Quick overview

Simple Sequential Timer is a flexible Android timer created by ototokun. It supports durations from 1 second up to 9 hours, 59 minutes, and 59 seconds, making it suitable for short bursts and long sessions alike. The app is built to be adaptable for many daily uses and workout styles.

Practical uses and situations

This timer works for a wide variety of activities and routines, including:

  • Day trading and other time-sensitive financial tasks
  • Zero-second thinking drills and rapid-response exercises
  • Freewriting or creative sprints
  • Repetitive daily tasks and workflow cycles
  • Strength and muscle-focused training
  • General fitness and exercise sessions
  • Focused study blocks and revision
  • Meditation and breathing practices
  • Kitchen timing and cooking tasks
  • Interval sessions and circuit sets
  • High-intensity interval training (HIIT)

Who benefits most

Office staff and remote workers can use the app to support healthier habits: it can notify you to stand up regularly to reduce the risks associated with prolonged sitting. Beyond desk workers, athletes, students, writers, and hobbyists will find the timer useful for structuring time and maintaining rhythm.

Core features and controls

The app offers numerous customization and control options, for example:

  • Start cues that can be audio, vibration, or spoken TTS announcements
  • Automatic pause/resume behavior to handle interruptions
  • Background operation and compatibility with device sleep modes
  • Background music (BGM) playback choices to set a mood or pace
  • Optional repeating “tic-tac-toe” style chimes for cyclical feedback
  • Dark theme for low-light use and reduced eye strain
  • Custom sound selection for alerts and end-of-interval notices
  • Configurable stand-up reminders (default: every 30 minutes)

Alternative recommendation

If you’re also interested in a companion utility for phone calls, consider the Call Voice Changer — “Voice Changer for Phone Call Free” as a suggested alternative. It provides a different suite of features focused on live-call voice effects rather than timing and session management.
