SpoPulse – Timer, Counter & Metronome

What is SpoPulse? (Sport + Pulse)

SpoPulse is a free, web‑based (and offline‑capable) timer, counter, and metronome designed for workouts, running, swimming, cycling, strength training, and any activity where rhythm helps.

Why I created it

I exercise occasionally. Swimming, cycling, lifting weights, and more. I don't do it daily, it's just something I do when I feel like it. I started back in middle school, and after all these years, it's still a part of my life. I do it to stay healthy, and it also helps me feel good about myself.

About a year ago I began using a metronome app to keep track of repetitive movements. It worked nicely. No need to count myself, and the beats helped me stay in sync. But the app had limitations unless I paid, and I didn't want to use the Play Store, so I couldn't make in-app purchases. After many months I decided to build my own web app. As a web developer, I could build it myself — and now I have something even better than what I originally wanted.

While coding, I added features I didn't even expect from the original app. What started as a simple metronome now includes timed sounds, workout tracking, and more—all without needing an account, installation, or payment.

Key Features

BPM Control – Set beats per minute (e.g., 40 BPM means a beat every 1.5 seconds).
Rich Sound Library – Over a dozen royalty‑free samples sourced from Freesound.org. Each sound retains its original ID (e.g., "457631") so you can easily locate the creator's page.
Customizable Groups – Combine multiple sounds into a single beat pattern to make them a group.
Four Repeat Modes – Choose between beats, duration, beat‑as‑group, or duration‑as‑group.
Finite or Infinite Repeats – Loop forever or stop after a set count.
Markers & Progress Indicators – Add cues to track milestones during a session.
Plan Preview – See every gap, its tempo range, and running totals.
Share Link – Encodes your entire setup into a single URL.
Themes & Text Scaling – Pick from several UI themes and adjust text size for optimal readability.
Beat Animations – Choose from seven visual styles that peak exactly on each beat.
Wake Lock & Fullscreen – Keep the screen on and go edge‑to‑edge while playing.
No Ads, No Purchases – All features are available without signing up or paying.
