Four tools that show their work
Every recommendation here is produced by rules you can read. No black box, no sponsored placement — and each tool ships with a full guide explaining its method and limits.
01
Perfume Finder Quiz
A three-input quiz cannot know your skin, but it can eliminate 90% of a catalogue. Here is exactly what each answer changes, how the scoring works, and where a machine recommendation stops being useful.
02
Fragrance Note Finder
Most people discover fragrance through a single note. This guide explains how the finder weights top, heart and base placement, and why the same note behaves completely differently in each layer.
03
Perfume Season Calculator
August in Tokyo and August in Stockholm are not the same fragrance problem. This guide explains the temperature and humidity thresholds the calculator uses, and how to apply them to any city.
04
Perfume Longevity Guide
EDP 6-10 hours, EDT 3-5, cologne 2-3. Those numbers are real averages but they are not the main driver of longevity — material volatility, skin type and application are.
