Your Cannabis Journal CannaTrak is your cannabis journal — a single place to track everything about your licensed cannabis experience, built for speed and designed around your data. Built for speed. CannaTrak makes journaling easy. Scan a label or COA at the point of purchase, log usage with a single tap, and record how you were feeling and what you were doing in seconds. See your analysis right away — CannaTrak is designed to turn your entries into insight, fast. Your personal catalog. Every dispensary purchase becomes part of your journal — organized, searchable, and easy to look back on. Mark favorites, and keep your whole current stash ready for one-tap logging. Quick entries, every time. Took a hit from the vape pen? Log it in seconds and see your THC intake alongside how it made you feel and what you were doing at the time. Ate a gummy? Record it — mood, activity, and all — with a single click. Understand what you like. Sativa and indica labels don't actually appear on a COA — but terpene data does, and it's a much better predictor of what works for you. The more you journal, the sharper your instincts get. The full picture. Use CannaTrak to track usage, log how you felt or what you were doing, record abstinence or a craving, or simply keep tabs on your stash, dispensaries, and spending. CannaTrak is about the data — your journal, your history, your patterns. Your data, your call. Store your journal locally and delete it instantly, or sync across your devices — you decide. CannaTrak never tracks usage data back to you. Give it a try, and start keeping your cannabis journal.

Verdict
The clearest difference is in-app purchases: CannaTrak at none against KO3's 4. CannaTrak also leads on update cadence (every 4 days vs every 3 months) and iOS requirement (15.0 vs 27.0). On price, ads and device support there is nothing between them.
