Thunderstorm sounds to study to

Some people focus best with a storm outside: heavy rain on the window and thunder rolling far away. This page mixes both under a 50 minute timer, long enough for a real stretch of deep work.

The pup sleeps right through it. Slide the thunder up or down in the Nature mix, or add the snowy wind for a winter storm.

Your storm, your volume

In the green Nature mix the thunder and the rain have separate sliders, so you can keep a distant rumble under steady rain or turn the whole storm up. Add wind for a stormy night, or a fire for the feeling of being warm indoors while it pours.

Good for long sessions

Storm sounds suit long, heads-down work: writing, reading, revising for an exam. Pair them with a 50 minute or 1 hour round and let the storm run for the whole session.

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

Is the thunder loud or sudden?

No. The thunder is distant and rolling, mixed low under the rain, so it never jolts you out of focus. You can turn it down or off on its own slider.

Can I hear rain without the thunder?

Yes. Open the green Nature mix and slide the thunder down to zero, or use the rain sounds page, which starts with rain only.

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.
