What is Which Trainer and how does it work

Which Trainer is an Android application that allows you to modify game data in real time. It works on the principle cheat-engine for a PC: it scans the device’s memory, finds values ​​(for example, the number of ammo, character health or game currency) and replaces them with those specified by the user. Unlike classic cheats, Which Trainer does not require root access, but its capabilities are limited by the protection of the game itself.

Main functions of the utility:

  • 🎯 Changing game parameters: health, damage, movement speed, amount of resources.
  • 💰 Currency generation: gold, diamonds, crystals and other in-game money.
  • 🔓 Unlocking content: skins, weapons, levels that are usually opened for real money.
  • 🛡️ Bypassing some anti-cheat system (but not all!)

The simulator supports most popular mobile games, but its effectiveness depends on the version of the game and its level of protection. For example, in Genshin Impact or Honor of Kings Which Trainer can only work on private servers, while in offline projects like Dead Cells or Shadow Fight 2 the chances are higher.

⚠️ Attention: Using Which Trainer in online games with server verification (for example, Clash of Clans or Brawl Stars) is almost guaranteed to lead to an account ban. Developers monitor not only changes in memory, but also suspicious activity (for example, a sharp increase in resources).

Where is it safe to download Which Trainer for Android

Official website or Which Trainer page Google Play does not exist - the application is distributed through third-party sources. This automatically increases the risk of downloading viruses, spyware or counterfeits. We analyzed the most reliable sites where the likelihood of running into a malicious file is minimal:

Source Link (for search) Pros Cons Risk viruses
APKMirror apkmirror.com Checking files for viruses, version history There may not be the latest version Low
APKPure apkpure.com Fast version updates, user reviews Advertising, clones are possible Medium
Telegram channels Search for "Which Trainer" Current versions, community support High risk of fraud High
4PDA Forum 4pda.to Moderated files, discussions Difficult to find a current topic Low

Required before downloading check:

  • 🔍 File name: must contain the version (for example, Which_Trainer_v3.12.apk). Avoid files with postfixes like "_premium" or "_hack" - these are most often fakes.
  • 📥 File size: The original Which Trainer weighs about 10–15 MB. Files smaller 5 MB or larger 50 MB should raise suspicion.
  • 🛡️ Hash Sum: if the forum contains MD5 or SHA-1 the original file, check it using applications like Hash Droid.
⚠️ Attention: Never download Which Trainer from sites that require disabling Google Play Protect or install additional APK files (“for correct operation”). This is a classic Trojan distribution scheme.

Step-by-step guide for installing Which Trainer

Installing Which Trainer on Android requires preparing the device. Here is the detailed algorithm:

  1. Allow installation from unknown sources:

    Go to Settings → Security → Unknown sources (on new versions of Android: Settings → Applications → Special access → Installing unknown applications) and select the browser or file manager through which you will install the APK.

  2. Download and check the file:

    Follow the recommendations from the previous section. After downloading, open the file via Total Commander or FX File Explorer and click "Install".

  3. Run the application and provide rights:

    Which Trainer will request access to Overlay other applications (for working with games) and Device memory. Without these permissions, the trainer will not be able to modify games.

  4. Set up exceptions for the antivirus:

    Add Which Trainer to the exceptions of your antivirus (for example, Avast or Kaspersky), otherwise it may block changes in the game memory.

If, after installing Which Trainer does not start or gives an error "Detected root" (even if there is no root access), try:

  • 🔄 Reboot the device.
  • 🗑️ Clear the application cache in Settings → Applications → Which Trainer → Memory.
  • 📱 Install an older version trainer (sometimes new versions conflict with firmware).
💡

If the game crashes when launched with Which Trainer, try disabling the "Auto-update values" option in the trainer settings. Some games detect active memory scanning and block access.

How to use Which Trainer: basic settings

The Which Trainer interface is intuitive, but may seem complicated for beginners. Let's look at the main steps:

  1. Selecting a game:

    Launch Which Trainer, then open the target game. In the list of processes (Process List) find its name (for example, com.tencent.ig for PUBG Mobile) and click on it.

  2. Search for value:

    Enter the current value of the parameter you want to change (for example 100 for health). Click Search and wait for the scan to complete.

  3. Filtering results:

    Change the value in the game (for example, take damage) and repeat the search. This will help narrow down the list of memory addresses.

  4. Changing a parameter:

    Highlight the found addresses, enter a new value (for example, 9999) and press Change. Some games require Freeze (freezing the value) so that it does not reset.

For convenience, Which Trainer has the following functions:

  • 🔄 Auto-update: automatically applies changes at a specified frequency.
  • 📋 Address lists: saving frequently used modifications.
  • 🔍 Advanced search: filtering by data type (4-byte, float etc.).

Which Trainer does not work with games that use server data synchronization (for example, Clash Royale or Raid: Shadow Legends). In such cases, the changes will be applied locally, but after restarting the game or synchronizing with the server, everything will be reset.

What to do if Which Trainer does not find the value?

1. Make sure the game is running and the parameter is visible on the screen (for example, a health bar).

2. Try a different search type (for example, instead of "Exact" select "Fuzzy").

3. Some games encrypt data - in this case Which Trainer is useless.

4. Update the version of the simulator or try an alternative (for example, GameGuardian).

Risks and how to avoid them

Using Which Trainer is associated with several threats that can be minimized:

Risk Consequences How to avoid
Account ban Loss of progress, purchases, access to the game Use only in offline games or in the sandbox
Viruses/spyware Software Data theft, advertising, system damage Download only from trusted sources, scan APK
Conflict with anti-cheat Game crash, device ban (by IMEI) Do not use in games with BattlEye or Easy Anti-Cheat
Incompatibility with Android The trainer does not work or causes lags Update Which Trainer and device firmware

Owners of Huawei i Xiaomi:

  • 📱 Huaweidevices need to be especially careful: Built-in Huawei Mobile Services can block Which Trainer as “suspicious software”. The solution is to disable App Check in the security settings.
  • 📱 Xiaomi: Function MIUI Optimization interferes with the operation of the simulators. Disable it in Settings → Accessibility → MIUI Optimization.
⚠️ Attention: If after using Which Trainer the game stops starting, clear its cache and data in Settings → Applications. If this doesn't help, reinstall the game. As a last resort, you may need to reset the device to factory settings (but this will delete all data!).

Which Trainer Alternatives: What to Choose

If Which Trainer is not suitable (for example, does not find values or conflicts with the game), consider alternatives:

Application Pros Cons Requires Root?
GameGuardian More functions, support for Lua scripts More difficult to configure, frequent bans No (but more effective with root)
Cheat Engine (Android) Similar to the PC version, powerful memory scanner Unstable on new Android, complex interface Yes
SB Game Hacker Simple interface, works without rue Limited capabilities, outdated versions No
Lucky Patcher Can bypass licenses, modify APK High risk of ban, does not work with online games No (partially)

For games with high protection (for example, Genshin Impact or Diablo Immortal) simulators are practically useless. In such cases, the only legal way to get an advantage is:

  • 🎮 Participation in official events (they give bonuses).
  • 💳 Purchasing in-game packs (if you are ready to invest).
  • 🤝 Joining guilds/clans for joint farming.
💡

The best alternative to cheats is mastering the mechanics of the game. Many “impossible” levels are solved with the right strategy, and not by modifying parameters.

Frequent errors and their solutions

Which Trainer users often encounter common problems. Here's how to solve them:

Error Cause Solution
"Game not found" The game is not running or is hidden from scanning Run the game, give Which Trainer overlay rights
"Root required" The game uses protected memory Get root access or try another utility
The game crashes when the value changes Anticheat detected interference Disable auto-update, use manual mode
"Failed to change value" The memory address is protected or has changed Repeat the search after restarting the game

  1. Roll back the version of the trainer (download an older one from APKMirror).
  2. Disable battery optimization for Which Trainer in Settings → Applications → Battery.
  3. Install Magisk (for devices with root access) and hide root status from games.

The likelihood of a ban in offline games is minimal, but there are nuances:

  • 📴 If the game has a cloud save (for example, via Google Play Games), changes may be synchronized and cause suspicion.
