White noise for studying

White noise is the steady hiss of a fan or a radio between stations. It covers chatter, footsteps and traffic, so small sounds stop pulling at your attention.

Ours is softened at the very top so it doesn't feel sharp. Press Start for a 25 minute round; the pup naps beside you until the chime.

Too bright? Try brown noise

If white noise starts to feel harsh, brown noise is deeper and softer, and rain adds a natural texture. They are all in the green Nature mix.

Make it yours

Every sound in the mix has its own slider. Many people keep white noise low with a café murmur or rain on top. Your mix is remembered for next time.

How it works

Pick 10, 25, 50 or 60 minutes (or tap the minutes and type any length up to 2 hours), then press Start. The pup settles in to sleep.

Keep this tab open while you work. If you are away for more than 10 seconds the pup wakes for a peek; the timer keeps counting, but the round earns one biscuit fewer.

When the round ends the pup stretches and you earn dog biscuits: 1 for 10+ minutes, 2 for 25+, 3 for 50+. The jar holds up to 99.

Records

Records are seamless loops you can play under your focus. Rooftop Set and Night Ferry are free, and two more can be unlocked on the web with 4 biscuits each. The rest, from math rock and cool jazz to deep house and Ethio-jazz, have previews here and live in the app.

The green Nature mix record plays ten looping nature sounds you can blend with sliders: rain, waves, campfire, thunder, crickets, snowy wind, café, turning pages, a pool and deep space.

On iPhone, Apple Watch and Android

The Pupmodoro apps add a Lock Screen Live Activity and Dynamic Island countdown, a gentle chime when a round ends, every record and every scene, outfits for your pup, a weekly and monthly journal, focus rounds from Apple Watch, and sync across devices. They are a subscription with a 7-day free trial; the web version stays free.

Sleep log

Every round lands in the Sleep log: today's rounds on a little timeline, and this week as crayon bars with the biscuits you earned each day.

Questions

How loud should white noise be?

Just loud enough to blur the sounds around you, which is usually lower than you'd think. Start low and turn it up only until distractions fade.

Is Pupmodoro free?

The web version is free with no sign-up. The iPhone/iPad app (with Apple Watch) and the Android app are a subscription with a 7-day free trial on the yearly plan: $29.99 a year, $4.99 a month, or a one-time $49.99.

Does the timer keep running if I switch tabs?

Yes. The countdown never pauses. Being away for more than 10 seconds only wakes the pup and costs the round one biscuit.

Do I need an account?

No. Your biscuits, records and sleep log are saved in your browser. Sign in with Google only if you want them on your other devices and in the app.

What is the music?

Original instrumental loops made for Pupmodoro: lo-fi, neo-soul, bossa nova, cool jazz, deep house and more, with no vocals.
