How to Download & Install Delta Executor iOS v2.737 (October 2026 Guide) — No Jailbreak Needed

Many Roblox players want a script tool on iPhone and iPad. Delta Executor is a popular Roblox script executor that lets users run custom Lua scripts in games. Delta started on Android, and its iOS version launched on August 26, 2024 (v2.638.610). Because Apple does not allow it on the App Store, it is installed through Direct Install or by sideloading the IPA, with no jailbreak required.

If you are looking for a no-jailbreak Roblox script tool for iOS, this guide covers everything from downloading the IPA to installing it with Direct Install, Scarlet, ESign and KSign. Whether you are on iPhone or iPad, these steps cover the process. Delta’s iOS builds are released almost as often as Android: between October 2025 and October 2026 there were 26 iOS builds, so check for updates regularly.

Important Legal and Ethical Disclaimer

Before diving in, a crucial note: using Roblox script tools like Delta Executor violates Roblox’s Terms of Service and can result in account bans, including temporary suspensions or permanent bans. This guide is for educational purposes only, focusing on how executors and Lua scripting work.

We strongly recommend using alternate accounts in private servers, avoiding public lobbies to reduce reports, and never running malicious scripts that could harm other players or steal data. If you want to build games legitimately, Roblox Studio lets you write and test Luau scripts safely.

What is Delta Executor for iOS

Delta Executor for iOS is a Roblox script execution tool for iPhone and iPad. It lets you run custom Lua scripts in Roblox with an executor environment that includes functions such as hookfunction, getconnections and filtergc. Delta installs on non-jailbroken devices through Direct Install or sideloading, which makes it accessible to a wide range of users.

The iOS version ships a modified Roblox app together with Delta, so you log in to Roblox inside that app. It works with the same community scripts as other platforms, and it uses a free key that is valid for 24 hours.

Latest Version of Delta Executor iOS

The latest iOS build in the developer changelog is v2.737.1581, released on September 9, 2026. It added the oth library (oth.hook, oth.unhook and related functions), debug.getcallstack, new connection helpers such as isluaconnection and getconnectionthread, a remade Regex library, and fixes for argument errors on some functions.

Earlier 2026 iOS builds brought a 50x faster decompiler and input functions (v2.708.880, February 23), raknet.desync (v2.711.871 to v2.717.982), actor and Lua-state functions (v2.729.838, July 21), and a remade Drawing library (v2.735.1135, August 25). The Direct Install option also returned on December 25, 2025 with v2.702.633, along with an easier key system. You can see every release in our Delta Executor changelog.

Delta iOS Installation Methods Compared

System Requirements for Delta Executor on iOS

• Minimum: iOS 15 or later (iPhone or iPad), about 1GB of free storage, and a stable internet connection.
• Recommended: a recent iOS version (17 or newer), 2GB or more of free storage, and Wi-Fi.

The IPA is roughly 120MB to 220MB depending on the source and build, but you need extra room for Roblox and its data. Older devices may run scripts more slowly and may close the app more often when memory is low.

Congratulations! Delta is now installed on your iPhone. Remember that apps signed with certificates can expire or be revoked, so keep the IPA handy to reinstall.

Method 3: Direct Install Method

For the simplest approach, use the Direct Install method from the official site. It does not need a computer, but it relies on an enterprise certificate, which Apple can revoke:

1. Visit ExecutorDelta.com on Safari.
2. Tap the “Direct Install” button for the latest build.
3. Follow the on-screen steps. You may be asked to complete a few tasks and then tap “Unlocked”.
4. Tap Allow when prompted, then tap Install and wait for the download and installation.

KSign is another on-device signer that can install the Delta IPA. Follow these steps:

1. Open Safari on your iPhone or iPad.
2. Search “KSign iOS download” and visit the official site.
3. Download the KSign profile and install it.
4. Go to Settings > General > VPN & Device Management and trust the KSign certificate.
5. Open KSign, tap Import from file and select your Delta IPA from Files.
6. Tap the imported IPA, select Sign and Install, and then press Start Signing.
7. Wait for it to finish; an icon will appear on your home screen.
8. Trust the new Delta profile in Settings if prompted.
9. Launch Delta, complete the key system, and test with a simple script.

Risks and Best Practices for Using Delta Executor iOS

While Delta Executor iOS offers useful features, you should be aware of these risks:

• Account Bans: Using any executor violates Roblox’s Terms of Service. Use alternate accounts in private servers.
• Fake and Malicious IPAs: Many “Delta iOS” sites are fake. Only download from ExecutorDelta.com and never install from unknown sources.
• Certificate Expiry and Revokes: Free Apple ID certificates expire after 7 days, and Apple can revoke enterprise certificates used by Direct Install at any time. Re-sign or reinstall when that happens.
• Performance: Heavy scripts may drain the battery and heat the device. Close background apps for best performance.
• Your Login: Do not use your main Roblox account, and never enter your password on any page other than Roblox’s official login.

About Roblox and Delta on Your iOS Device

Delta’s iOS package includes its own modified Roblox app, so you do not need to install anything extra for Delta to work. The regular Roblox app from the App Store is a separate app:

1. Open the App Store on your iOS device if you also want the standard Roblox app.
2. Search for “Roblox” and select the official app.
3. Tap Download and wait for installation.
4. Use the App Store version for normal play, and the Delta version only when you want to use scripts, on an alternate account.
5. Enable two-factor authentication on your main account for security.
6. Remember that scripts only run in the Delta-modified app.
