Quick answer
A 43-page ebook and printable workbook about focus intervals. It traces 12 popular timings — 25/5, 12/3, 50/10, 52/17, 90/20, 45/15, the ten-minute starter, Flowtime, timeboxing, time-blocking, the 20-20-20 eye break and exam-match sessions — back to where the numbers came from, grades the research behind each one, and gives you a 14-day experiment with printable logs to find the interval that fits you. Instant PDF in A4 and US Letter.
Why 25 minutes? Where did 52/17 come from? Is the 90-minute rule real? Most focus advice repeats numbers without saying where they came from. The Interval Atlas does the digging — a kitchen timer in the late 1980s, a time-tracking app’s 2014 data, a sleep lab, a school timetable — and explains in plain English what controlled studies have actually found.
What’s inside
- Part 1: the research — fixed vs self-chosen breaks (2023 and 2025 studies), how long a break should be (a 2022 meta-analysis of 2,335 people), why phone breaks may not rest your attention, and five popular myths traced to their sources
- Part 2: 12 timings — two pages each: origin, evidence badge, a two-hour timeline, best for and watch out for, settings for 25Mint, LCD and LED flip timers, and a try-it-today plan
- Part 3: the Interval Finder — two questions pick your two best candidates
- Part 4: the 14-day experiment — baseline, alternate A and B, tune and confirm, with a simple decision rule and a worked example
- Printables — daily interval log, 14-day scoreboard, break menu, cut-out interval cards and a one-page summary
- Sources — a full reference list so you can check every claim

Frequently asked questions
Is this a summary of the Pomodoro Technique book?
No. It covers 12 different timing methods, including the classic 25/5, and focuses on where each number comes from and what independent research has found. 25Mint is not affiliated with Francesco Cirillo.
Does it help with ADHD?
It includes short-interval options that many people with ADHD find easier, such as the 12/3 Micro Loop and the ten-minute starter. It is general information, not medical advice.
Do I need a special timer?
No. Any timer works. Settings are included for the 25Mint, LCD and LED flip cubes we sell.
