Planificateur de session de concentration

The Focus Session Planner calculates optimal Pomodoro-style work and rest session lengths based on five factors: your typical attention span, task complexity, available time, current energy level, and medication status. Designed specifically for ADHD and neurodivergent users who find the classic 25-minute Pomodoro either too long (fatigue, restlessness) or too short (interrupting flow), the calculator adapts session length to your actual brain state. Beginners and unmedicated users may need 10-15 minute sessions; medicated adults working on familiar tasks can sustain 40-50 minute blocks productively. The Pomodoro Technique was created by Francesco Cirillo in the late 1980s using a tomato-shaped kitchen timer ('pomodoro' is Italian for tomato). The standard 25-minute work + 5-minute break structure was designed for neurotypical adults doing routine knowledge work. The technique gained massive popularity through the 2010s productivity movement and remains the most-used time management method globally. However, the rigid 25-minute structure fails many neurodivergent users — ADHD attention varies dramatically based on dopamine availability, novelty, interest, medication, sleep, and emotional state. Adapting session length to actual current capacity outperforms forcing the brain to match an arbitrary schedule. The calculator's algorithm weights each factor based on ADHD and neurodivergent research. Task complexity matters most: novel tasks (learning new skills, unfamiliar work) burn cognitive load 2× faster than routine tasks (familiar email, organized administrative work). Medication produces 15-25% capacity differences — stimulant medications meaningfully extend sustainable attention. Energy level reflects the daily variation that ADHD adults experience: sleep quality, food timing, hormonal cycles, and emotional state all impact same-day capacity. Combining these factors produces personalized session length matched to your actual current state rather than your aspirational state. This calculator helps you plan productive work sessions matched to your brain's current capacity. Enter your typical attention span (be honest — most ADHD adults sustain 15-30 minutes maximum), task complexity, available total time, medication status, and energy level. The calculator outputs work block length (10-50 minutes), break length (3-15 minutes), total sessions possible in your available time, total work and break time, and when to schedule a longer break (typically every 60 minutes of work, 15-30 minute break). Use to structure work sessions that produce actual output instead of forcing failed Pomodoro attempts.

1. 1Step 1 — Enter Your Typical Attention Span: Be honest about your actual sustained focus duration, not your aspirational duration. Most ADHD adults find their honest attention span is 15-30 minutes on routine tasks. Medicated adults: 20-40 min. Hyperfocus periods (90+ min) happen but aren't sustainable as baseline assumption. Track for a week if uncertain — set a timer and note when you naturally lose focus or need to switch.
2. 2Step 2 — Select Task Complexity: Easy/routine tasks (familiar email, organizing files, simple admin): 1.3× multiplier — you can sustain longer than average. Medium tasks (typical work that matches your skill level): 1.0× — standard duration applies. Hard tasks (demanding work within your skill set): 0.7× — burn cognitive load faster. Novel tasks (learning new skills, unfamiliar content): 0.5× — half the typical session length to prevent burnout.
3. 3Step 3 — Enter Available Total Time: How much time you have for the entire focus block, including breaks. Examples: morning work session (180 min), pre-lunch hour (60 min), afternoon block (240 min). Calculator divides this into work + break cycles. Be realistic about interruptions — if your environment has unavoidable interruptions every 60 min, plan blocks around those.
4. 4Step 4 — Select Medication Status: On stimulant at peak (1-3 hours after dose for short-acting, 2-5 hours for extended release): 1.2× multiplier. Non-stimulant medication (steady-state): 1.05×. Unmedicated: 0.85×. Off medication today (forgot, breaks, or strategic): 0.75-0.95× depending on baseline. Schedule cognitively demanding work for peak medication windows.
5. 5Step 5 — Select Energy Level: Low energy (tired, foggy, post-large-meal, end-of-day, illness): 0.7×. Medium (typical daily state): 1.0×. High energy (well-rested, exercise endorphins, novel project excitement): 1.1×. Energy is the most variable factor and worth honest assessment in the moment, not historical average.
6. 6Step 6 — Calculator Computes Session Lengths: Work block = Attention Span × Complexity × Medication × Energy, clamped to 10-50 min range. Break length = Work / 4 (or Work / 3 if Work ≥ 40 min), clamped to 3-15 min range. Total sessions in available time = floor(available / (work + break)).
7. 7Step 7 — Plan Longer Breaks for Multi-Session Work: For work sessions exceeding ~60 minutes total work time, schedule a longer break (15-30 minutes) at appropriate intervals. The calculator suggests 'long break after X sessions' based on cumulative work load. Long breaks should include physical movement, fresh air if possible, and avoid screens to give the brain genuine recovery.

• !Forcing 25-minute Pomodoros when your actual span is shorter — sets you up for failure and gives up on the technique entirely.
• !Skipping breaks during hyperfocus — quality of work declines, post-session recovery time extends, body care neglected.
• !Not accounting for task complexity — novel tasks burn cognitive load 2× faster than routine; same person can sustain very different durations for different work types.
• !Ignoring medication timing — sessions should align with peak medication effect for hard work, ramp periods for routine work.
• !Treating low-capacity days as 'wasted' — micro-sessions (5-10 min) still produce output; insisting on 'real' 25-min sessions produces zero output instead.
