Why I built it

Renda-kun began as a small personal utility for automating repetitive taps on Android. The goal is to keep the workflow local, visible, and easy to control without requiring root access.

Current features

NO ROOT REQUIREDLOCAL TAP EXECUTIONFREE + ONE-TIME PRO
TAP SEQUENCE
  • Ordered tap points with individual wait and hold times
  • Drag numbered markers or edit coordinates
  • Save settings locally in named presets
  • Free: two presets, up to five points per preset
FLOATING CONTROLS
  • Start and stop from the floating toolbar
  • Add or remove points while stopped
  • Collapse the toolbar and restore it when needed
  • Point markers hide during execution and return after Stop
VISIBLE EXECUTION
  • A foreground service keeps a started sequence running
  • Stop from the app, overlay, or ongoing notification
  • Automation stops before a Google Play purchase and never resumes automatically
PRO · IN TESTING
  • One-time Google Play purchase and restore; no subscription
  • Higher preset and point limits
  • Optional timing and coordinate randomization
  • Loop-count or duration-based stop conditions
SETTINGS
  • Japanese, English, and Simplified Chinese interface
  • Local presets and preferences; no app account or advertising
  • A quiet Settings update hint from the goldBug version feed, checked at most once per 24 hours

Permissions

Everything the app asks for, and why. Nothing runs invisibly.

Known limitations

  • Internal testing only; the app is not publicly available yet
  • The first tap can be missed in the current Play test build; a fix still needs Play verification
  • Accessibility and overlay permissions must be granted manually
  • Battery optimization and device-specific restrictions can affect long runs
  • Locked-screen behavior is not guaranteed; image recognition is deferred
