Why Use a Study Timer?
Procrastination usually isn't laziness — it's tasks that feel too big. Splitting study into short, timed sessions makes starting easy and keeps your brain fresh.
"Focus for 25 minutes" is far easier to start than "study all evening." Small timers remove the mental hurdle.
Regular short breaks let your brain rest and consolidate memory, so three focused hours beat five exhausted ones.
A ticking session creates a gentle deadline that pushes you to ignore distractions and finish one thing at a time.
How the Pomodoro Technique Works
- Set the focus timer — pick Focus mode (25 min) and start one task.
- Do deep work — go until it rings; note distractions instead of acting on them.
- Take a short break — 5 minutes to stretch, hydrate, or walk (not scroll).
- Take a long break — after 4 sessions, rest 15–30 minutes to recharge.
Based on the Pomodoro Technique created by Francesco Cirillo. Pro tip: pair this timer with your Attendance Planner to hit both study and class targets.
Pomodoro vs 52/17 vs 90-Minute Sessions
Best for revision, reading, and shorter tasks or when motivation is low. Easy to start, frequent wins.
Great for coding, essays, and problem sets — long enough to hit flow, with a proper reset between blocks.
Matches the brain's natural focus cycle for heavy topics. Best when you're already warmed up and undisturbed.
There's no single "best" — set your own numbers in the timer and use the planner to see how each choice changes your total study time.
Frequently Asked Questions
What is the best study-to-break ratio?
The classic ratio is 25 minutes focus to 5 minutes break (Pomodoro). For deep subjects like maths or coding, many prefer 50/10 to stay in flow. This tool lets you set any ratio.
How many study sessions should I do per day?
Beginners can aim for ~4 sessions (about 2 hours of focus). As stamina grows, build up to 8–10 a day. The session tracker counts your daily total.
Does the timer keep running if I switch tabs?
Yes. It's time-based, not tick-based, so it stays accurate in the background, and the tab title shows the remaining time while you read.
Is the Pomodoro Technique good for students with ADHD?
Many find it helpful — short timed sessions make time concrete and give frequent breaks as small rewards, making focus easier to start and sustain.
What is the 52/17 rule?
Work with full focus for 52 minutes, then rest for 17. It suits longer, deeper sessions. You can set these numbers in both the timer and planner.
How do I calculate how long my study plan will take?
Use the study session planner: enter your target hours and session lengths, and it shows sessions needed, total break time, full clock time, and your estimated finish time.
