# Collections & Rankings
> Organize your personal strain collection with status tracking, and rank your favorites using an ELO-based comparison system.
## Overview
High IQ's Collection system lets you organize every strain you encounter into meaningful categories, while the Rankings feature uses a competitive ELO-based comparison system to determine your personal all-time favorite strains. Together, they help you build a curated cannabis library and definitively answer the question: "What is my number one strain?"
## Collection Management
Your collection is a unified view of every strain you have interacted with, organized by status. Each strain can hold one or more statuses simultaneously.
### Collection Statuses
| Status | Meaning | Icon |
| ------------ | ------------------------------ | -------------------- |
| **Owned** | Currently in your stash | Active inventory |
| **Tasted** | Tried but do not currently own | Experience logged |
| **Wanted** | On your wishlist to try | Future purchase |
| **Disliked** | Tried and did not enjoy | With optional reason |
A strain can have multiple statuses. For example, a strain you currently own and have previously tasted would show both "Owned" and "Tasted" badges.
### Collection Tabs
The Collection screen uses a segmented tab bar with 6 filters:
| Tab | Shows |
| ----------- | ------------------------------------------------------------ |
| **All** | Every strain in your collection regardless of status |
| **Favs** | Strains you have favorited (separate from collection status) |
| **Owned** | Strains currently in your stash |
| **Tasted** | Strains you have experienced |
| **Wish** | Your wishlist of strains to try |
| **Dislike** | Strains you want to avoid |
### Managing Your Collection
Open any strain profile and use the collection action buttons to set its status as owned, tasted, wanted, or disliked.
Strains added to your stash are automatically marked as "owned" in your collection.
Open the Collection screen to view all strains, filter by tab, sort by rank or name, and switch between card variants.
Long-press or use the action menu on any collection item to change its status or remove it entirely.
### Card Variants
Switch how collection items are displayed:
| Variant | Style |
| -------------- | ------------------------------------------------- |
| **Collection** | Default grid with status badges and rank position |
| **Mascot** | Illustrated mascot cards |
| **Strain** | Photography-focused cards |
| **Split** | Side-by-side image and details |
| **Condensed** | Compact grid view |
| **Compact** | Minimal list view |
## Strain Rankings
The Rankings feature uses an **ELO rating system** (the same algorithm used in chess) to create your definitive personal strain rankings. Instead of rating strains on a scale, you compare them head-to-head -- which naturally produces a more honest and consistent ranking.
### How ELO Ranking Works
You need at least **3 experienced strains** (owned or tasted) in your collection to start ranking.
Tap "Start Ranking" to begin a series of A/B comparisons. Each round presents two strains side by side.
For each pair, pick the strain you prefer, declare a tie, or skip. Each choice updates both strains' ELO scores.
After several comparisons, a natural ranking order emerges. Your #1 strain rises to the top, and less-preferred strains settle lower.
### ELO Score Details
| Metric | Description |
| ------------------------ | ------------------------------------------------------------------------------------------------------------------------------- |
| **ELO Rating** | Starts at 1200 for every strain. Wins increase it, losses decrease it. The magnitude of change depends on the expected outcome. |
| **Rank** | Your calculated position (1 = best). Based on ELO score among all your experienced strains. |
| **Comparisons** | Total number of head-to-head matchups for this strain. |
| **Wins / Losses / Ties** | Breakdown of comparison results. |
### Ranking Sessions
Comparisons are grouped into **ranking sessions** to prevent fatigue. Each session tracks:
* When it started and ended
* How many comparisons you completed
* How many you skipped
You do not need to compare every possible pair. The ELO algorithm converges quickly -- after about 3-5 comparisons per strain, the rankings become stable and meaningful.
### Viewing Your Rankings
Your current rankings are visible in multiple places:
* **Collection screen** -- Sort by "Ranking" to see strains ordered by ELO position
* **My Rankings screen** -- A dedicated view of your ranked strains with ELO scores
* **Home Dashboard** -- Rankings Preview section shows your top 5
* **Stats Dashboard** -- My Strains tab includes ranking data
## Favorites vs. Collection
High IQ has both a **Favorites** list and a **Collection** system. Here is how they differ:
| Feature | Favorites | Collection |
| ------------ | -------------------------- | ------------------------------- |
| **Purpose** | Quick bookmarking | Full tracking with statuses |
| **Statuses** | Favorited or not | Owned, Tasted, Wanted, Disliked |
| **Ranking** | No | Yes (ELO comparisons) |
| **Notes** | Yes | Yes |
| **Photos** | No | Yes (photo uploads) |
| **History** | Favorite/unfavorite events | Full event audit trail |
**Favorites are great for quick bookmarks** -- strains you want to remember or revisit. **Collection statuses** are for tracking your full cannabis journey with deeper detail.
The **Dislike** status is useful for avoiding repeat purchases. When you mark a strain as disliked with a reason (e.g., "gave me anxiety"), you will see a warning if it appears in recommendations.
