Set your break threshold, watch the live risk gauge, and get pulled out of hyperfocus before you lose four hours, forget to eat, and crash hard.
You sit down at 1 PM to fix one thing. You look up and it is dark, your water glass is full and warm, your back is locked into a shape, and you cannot remember the last time you ate. The work got done — and the crash that follows will eat tomorrow morning to pay for it. That is hyperfocus: the best and most expensive thing your ADHD brain does. The ADHD Hyperfocus Detector and Break Reminder runs a live session timer with a configurable break threshold, a risk gauge that fills as the session drags on, and body-care chips — Hydrated, Ate, Moved, Eye Break — that nudge you toward the basic maintenance deep focus quietly switches off.
The premise is simple: you are not going to notice the time passing. That is not a failure. That is hyperfocus working exactly as it does. The tool notices for you and intervenes before the session has gone far enough that the crash is inevitable. You set the threshold, name the task, and let the gauge tell you when the risk of staying in is higher than the cost of stopping.
The live risk gauge: what it is tracking
The live risk gauge fills progressively as your session extends past defined windows. A session in the early stages shows low risk. As time approaches and then passes your break threshold — the default is 120 minutes — the gauge enters the warning zone. Past threshold, the gauge shows OVERDUE and the tool fires the break alarm.
The gauge is a visual urgency signal calibrated to work for a brain that has been filtering out environmental cues for the past 90 minutes. A notification you can dismiss in a second is ineffective. A filling gauge that you can glance at periodically is a softer intervention that ADHD brains tend to respond to because it is visual and immediate rather than textual and abstract.
The Break Threshold input lets you set your personal threshold — some people should not go past 60 minutes without a break; others function well at 90 or 120. The default of 120 minutes is a reasonable starting point; adjust based on how you feel in the hours after long hyperfocus sessions.
Body-care chips: the physical maintenance that falls off during hyperfocus
The body-care chip interface — Hydrated, Ate, Moved, Eye Break — is one of the most distinctive features of the Hyperfocus Detector. Each chip represents a basic physical need that commonly goes unaddressed during hyperfocus sessions because the brain is entirely occupied with the task.
You tap each chip when you complete the action. Hydrated means you have had water since the session started. Ate means you have had something to eat. Moved means you have changed position, stood up, or moved your body. Eye Break means you have looked away from the screen for at least 20 seconds, giving your eyes something other than close-distance digital content to focus on.
The chips are not a strict checklist. They are a prompt that asks your brain to notice whether these things have happened. For many people, the act of looking at the chips and realizing they have not had water in two hours is enough to trigger the behavior — not because they forgot that water exists, but because hyperfocus actively suppressed the internal signal that usually reminds them.
Session history: over-threshold frequency and patterns
The Sessions tab logs every session you have run, including whether it stayed under threshold, went over threshold without breaking, or was properly ended by a break at threshold. The Over Threshold stat in the dashboard is the one to watch: how often are you going past your threshold and continuing to work? A high over-threshold rate means the alarm is firing but you are dismissing it rather than stopping.
This pattern — frequent over-threshold sessions — correlates in most users' data with worse post-session crashes, more difficulty returning to productive work the following day, and higher burnout risk. Seeing your over-threshold rate rising over two or three weeks is an early signal that your hyperfocus pattern is starting to cost you more than it is producing.
Longest session and average session: what the data tells you
The Longest Session metric shows your personal hyperfocus record — the single longest session you have run. For most ADHD adults, this number is longer than they think it will be. A session logged at 4 hours and 22 minutes is not unusual. That number, seen clearly, is usually more motivating than any advice about taking breaks.
The average session length tells you whether your typical work sessions are within a range that your body and brain can sustain, or whether you are regularly running past the point where the output-per-hour starts to decline. Most cognitive work shows diminishing returns past 90-120 minutes of continuous focused effort. Sessions beyond that are often producing lower-quality output than sessions that include a break at the right point.
Using the Snooze function without abusing it
When the OVERDUE alarm fires, the tool offers a Snooze 10 min option. This is not there to help you ignore the break indefinitely. It is there for the moments when you are genuinely 8 minutes from a natural stopping point — finishing a paragraph, completing a code block, reaching the end of a section — and an immediate stop would be more disruptive than a brief extension.
The Snooze should be used once per session at most. If you find yourself snoozing repeatedly, the threshold is set too short for your current task or the alarm is not working as intended. Reset the session and adjust. Consistent snoozing without ever actually taking a break is the pattern most likely to end in the crash the tool is designed to prevent. Catch the spiral before it costs you 4 hours.
How to use it
- Name your task in the 'What are you focusing on?' field, then set your Break threshold (default 120 minutes).
- Start the session and keep the monitor visible while you work — glance at the live risk gauge periodically.
- Tap the body-care chips (Hydrated, Ate, Moved, Eye Break) each time you do them during the session.
- When the OVERDUE alarm fires, take a real break — at least 5 minutes away from the task and screen.
- Review the Sessions tab weekly to check your over-threshold rate and adjust your threshold if needed.
Who it's for
- Developer who loses whole afternoons to a single coding problem — Sets a 90-minute threshold. First week shows 6 sessions, 4 of them over threshold. Over the next two weeks, awareness from the gauge reduces over-threshold sessions to 1 in 6. Afternoon crashes decrease significantly.
- Writer who forgets to eat during intensive drafting sessions — Taps the Ate chip every time they eat something during a session. Discovers that in the first two weeks, the chip goes untapped in 70% of sessions lasting over 90 minutes. Adds a physical snack on the desk as a passive eating prompt.
- Graphic designer with neck and back pain from long focused sessions — Sets the Moved chip as the primary body-care target. Breaks sessions at the threshold, stands up, and does two minutes of movement. Pain is noticeably reduced within three weeks of consistent threshold breaks.
- ADHD researcher finishing a dissertation chapter — Runs the detector during every work session. Longest session in the first month: 3 hours 47 minutes. Over-threshold rate: 65%. After adjusting threshold to 75 minutes and committing to real breaks, post-session energy is meaningfully better and the next day's session starts faster.
Key terms
- Hyperfocus
- An ADHD-associated state of intense, sustained attention on a task to the exclusion of other stimuli including hunger, thirst, fatigue, and time awareness. Valuable for output but costly when unmanaged.
- Break threshold
- The session duration at which the tool fires the break alarm. Set by the user based on their individual capacity for sustained focus before cognitive or physical costs accumulate.
- Body-care chips
- The Hydrated, Ate, Moved, and Eye Break check-ins that track basic physical maintenance during a focus session. Log the behaviors that hyperfocus suppresses the internal signals for.
- Over-threshold rate
- The percentage of sessions that go past the break threshold without a break being taken. A rising over-threshold rate is an early indicator of unsustainable hyperfocus patterns.
Frequently asked questions
What should I do during the break that the alarm calls for?
Move your body, look away from the screen, eat or drink if those chips are untapped, and ideally spend at least 5 minutes away from the task mentally as well as physically. A bathroom break while thinking about the next part of the work does not fully rest the cognitive systems that hyperfocus taxes. The goal is a genuine pause, not a physical movement with continued mental engagement.
My best work happens in long hyperfocus sessions. Is the threshold hurting my productivity?
The quality of output in a session and the quality of output on the days following a session are different metrics. Long hyperfocus sessions often produce good work in the moment while significantly impairing the following day's productivity due to burnout and recovery demands. The threshold is not designed to prevent good work — it is designed to prevent the crash that makes good work harder for the next two days.
Can I set different thresholds for different types of work?
Yes — adjust the threshold at the start of each session based on what you are doing. Creative work that involves high emotional engagement may need a shorter threshold than analytical work. Manual or physical tasks might tolerate a longer one. The threshold is a per-session input, so it can and should vary.
Does the alarm work if I have the tool in a background tab?
The tool is designed to work in an active browser tab. If you need background monitoring, keep the tab visible in a second monitor or window arrangement. The live risk gauge requires the tab to be at least occasionally visible to serve its function as a visual intervention.
