Essential Key Tools

About this app

Make the Nothing Phone Essential Key work your way — no root or computer required.

Choose a different shortcut for a single, double, triple, or long press. Open an app, toggle the flashlight, take a screenshot, lock the screen, control media, or change the ringer mode.

What you can do

* Give each press pattern its own shortcut.
* Teach the app which button is your Essential Key with a quick guided setup.
* Change your shortcuts whenever you want.
* Use the optional single-press wizard to open Nothing's App Info pages, where you can manually disable or restore Essential Space and Recorder.
* Enjoy a clean interface inspired by Nothing OS.

Essential Key Tools requires a Nothing Phone with an Essential Key and Android 15 or later.

Why the app asks for accessibility access

Essential Key Tools uses Android's AccessibilityService API only to detect Essential Key presses while the app is not open and run the shortcut you selected. When enabled, it receives which hardware button was pressed or released and when. This lets it tell a single, double, triple, or long press apart.

Key presses are processed immediately on your device. Hardware key-event details are not saved, uploaded, or shared. Your shortcuts and the Essential Key identifier you confirm during setup are stored only on your device. The app does not read screen content, text fields, or anything you type. Screenshot and Lock screen run only when you choose one of them as a shortcut.

You decide whether to use accessibility access during setup. Choosing not to use it does not enable the service.
