Guide

Timer techniques that keep you focused

A study timer measures time — and it can also create focus. Here are three techniques you can start using today.

Work in Pomodoro blocks

The Pomodoro Technique repeats one set of “25 minutes of focus, then a 5-minute break.” Human concentration doesn't last long, so short blocks keep your intensity high to the end. After four sets, take a longer 15–30 minute break. MonoStudy's timer starts and stops whenever you like, so it works for 25-minute Pomodoro blocks and for long, uninterrupted deep-work sessions alike.

Lower the barrier to starting

The biggest reason studying doesn't stick is the inertia before you sit down. Decide in advance that “pressing the timer means studying has started,” and there's nothing left to deliberate. Motivation follows action, not the other way around — starting the timer with one tap is the shortest path.

Just measuring increases study time

Recording your own behavior changes it — a well-known effect called self-monitoring. When today's total is visible as a number, “ten more minutes” comes naturally. Your tracked time is totaled automatically, so review weekly trends in study stats and pair them with a daily goal to build a loop of record → goal → keep going.

FAQ

Frequently asked questions

Can I use it in the browser alone?
Yes. Open the app page in your browser and it works as is. There is no install and no sign-up — you can start tracking anonymously right away. Log in only when you want to see your records on more than one device.
Does it work on a phone browser?
Yes. It behaves on a smartphone browser just as it does on a desktop. Add it to your home screen and it launches like an app with one tap.
Will my recorded study time be lost?
The moment you stop the timer, your study time is auto-saved to the cloud (Firebase). Stay logged in and you will see the same records on any device. If you use it anonymously, clearing your browser data can leave you unable to get back to your records, so we recommend logging in if you plan to keep at it. See the Privacy Policy for details.
Is it free to use?
Yes. The study timer and your study-time records are free. Premium (¥280/month) covers extras such as raising the flashcard limit and viewing study history older than 7 days along with per-tag charts; using the timer itself is never limited.
Can I use it for the Pomodoro Technique?
Yes. Start and stop are entirely up to you, so it works for 25-minute Pomodoro blocks as well as long uninterrupted sessions. Every measured session is added to your records as is.
How long should I study each day?
Consistency matters more than length. Start with a short amount you can reliably finish, then increase it gradually while watching your records. Set a daily goal in goals & streaks to see your remaining time and streak.

So, start tracking.
