Remember Every Plant, Permanently
PlantRef tracks how well you know each plant and schedules reviews at scientifically optimal intervals. Plants you struggle with come back quickly. Plants you know well fade into longer cycles — up to 6 months between reviews.
Study Any Quiz Mode
Every answer across all four quiz types — flashcards, multiple choice, plant parts, and writing — feeds the same review system.
Intervals Adjust Automatically
Got it right? Your next review pushes further out — 1 day, 3 days, a week, a month. Got it wrong? It resets so you see it again soon.
Review When Due
When plants are ready for review, your dashboard shows the count. One click starts a focused session with just the plants you need.
Five Mastery Levels
Each plant progresses through these stages as you review it over time
Multi-Mode Bonus
Study a plant across 3 or more quiz types and your review intervals get a 10% boost — the variety strengthens retention.
Study Streaks
Complete at least one review session per day to build your streak. Consistency is the single strongest predictor of long-term retention.
