Klick'r for Android (formerly Smart AutoClicker)
Open-source image detection auto clicker - clicks when a specific element appears on screen, not on a timer
Overview
Klick'r, developed by Nain57 and available on GitHub, is the only open-source auto clicker on this list and the only one that operates on image detection rather than a fixed timer. In Regular Mode it works like any auto clicker: tap a location at a set interval. In image detection mode, it watches the screen for a specific image or UI element you define and fires a tap only when that element appears. This approach is fundamentally different from timer-based tapping and is genuinely useful when a button appears unpredictably - such as a pop-up reward in an idle game, an enemy that appears at random, or a confirmation prompt that needs to be dismissed whenever it shows.
The app is free and will remain free. It has no data collection and no paid tier. Because it is open source on GitHub, the codebase can be inspected by anyone. For privacy-conscious users who are wary of closed-source auto clickers, Klick'r is the most transparent option available. The learning curve is steeper than most competitors - image detection configuration requires setting up image matching zones and thresholds rather than just dragging a crosshair. For users who want simpler tap automation, Auto Clicker - Automatic Tap or QuickTouch are easier starting points. The full Android auto clicker comparison is at best auto clickers for Android.

Enabling Accessibility Permission
All no-root Android auto clickers use Android's Accessibility Service to simulate taps on other apps. This permission is required for the app to function.
- Open Settings on your device.
- Navigate to Accessibility > Installed Services or Downloaded Apps.
- Find Klick'r in the list and tap it.
- Toggle the Accessibility Service to On.
- Confirm the system permission dialog.
- Return to Klick'r. The service is now active.
Configuration
- Open Klick'r and tap the + button to create a new scenario.
- Give the scenario a name (for example, the game it is used in).
- Choose your action type. For standard tapping, select Click. For image-detection tapping, select Image.
- For Click mode: drag the position marker to the target location and set the tap interval.
- For Image mode: tap Capture Image and frame the UI element you want the app to watch for (such as a collect button or a pop-up reward). Adjust the detection threshold slider - higher means the match must be more exact before triggering.
- Set the action to perform when the image is detected (tap at a specific location, or tap the detected element itself).
- Add a delay if needed to prevent the action from firing too rapidly after detection.
- Tap the play button to start the scenario. Tap stop to end it.
- Test the image detection by navigating to the game and waiting for the target element to appear. Adjust the threshold if false positives or misses occur.

Troubleshooting
Image detection not triggering when the target element appears
The detection threshold may be set too high, requiring a near-perfect match. Lower the threshold slider slightly and test again. Also ensure the image was captured under the same lighting and resolution conditions as the live game. If the game scales UI elements differently at different screen resolutions, recapture the image.
False positives triggering on the wrong screen element
The threshold is too low, matching elements that look similar to the target. Raise the threshold until only the intended element triggers the action. Also crop the captured image more tightly to include only the unique part of the target button.
App crashes when starting a scenario
Check that both Accessibility Service and any required screen capture permissions are granted. Some Android versions prompt for media projection access separately when image capture is first used. Go to Settings > Apps > Klick'r > Permissions and verify all required permissions are granted.
