Best Productivity Apps to Sideload on iPhone

ByScarlet iOS Team Updated on

The App Store has thousands of productivity apps, but the most powerful tools for iPhone are often unavailable through Apple’s official channel. Some are rejected for policy reasons, some are developer tools with capabilities Apple restricts, and some are unlocked versions of expensive paid apps. Using Scarlet iOS, you can access a range of productivity tools that genuinely expand what your iPhone can do for work and daily efficiency.

Why Sideload Productivity Apps?

Apple’s App Store guidelines prohibit apps that access system-level features, modify other apps, or perform operations that Apple considers outside the defined user experience. This blocks a range of genuinely useful productivity tools. Sideloading bypasses these restrictions:

  • File managers that access the full iOS file system (not just the sandboxed Files app areas; this needs TrollStore or a jailbreak)
  • Automation tools with deeper system hooks than Shortcuts allows
  • Developer utilities with network inspection and debugging capabilities
  • Note-taking apps with features Apple rejects (real-time collaboration without iCloud, custom sync protocols)
  • Unlocked versions of expensive productivity apps without the subscription cost

Best Productivity Apps to Sideload

Filza File Manager

Filza is the most powerful file manager available for iOS. Originally a jailbreak tool, it also has a TrollStore version. File system access beyond the normal iOS sandbox needs TrollStore or a jailbreak; installed with a normal certificate, such as through Scarlet iOS, Filza stays inside its own sandbox like any other app. Within the access it has, you can browse, edit, copy, move, and delete files. For developers and power users who need to inspect app data, edit configuration files, or manage complex file structures, Filza is indispensable.

Filza includes a text editor with syntax highlighting for code files, a hex editor for binary inspection, a built-in audio and video player, ZIP archive management, and FTP/SFTP client integration. It replaces half a dozen specialized apps with a single comprehensive tool.

SSH Files (Secure ShellFish)

For developers who frequently need to access remote servers from their iPhone, SSH Files provides a full-featured SSH terminal and SFTP file manager. The sideloaded version unlocks the premium tier features that the App Store version gates behind a subscription: multiple concurrent SSH sessions, custom terminal themes, full keyboard shortcut support, tmux integration, and local port forwarding. If you manage servers or VMs from your phone, this is essential.

a-Shell

a-Shell is a free terminal app in the App Store with a Unix-like environment. We know of no separate “enhanced” sideloaded version: the App Store app already includes Python 3, Lua, JavaScript, a C compiler (to WebAssembly), Git and an SSH client. You can run scripts, do data analysis, and execute code directly on your iPhone. For data professionals and developers who need mobile scripting capability, a-Shell is transformative.

Scriptable

Scriptable is free on the App Store with no subscription or premium tier, so there is nothing to unlock and no reason to sideload it. Scriptable lets you write JavaScript to create custom widgets, automate iOS actions, integrate with web APIs, and build mini-apps.

GoodNotes 5 Unlocked

GoodNotes 5 was a popular handwriting and note-taking app for iPhone and iPad; in 2023 it was replaced by Goodnotes 6, which is free to try with paid plans for the full version. The unlocked IPAs around are usually of GoodNotes 5. The sideloaded unlocked IPA provides the full GoodNotes experience: unlimited notebooks, all tools unlocked, all templates available, and handwriting recognition active. Local sync and iCloud backup work for the local portion; some iCloud sync features may require the legitimate purchased version for full functionality.

PDF Expert Full

PDF Expert by Readdle is a professional PDF editor for iPhone. The full unlocked version enables PDF annotation, editing, form filling, digital signatures, PDF merging/splitting, and OCR text recognition. The App Store version requires a $79.99/year subscription for the editing features. For users who occasionally need professional PDF editing without committing to an annual subscription, the sideloaded version is a practical option.

Working Copy Pro (Git Client)

Working Copy is the best Git client for iOS. The Pro version unlocks push, SSH key authentication, multiple repository support, and integration with other iOS apps through the Share Sheet and Files app. Developers who want to review pull requests, make small code changes, and manage repositories from their iPhone will find Working Copy Pro genuinely useful for on-the-go development work.

How to Install Productivity Apps via Scarlet iOS

  1. Open Scarlet iOS on your iPhone
  2. Search for the specific app name or browse the Productivity category
  3. Tap Install: Scarlet handles downloading and signing automatically
  4. Trust the developer certificate in Settings > General > VPN & Device Management
  5. Open the app and configure your preferences

Multiple productivity apps can be installed simultaneously. They coexist without conflicts, but they are all signed with the same shared certificate, so a revocation affects all of them at once.

Automating Your iPhone Workflow

Combining sideloaded productivity tools creates powerful automation possibilities. For example:

  • Use a-Shell to run Python scripts that process data from Files
  • Use Scriptable to create widgets that display information from custom APIs
  • Use Filza (with TrollStore) to directly edit app configuration files for finer control
  • Use Working Copy to commit script updates and sync them across devices

This level of automation goes well beyond what is possible with only App Store apps and Apple’s Shortcuts. For a technical user, sideloading productivity tools turns an iPhone into a surprisingly capable work device.

Managing Multiple Sideloaded Apps

When you have many sideloaded apps, certificate management becomes important. Scarlet iOS handles signing for you, and if a certificate is revoked you can reinstall the affected apps from Scarlet once it works again.
