Introduction
VansonMod is an independent iOS debugging tool built for the TrollStore environment. It works externally and supports common workflows on TrollStore devices, including process selection, memory search, memory browsing, pointer analysis and verification, signature analysis, scripting, Hex editing, and app archive management.
On jailbroken devices, VansonMod also provides deeper code-level workflows such as RVA patching and hardware watchpoint monitoring. The current public source line has grown into a broader iOS debugging workstation for iPhone and iPad, with split view, landscape, and Stage Manager support.
Compatibility
Platform: iOS 14.0+
Install method: TrollStore for the main .tipa package
TrollStore workflows: process selection, memory search, nearby search, result filtering, memory browsing, Hex editor, pointer analysis and verification, signature analysis, script tools, app archive management, themes, language settings, and icons
Jailbreak-oriented workflows: RVA Patch, RVA record management, and hardware watchpoint monitoring, especially in Dopamine / palera1n style environments
Runtime access: some features depend on successful access to the target process task port, so behavior can vary by environment and target app state
AMFI note: on stock TrollStore devices, directly modifying executable __TEXT pages usually causes the target app to crash. Use RVA patching and code-level workflows in a suitable jailbreak environment.
Highlights
Process and app management: Running / All / System views, localized app names, version display, starring, PID / Bundle ID copying, quick launch, and process termination.
Memory search and batch editing: exact, fuzzy, group, range, and nearby search modes, plus greater-than / less-than / between filters, fixed value writes, incremental edits, batch lock, batch favorite, and batch delete.
Memory browser and Hex editor: address jumping, auto refresh, string view, batch address copying, Hex / Split / Text layouts, row editing, offset jumps, and fast writes.
Pointer analysis and verification: manual and automatic pointer chains, static / dynamic / all / backtrack modes, real-time verification, incremental snapshots, changed-region comparison, verifier file save/import/export, and lock integration.
Signature analysis: address-to-signature workflow, module scope selection, global search, smart masking, verification, and toolbox saving.
Script system: built-in JavaScript runtime with examples, shortcuts, console output, and in-app guides.
RVA debugging and watchpoint monitor: module selection, offset patching, ARM64 instruction presets, RVA record management, hardware watchpoint monitoring, hit records, code inspector, and quick sending of hit locations into the RVA debugger.
App archives and process audit: one-tap backup/restore for Documents and Library, Files app import/export, code-location diff export, and original-byte restore.
Settings and UX: theme switching, language switching, app icon switching, tab reordering, fuzzy search range control, lock interval, prevent sleep, result limits, update checks, iPad split view, landscape, and Stage Manager support.

VansonMod is provided for security research, reverse engineering learning, and compliant technical testing.
This is a general-purpose debugging utility. It ships without preset targets, app-specific bypasses, private adaptations, or bundled target data.
Users are responsible for their own actions and environment. Target app crashes, data loss, account restrictions, device instability, and legal responsibilities belong to the user.
