​
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

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:

​
Managing Your Collection

1

Add from Strain Profile

Open any strain profile and use the collection action buttons to set its status as owned, tasted, wanted, or disliked.
2

Add from Stash

Strains added to your stash are automatically marked as “owned” in your collection.
3

Browse and Organize

Open the Collection screen to view all strains, filter by tab, sort by rank or name, and switch between card variants.
4

Remove or Update

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:

​
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

1

Build Your Collection

You need at least 3 experienced strains (owned or tasted) in your collection to start ranking.
2

Start a Ranking Session

Tap “Start Ranking” to begin a series of A/B comparisons. Each round presents two strains side by side.
3

Choose Your Preference

For each pair, pick the strain you prefer, declare a tie, or skip. Each choice updates both strains’ ELO scores.
4

Watch Rankings Emerge

After several comparisons, a natural ranking order emerges. Your #1 strain rises to the top, and less-preferred strains settle lower.

​
ELO Score Details

​
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:
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.
