Simple Interval Timer – Flexible Timing for Any Activity

What is Simple Interval Timer?

Simple Interval Timer is a lightweight Android utility that lets you create and run custom timing sequences. Whether you are structuring a high‑intensity interval training (HIIT) session, timing a pomodoro study block, or setting up intervals for a run, the app provides a clear, uncluttered interface for defining work and rest periods down to the second.

Main features

• Fully customisable intervals – Choose any duration for work and rest phases, and set the number of cycles you need.
• Save presets – Create named presets for recurring routines and load them with a tap.
• Background operation – The timer continues when you switch apps or lock the screen.
• Minimalist design – Large, easy‑to‑read numbers and simple controls keep the focus on your activity.
• Free and ad‑free – All functionality is available without payment or advertisements.

How it works

After launching the app, you are presented with fields to enter the length of the work interval, the rest interval, and the total number of repetitions. A single button starts the sequence, and the display updates in real time, showing the remaining time for the current phase and the overall progress. When a preset is saved, you can retrieve it later from the preset list, edit it, or delete it as needed.

Practical uses

The flexibility of Simple Interval Timer makes it suitable for a wide range of activities:

• Fitness: HIIT, Tabata, circuit training, weight‑lifting sets, CrossFit AMRAP or EMOM workouts.
• Cardio: Interval runs, sprint repeats, cycling intervals, rowing drills.
• Mind‑body: Yoga pose timing, meditation sessions, breathing exercises.
• Productivity: Pomodoro study blocks, focused work intervals, break reminders.

Who may find it useful?

Anyone who needs a reliable, easy‑to‑configure timer without the distraction of ads or unnecessary features. The app is particularly helpful for athletes, coaches, students, and anyone who follows a structured timing routine.
