeatedly.
iPad-Specific Notes
On iPadOS, Delta behaves identically to iOS — same UI, same scripts, same key flow. The only meaningful difference is windowing: if you have Stage Manager enabled, Delta can sit alongside Roblox in split-screen view, which makes copy-pasting loadstrings easier. Stage Manager requires an M1 iPad or newer; older iPads run Delta in the standard full-screen mode.
For users who script on an iPad Pro with a Magic Keyboard, Delta's editor tab benefits from the larger screen real estate — the multi-line Lua syntax highlighting that fits ten lines on an iPhone screen fits twenty on a 12.9-inch iPad. The cloud sync works the same way, so a script you wrote on iPad is available the moment you log into Delta on your iPhone.
Account & Roblox Notes
Delta on iOS does not require a jailbreak, so the operating system itself stays in a fully patched state. That is the cleanest part of the iOS path — the only "modification" happening is Delta adding Lua injection on top of the unmodified Roblox client. iOS isolates each app's data, so Delta cannot read your Roblox session cookie, your photos, or your Apple ID info. The key system authenticates Delta's server against your install, not the other way around.
For Roblox account safety, the same rules apply as on any other platform: use an alt account you don't care about, avoid teleport-spamming in public lobbies, and don't pair Delta with second-party overlays or auto-clickers. iOS's tighter permissions model means Delta has less visibility than on Android — that is a feature, not a bug, and it is the same reason iOS tends to get fewer of the false-positive ban reports.
What's Next
Once Delta is signed, trusted, and running on your iPhone, save your first loadstring to the Delta cloud account. The Blox Fruits script guide is a good starter — it works on iOS exactly the way it does on every other platform. The Key System Explained post is the right second read if you want to understand what the daily 24-hour rotation is doing under the hood.
