Every tool, in one place.
A complete catalog of every calculator, simulator, and interactive instrument across all four LifeByLogic labs. Each runs in your browser. Nothing is stored. Everything is free.
Brain Age Index
Estimate the modifiable portion of your brain-age gap across 6 evidence-based domains (25 items). Built on the 2024 Lancet Commission and UK Biobank research (n=38,967).
LBL Sleep-Cognition Optimizer
12-item behavioral sleep assessment with personalized 24-hour schedule. Computes social jetlag and Sleep Regularity Index estimate. Reveals biology-behavior gap when paired with Chronotype Profile. 3–4 minutes.
Cognitive Reserve Estimator
Estimate your accumulated cognitive reserve across six evidence-weighted domains: education, occupational complexity, cognitive leisure, social engagement, multilingualism, and physical activity with cognitive demand. Synthesized from Stern's framework, the CRIq, Verghese 2003, and the 2024 Lancet Commission.
LBL Chronotype Profile
14-item LBL-original biological chronotype assessment grounded in 2019-2025 chronobiology (Jones 2019 GWAS, Taillard 2004 age calibration). Continuous 0–100 score, age-sex calibrated, with estimated DLMO window. 4–5 minutes.
Sleep Need Calculator
How much sleep do you need by age? Built on AASM and NSF consensus guidelines, with weekly sleep debt and a lifespan view.
Adult ADHD Test
Free ~7-minute screen using the LBL Adult ADHD Symptom Inventory (v2.0): a 20-item LBL-original inventory across three domains (attention, hyperactivity, emotional self-regulation), with severity bands and 7 research-grounded archetypes. A screen, not a diagnosis.
Adult Autism Test
A free ~8-minute adult autism self-inventory using the LBL Adult Autism Self-Inventory (v2.0), a 30-item LBL-original instrument across four trait constructs (social-cognitive, sensory, routine & repetition, focus & depth) plus masking and emotional-processing context indices. Returns a trait profile, four resonance bands, and one of six lens profiles. A self-inventory, not a diagnosis.
Brain Vitality Index
A free ~14-minute live cognitive performance test. Seven short tasks adapted from established paradigms (Corsi span, Eriksen flanker, Symbol–Digit, task-switching, paired-associate) measure seven domains and yield a Brain Vitality Age and cognitive archetype. Optional paid report. A performance snapshot, not a diagnosis.
Should I Quit?
Monte Carlo decision tool for the stay-or-leave question. Integrates the Copenhagen Burnout Inventory (Kristensen 2005), Work and Meaning Inventory (Steger 2012), and validated turnover research. 10,000 simulated futures for both paths across 3, 5, or 10-year horizons.
Career Choice Signature
Maps how you naturally create value at work across nine value-creation modes and six operating conditions, producing your Value Signature, a Coherence score, and one of eleven archetypes. A portable lens for any role, grounded in career-construction theory, work design, behavioral economics, and human-capital research. Free to take; optional in-depth report.
Career Pivot Decision Matrix
Structured 6-domain weighted comparison of your current role and the pivot you're considering — plus a calibration check on how informed your evaluation actually is. Decision-quality forcing function based on multi-attribute utility theory and career capital research.
Cognitive Bias Susceptibility
A ~15-minute assessment of susceptibility to seven well-studied cognitive biases using behavioral tasks — not self-report alone. Grounded in the Stanovich/West/Toplak CART framework (MIT Press 2016), Bruine de Bruin's A-DMC scale, and the Bias Blind Spot research from Carnegie Mellon.
Big Five Personality Snapshot
A 2-minute Big Five personality assessment using the validated BFI-10 (Rammstedt & John 2007). Scores all five trait dimensions (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism) with normative percentile bands.
Anxiety Test
A validated 7-item GAD-7 anxiety screen (Spitzer 2006) with severity bands, symptom profile (cognitive / somatic / behavioral), 5 archetypes, and evidence-based pathways. ~2 minutes, browser-local.
LBL Future Self Continuity Index
An 18-item self-reflection inventory measuring future self continuity (Hershfield 2011; Sokol & Serper 2020) across three dimensions — similarity, vividness, positivity — at 1-year and 10-year horizons. Derived Time Horizon Stability, 4-quadrant archetype routing with care-aware referral for vulnerable profiles. ~5–7 minutes, browser-local.
The Inner Economy
A 45-question self-reflection inventory mapping how you spend finite drive, attention, and risk across 13 dimensions in three systems — Appetites, Protections, and Treasury — surfacing 10 named tensions and an overall Coherence reading. LBL-original and unvalidated; a structured self-reflection prompt, not a clinical instrument.
LBL Rumination Loop Mapper
Maps how you ruminate, not just whether you do — 28 items across seven factors. Built on Treynor & Nolen-Hoeksema's brooding–reflection distinction (2003), Wells's metacognitive model (2003), and the Perseverative Thinking Questionnaire (Ehring 2011). ~6 minutes, browser-local. Educational, not a clinical instrument.
TypeAtlas
A 32-statement, 16-type personality test returning your four-letter type with per-trait confidence and closest-fit alternatives, plus a full profile across career, relationships, communication, stress, and growth — careers grounded in O*NET labor-market data. LBL-original; educational, not clinical. ~5–7 minutes.
Flourishing Index
LBL-original 25-item assessment measuring 16 dimensions across 9 core and 7 contextual facets, with 6-archetype classification including care-aware crisis routing. Benchmarked against the Global Flourishing Study Wave 1 (2025) from 200,000+ participants across 22 countries.
Attachment Style Decoder
Find your attachment style across two dimensions — Anxiety and Avoidance — placed on a four-archetype quadrant. An LBL-original 20-item instrument grounded in the two-factor adult attachment framework (Brennan, Clark & Shaver 1998; Mikulincer & Shaver 2007), with science-grounded archetypes and pathways toward earned-secure attachment.
Meaning in Life Questionnaire
A 2-minute meaning assessment using the validated MLQ (Steger et al. 2006). Scores Presence and Search subscales with a 2×2 quadrant placement (Settled, Growth-oriented, Seeking, Disengaged) plus normative percentile bands.
LBL Depression Test
A validated 9-item depression screen (Kroenke 2001) with 5 severity bands, symptom profile, 5 archetypes, evidence-based pathways, and item-9 hard-escalation crisis support. ~3 minutes, browser-local.
Stress & Burnout Index
A 16-item LBL-original self-inventory (LBL-SBI v1.0) measuring perceived stress and personal burnout, with construct anchors from Cohen 1983 (PSS-10) and Kristensen 2005 (CBI Personal Burnout). 5 archetypes on a stress × burnout map, care-aware escalation, browser-local. ~4 minutes.
LBL Loneliness Test
A combined 23-item screen pairing the UCLA-3 brief screen (Hughes 2004) with the UCLA Loneliness Scale Version 3 (Russell 1996). Three-factor decomposition (Intimate, Relational, Collective), 5 archetypes, care-aware escalation, browser-local. ~5 minutes.
