FLEX (FLEXing) #

Open Source ★ 14.6k Updated 2026-04

A debugger that runs right inside your iOS app. You can poke around the UI and change variables (like flipping 'isPremium' to true) without even needing a computer.

Pro Tip: This is what people use for those 'Flex patches'—you just find a method like 'isPremium' and flip it to true.

The modern iOS memory editor people reach for when old iGameGuardian setups are not enough. It gives you exact and fuzzy scans, value locking, speed changes, and an overlay that works across jailed and jailbroken workflows.

Pro Tip: Use it when you need Cheat Engine-style poking on iPhone. The jailed flow still means injecting or sideloading the target app, so test on throwaway apps before you burn time on a real setup.

H5GG #

Open Source ★ 795 Updated 2024-06

An iOS mod engine built around JavaScript APIs and HTML5 UI. It is useful when you want memory scripts, patch buttons, and a floating menu without building the whole interface in Objective-C.

Pro Tip: Good for quick menus and scriptable patches. The web UI angle is the real win: you can sketch the interface in HTML and CSS, then wire it into memory work with JavaScript.

Theos #

Open Source ★ 4.9k Updated 2026-04

The engine behind almost every iOS game cheat. It uses a simple syntax called 'Logos' that makes it easy to hook into game functions. If you see an iOS mod menu, it was almost certainly built with this.

Pro Tip: You'll need a Mac or a Linux environment to build tweaks with Theos. It is the standard for anyone serious about the iOS scene.
