Preference Manager: Addon

Review by eFreeware

If you tinker with Android at a low level, Preference Manager: Addon is likely to be the sort of tool you keep around for troubleshooting. It is a free utility from Trilokia Inc. that exposes app shared preferences so you can inspect and edit them, and it is built specifically as an addon to Gamers GLTool Pro. That framing tells you a lot about the audience: this is not a general-purpose cleaner or a settings tweaker for casual users, but a debugging aid for people who already know their way around an app's internal storage.

Root access is required. Root permission is mandatory; without it, the app will not work at all. The developer also warns that it should only be used by people who understand what they are doing, because misuse can brick your device or the application you are editing. That is an unusually direct disclaimer, and it sets the tone for the whole product: it assumes competence and does not try to protect you from yourself.

What appeals to me here is the narrowness. Rather than bundling a dozen unrelated utilities, it does one job and does it for a specific workflow. If you are the kind of user who edits preferences to test how an app behaves under different configurations, that focus is a feature, not a limitation.

Built for advanced users, not casual tinkerers

The developer positions this as a tool for advanced users debugging application shared preferences. You need to understand what shared preferences are and why changing them matters before the app is useful. The developer's warning suggests they would rather you stay away until you are ready.

Root is the gate. Without it the app does not function, so a stock, unrooted phone is not a candidate. That rules out most everyday users.

The addon relationship with Gamers GLTool Pro is worth noting. This is not a standalone product in the usual sense; it is an extension of another app. If you already use that tool, this addon fits into the same workflow. If you do not, the app's purpose is harder to justify on its own.

Inspecting and editing shared preferences

The core capability is managing app shared preferences: looking at the key-value data an app stores and changing it. For debugging, that access lets you reproduce a state or verify that a setting is being written correctly.

The developer's disclaimer is the most important practical detail. Editing preferences can break an app or the device, so treat it as a tool with real consequences.

Offline by design and updated for Android 15

One detail I appreciate is the app's design. The developer's privacy policy is reassuring. For a tool that touches app internals, that is a sensible design choice.

The app was released in September 2020 and last updated in late October 2025, with the target API moved to Android 15 for Play compliance. The developer is still maintaining it.

The target API update is not a feature you will notice day to day, but it is the kind of housekeeping that keeps a root tool viable on newer Android versions. For a utility in this category, that is often the difference between something that works and something that quietly stops functioning.

What it costs

The app is free. There are no ads and no in-app purchases. That is a clean proposition: you are not trading attention or money for access, and there is no upsell to navigate.

The cost here is not financial but technical. Root access is required, and the developer warns that misuse can brick your device or application. That is the real price of admission, and it is worth weighing before you install anything. The app itself does not add a subscription or a paywall on top of that.

The install base is modest but not tiny: over 100,000 installs and a 4.2 average from 868 ratings. For a niche root utility, that suggests a small but engaged audience rather than a mass-market product. The content rating is Everyone, though the technical requirements make the effective audience much narrower.

How it compares with other root utilities

It suits people who want to inspect and change app shared preferences directly. It is a focused addon for shared preferences, tied to Gamers GLTool Pro. A general-purpose root utility would cover more ground, but it would also be less specific about this particular job.

Compared with a desktop debugging environment, this is a phone-side tool, convenient for a quick check but narrower in scope.

The closest alternatives are other root-only utilities that expose app data. This one distinguishes itself by being an addon rather than a standalone product, and by the developer's explicit warning about the risks. If you already use Gamers GLTool Pro, the integration is the main reason to choose it over a generic option.

A focused tool for rooted debugging

If you are an advanced user who already works with shared preferences and wants a phone-side way to manage them, this is a reasonable fit.

The offline design and the recent Android 15 target API update are points in its favor. With no ads and no purchases, it stays simple, and the 4.2 average from 868 ratings suggests the people who use it find it serviceable. The narrow scope is the main thing to accept: it does one job, for one kind of user.

If you are rooted, already use Gamers GLTool Pro and understand the risks, this is worth considering. If you are not rooted, or you are not confident editing app internals, the developer's own warning is the best guide: this is not the tool to learn on.

What's new in version 1.4

Updated target API to Android 15 (API 35) for Google Play compliance. Minor stability improvements.
